Print quality Use the HP ToolboxFX print-quality options to improve the appearance of print jobs. These are the same options that are available on the product control panel. For more information, see Control panel (HP LaserJet P2050 Series Printers only) on page 22. The four options provided for controlling print quality are resolution, REt (Resolution Enhancement technology), print density, and EconoMode. 54 ● Resolution. Select 600 resolution for average print jobs and FastRes 1200 for higher-quality print jobs. Select ProRes 1200 for the highest-quality print job, but a longer printing time. ● REt. You can turn on REt, which HP provides for improved print quality. Chapter 4 Manage and maintain ENWW ● Print density. For increased print density, select a higher number. For decreased print density, select a lower number. ● EconoMode. Turn EconoMode on when you are printing average print jobs. EconoMode is a feature that allows the product to use less toner per page. Selecting this option might extend the life of the toner supply and might reduce cost per page. However, it reduces print quality. The printed image is lighter, but it is adequate for printing drafts or proofs. HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, it is possible that the toner supply can outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these circumstances, install a new print cartridge, even if there is toner supply remaining in the cartridge. NOTE: You must click Apply before the changes take effect. Paper Types Use these options to configure print modes that correspond to the various media types. To reset all modes to factory defaults, select Restore modes. NOTE: You must click Apply before your changes take effect. System Setup Use these system settings to configure miscellaneous print settings. These settings are not available on the control panel. NOTE: You must click Apply before your changes take effect.

Table 5-1 Sequence of operation Name Timing Purpose WAIT From power-on or the door is closed until the end of the main motor initial drive. Detects presence of a print cartridge. STBY (standby) From the end of the WAIT or LSTR period until either a print command is sent from the formatter or the power is turned off. Prepares the product to receive print commands INTR (initial rotation) From the time the print command is received from the formatter until the fuser reached its targeted temperature. Starts each high-voltage biases, the laser scanner, and fuser in preparation for printing. PRINT From the end of the INTR period until the last media completes the fusing operation. Forms the image on the photosensitive drum and transfers the toner image to the media. LSTR (last rotation) From the end of the PRINT period (when high-voltage is turned off) until the main motor stops rotating. Delivers the last page of a print job. After LSTR, the product either returns to STBY or, if another print command was sent from the formatter, enters INTR. ENWW Timing 83 Engine control system The engine control system coordinates all product functions, according to commands sent from the formatter. It drives the laser/scanner system, the image-formation system, and the pickup/feed/delivery system.

The DC controller identifies the laser/scanner unit failure and notifies the formatter if the laser/scanner unit encounters the following conditions: ENWW ● Scanner motor failure ● BD failure Laser/scanner system 89 Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Each process functions independently and must be coordinated with the other product processes. Image formation consists of the following five processes: ● electrostatic latent-image formation ● developing ● transfer ● fusing ● drum cleaning The five processes contain seven steps. Figure 5-8 Image-formation system Media path Direction of the drum rotation Latent image formation 2. Laser-beam exposure Block Step 1. Primary charging Developing 3. Developing Drum cleaning Delivery 6. Fusing Fusing 7. Drum cleaning 5. Separation 4. Transfer Pickup Transfer Step 1: Primary charging DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum. Figure 5-9 Primary charging Primary charging roller Primary charging bias Photosensitive drum 90 Chapter 5 Theory of operation ENWW Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized. Laser beam Unexposed area Exposed area Step 3: Developing The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image. NOTE: The charges on the exposed area of the drum are shown as positive in Figure 5-10 Developing on page 91. The charges are actually negative, but they are more positive than the charges on the developing cylinder. Figure 5-10 Developing Blade Developing roller Exposed area Unexposed area Unexposed area Exposed area Developing bias Photosensitive drum Toner acquires a negative charge through friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image. The image on the drum becomes visible because of the toner. Step 4: Transfer The transfer charging roller, to which a dc positive bias is applied, imparts a positive charge on the print media. When the print media comes in contact with the photosensitive drum, the toner is transferred to the print media. ENWW Image-formation system 91 Figure 5-11 Transfer Photosensitive drum Media Transfer roller Transfer bias Step 5: Separation The elasticity of the print media causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion. Figure 5-12 Separation Photosensitive drum Media Static charge eliminator Transfer roller Step 6: Fusing The dc negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering. 92 Chapter 5 Theory of operation ENWW Figure 5-13 Fusing Fusing heater Fusing film Toner Media Pressure roller Fusing bias Step 7: Drum cleaning The cleaning blade scrapes the residual toner off the photosensitive drum and deposits it into the waste toner case. Figure 5-14 Drum cleaning Cleaning blade Toner collection box ENWW Photosensitive drum Image-formation system 93 Pickup/feed/delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The DC controller uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the product. If media does not reach or pass each sensor within a specified period, the DC controller determines that a jam has occurred and alerts the formatter.

NOTE: Your product might not appear exactly as the one shown in the photos in this chapter. For example, the color of the external panels and covers might be different than your product. However, the procedures in this chapter are valid for both the HP LaserJet P2035 and the HP LaserJet P2055. Replacing FRUs is generally the reverse of removal. Notes and tips are included to provide directions for difficult or critical replacement procedures. HP does not support repairing individual subassemblies or troubleshooting to the component level. Note the length, diameter, color, type, and placement of each screw. Be sure to return each screw to its original location during reassembly. Incorrectly routed or loose wire harnesses can interfere with other internal components and can become damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides. Removal and replacement strategy WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before attempting to service the product. If this warning is not followed, severe injury can result, in addition to damage to the product. The power must be on for certain functional checks during problem solving. However, the power supply should be disconnected during parts removal. Never operate or service the product with the protective cover removed from the laser/scanner assembly. The reflected beam, although invisible, can damage your eyes. The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts. CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do not straighten pre-folds in the FFCs. You must Make sure that all FFCs are fully seated in their connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA. NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly. Electrostatic discharge CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when removing product parts. Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part. Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product. 98 Chapter 6 Removal and replacement ENWW Required tools ● #2 Phillips screwdriver with a magnetic tip and a 152-mm (6-inch) shaft length ● Small flatblade screwdriver ● Needle-nose pliers ● ESD mat (if one is available) or ESD strap ● Penlight (optional) CAUTION: Always use a Phillips screwdriver (callout 1).

If the product does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the problem, you can stop without performing the other steps on the checklist. Troubleshooting checklist 1. 2. Make sure the product Ready light is on. If no lights are on, complete these steps: a. Check the power-cable connections. b. Check that the power switch is on. c. Make sure that the line voltage is correct for the product power configuration. (See the label that is on the back of the product for voltage requirements.) If you are using a power strip and its voltage is not within specifications, plug the product directly into the wall. If it is already plugged into the wall, try a different outlet. d. Verify that connectors J2 and J7 on the formatter PCA are seated. See Figure 7-3 Components on the left side of the product on page 196. e. Perform an engine test. If the test is successful, replace the control panel and then the formatter PCA. See Top-cover assembly on page 124, Formatter PCA; HP LaserJet P2030 Series on page 130, or Formatter PCA; HP LaserJet P2050 Series on page 132. Check the cables. a. Check the cable connection between the product and the computer or network port. Make sure that the connection is secure. b. Make sure that the cable itself is not faulty by using a different cable, if possible. c. Check the network connection. See Solve network problems on page 249. 3. Check to see if any messages appear on the control-panel display. If any error messages appear, see Interpret control-panel messages (HP LaserJet P2050 Series Printers only) on page 219. 4. Check to see if any control-panel lights are lit. See Status-light patterns (HP LaserJet P2030 Series Printers only) on page 209. 5. Make sure that the print media that you are using meets specifications. 6. Print a configuration page. See Print the information pages on page 48. 7. a. If the pages do not print, check that at least one tray contains print media. b. If the page jams in the product, see Clear jams on page 230. If the configuration page prints, check the following items. If the page prints correctly, then the product hardware is working. The problem is with the computer that you are using, with the printer driver, or with the program. 8. Select one of the following options: Windows: Click Start, click Settings, and then click Printers, or Printers and Faxes. Doubleclick the name of the product. 186 Chapter 7 Solve problems ENWW -orMac OS X: Open Print Center or Printer Setup Utility, and double-click the line for the product. 9. Verify that you have installed the printer driver for this product. Check the program to make sure that you are using the printer driver for this product. 10. Print a short document from a different program that has worked in the past. If this solution works, then the problem is with the program that you are using. If this solution does not work (the document does not print), complete these steps: a. Try printing the job from another computer that has the product software installed. b. If you connected the product to the network, connect the product directly to a computer with a USB cable. Redirect the product to the correct port, or reinstall the software, selecting the new connection type that you are using. Factors that affect product performance Several factors affect the time it takes to print a job: ● Maximum product speed, measured in pages per minute (ppm) ● The use of special paper (such as transparencies, heavy paper, and custom-size paper) ● Product processing and download time ● The complexity and size of graphics ● The speed of the computer you are using ● The USB connection ● The product I/O configuration ● The amount of memory installed in the product ● The network operating system and configuration (if applicable) NOTE: Although additional memory can improve how the product handles complex graphics and improve download times, it will not increase maximum product speed (ppm).

This chapter contains information to help diagnose and solve problems. ● Use the pre-troubleshooting checklist to evaluate the source of the problem and to reduce the number of steps that are required to fix the problem. ● Use the troubleshooting flowchart to pinpoint the root cause of hardware malfunctions. The flowchart guides you to the appropriate section of this chapter that provides steps for correcting the malfunction. Before beginning any troubleshooting procedure, check the following conditions: ● Are supply items within their rated life? ● Does the configuration page reveal any configuration errors? NOTE: The customer is responsible for checking supplies and for using supplies that are in good condition. Pre-troubleshooting checklist The following table includes basic questions to ask the customer to quickly help define the problem or problems. General topic Questions Environment ● Is the product installed on a solid, level surface (+/- 1°)? ● Is the power-supply voltage within ± 10 volts of the specified power source? ● Is the power-supply plug inserted in the product and the outlet? ● Is the operating environment within the specified parameters? ● Is the product exposed to ammonia gas, such as that produced by diazo copiers or office cleaning materials? NOTE: Diazo copiers produce ammonia gas as part of the coping processes. Ammonia gas (from cleaning supplies or a diazo copier) can have an adverse affect on some product components (for example, the print-cartridge OPC). ● Is the product exposed to direct sunlight? ● Does the customer use only supported media? ● Is the media in good condition (no curls, folds, or distortion)? ● Is the media stored correctly and within environmental limits? ● Is the amount of media in the tray within specifications? ● Is the media placed in the tray correctly? ● Are the paper guides aligned with the media? ● Is the cassette correctly installed in the product? Print cartridges ● Is each print cartridge correctly installed? Transfer unit and fuser ● Are the transfer unit and fuser installed correctly? Media Input trays ENWW Troubleshooting process 191 General topic Questions Covers ● Is the front cover closed? Condensation ● Does condensation occur following a temperature change (particularly in winter following cold storage)? If so, wipe affected area dry or leave the product on for 10 to 20 minutes. ● Was a print cartridge installed soon after being moved from a cold to a warm room? If so, allow the print cartridge to sit at room temperature for 1 to 2 hours. ● Check for and remove any non-HP components (print cartridges, memory modules, and EIO cards) from the product. ● Remove the product from the network and make sure that the failure is associated with the product before beginning troubleshooting. ● For any print-quality issues, calibrate the product. Miscellaneous 192 Chapter 7 Solve problems ENWW Tools for troubleshooting The section describes the tools that can help you solve problems with your device. Continuous self-test (HP LaserJet P2050 Series only) The continuous self-test puts the device into a continuous printing mode without having to send jobs to it. 1. Confirm that the product is in a Ready state. Press OK to enter the main menu. 2. Simultaneously press and hold the down arrow 3. Press OK to re-enter the main menu. 4. Navigate to the secondary service menu. 5. Select Service Reports and then Cont. Self-Test. and Cancel button To terminate the continuous self-test, press the Cancel button . . Half self-test functional check The half self-test check determines which printing process is malfunctioning. 1. Print a Configuration page. 2. Press the print-cartridge-door button after the paper advances halfway through the product (about five seconds after the motor begins rotating). The leading edge of the paper should have advanced past the print cartridge. 3. Remove the print cartridge. 4. Open the print cartridge drum shield to view the drum surface. If a dark and distinct toner image is present on the drum surface, assume that the first two functions of the electrophotographic process are functioning (image formation and development). Troubleshoot the failure as a transfer or fusing problem. If there is no image on the photosensitive drum, perform these checks: 1. Make sure you removed the entire length of the sealing tape from the print cartridge before you installed the cartridge. 2. Perform a drum rotation functional check to make sure that the drum is rotating. 3. Perform a high-voltage contacts check. Drum rotation functional check The photosensitive drum, located in the print cartridge, must rotate for the print process to work. The photosensitive drum receives its drive from the main drive assembly. NOTE: ENWW This test is especially important if refilled print cartridges have been used. 1. Open the print-cartridge door. 2. Remove the print cartridge. Tools for troubleshooting 193 3. Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark. 4. Replace the print cartridge and close the print-cartridge door. The startup sequence should rotate the drum enough to move the mark. 5. Open the print-cartridge door and inspect the gear that was marked in step 3. Verify that the mark moved. If the mark did not move, inspect the main drive assembly to make sure that it is meshing with the print cartridge gears. If the drive gears appear functional and the drum does not move, replace the print cartridge. See Print cartridge on page 102. Heating element check Paper passes between the heating element and a soft pressure roller to fuse toner to the paper. 1. Unplug the product for at least ten minutes. 2. Verify that the thermistor connector is seated into both the product chassis and the ECU. 3. Remove the heating element connector from the ECU. To measure the continuity of the heating element, measure the resistance between the two pins at the end of the cable. NOTE: Normal resistance is 25 ohms +/- 10 ohms for the 110 V product and 80 ohms +/- 20 ohms for the 220 V product. If no resistance is measured, replace the fuser. See Fuser on page 158. 4. Remove the thermistor connector, and then measure the resistance between J206 pins one and two and between J206 pins three and four. NOTE: Normal resistance between both pairs of pins is 370K ohms +/- 50K ohms at 20° C (68° F). 5. If no resistance is measured, replace the fuser. See Fuser on page 158, High-voltage contacts check The high-voltage contacts in the product must have a good connection with the contacts on the print cartridge to provide the necessary voltages for the electrophotographic processes. Checking the print cartridge contacts When the product is turned on, high voltage is placed on the developer roller of the print cartridge. If the antenna does not detect this voltage, the product displays an Install Black Cartridge message. Remove the print cartridge and visually inspect the three connection points on the ends of the print cartridge: primary charging contact (callout 1), developer roller contact (callout 2), and antenna contact (callout 3). 194 Chapter 7 Solve problems ENWW If one is dirty or corroded, clean the connection with isopropyl alcohol. If one is damaged, replace the print cartridge. See Print cartridge on page 102.

The product is jammed.1 Cause Solution The paper does not meet specifications. Use only paper that meets HP specifications. See Supported paper and print media on page 32. A component is installed incorrectly. Verify that the print cartridge is correctly installed. You are using paper that has already passed through a product or copier. Do not use paper that has been previously printed on or copied. A tray is loaded incorrectly. Remove any excess paper from the tray. Make sure that the stack is below the maximum stack height mark in the tray. See Load trays on page 38. The paper is skewed. The tray guides are not adjusted correctly. Adjust them so they hold the stack firmly in place without bending it. The paper is binding or sticking together. Remove the paper, flex it, rotate it 180°, or flip it over. Reload the paper into the tray. NOTE: Do not fan paper. Fanning can create static electricity, which can cause paper to stick together. The paper is removed before it settles into the output bin. Reset the product. Wait until the page completely settles in the output bin before removing it. During two-sided printing, you removed the paper before the second side of the document was printed. Reset the product and print the document again. Wait until the page completely settles in the output bin before removing it. The paper is in poor condition. Replace the paper. The internal rollers from the tray are not picking up the paper. Remove the top sheet of paper. If the paper is too heavy, it might not be picked from the tray. 1 ENWW The paper has rough or jagged edges. Replace the paper. The paper is perforated or embossed.

In your printer driver, make sure the appropriate media type is selected. ● Try installing a new HP print cartridge. ● The fuser temperature might be too low. In your printer driver, make sure the appropriate media type is selected. ● Clean the inside of the printer. ● Check the media type and quality. ● In your printer driver, make sure the appropriate media type is selected. ● Plug the printer directly into an AC outlet instead of into a power strip. ● The print cartridge might be damaged. If a repetitive mark occurs at the same spot on the page, install a new HP print cartridge. ● The internal parts might have toner on them. If the defects occur on the back of the page, the problem will probably correct itself after a few more printed pages. ● In your printer driver, make sure the appropriate media type is selected. ● If characters are improperly formed, producing hollow images, the media stock might be too slick. Try a different media. ● If characters are improperly formed, producing a wavy effect, the printer might need service. Print a configuration page. If the characters are improperly formed, contact an HP-authorized dealer or service representative. Loose toner Vertical repetitive defects Misformed characters 244 Chapter 7 Solve problems ENWW Page skew ● Make sure that the media is loaded correctly and the media guides are not too tight or too loose against the media stack. ● The input bin might be too full. ● Check the media type and quality. ● Check the media type and quality. Both high temperature and high humidity cause media to curl. ● The media might have been in the input tray too long. Turn over the stack of media in the tray. Also, try rotating the media 180° in the input tray. ● Open the straight-through output door and try printing straight through. ● The fuser temperature might be too high. In your printer driver, make sure the appropriate media type is selected. If the problem persists, select a media type that uses a lower fuser temperature, such as transparencies or light media. ● Make sure that media is loaded properly. ● Check the media type and quality. ● Open the straight-through output door and try printing straight through. ● Turn over the stack of media in the tray. Also, try rotating the media 180° in the input tray. ● For envelopes, this can be caused by air pockets inside the envelope. Remove the envelope, flatten the envelope, and try printing again. Curl or wave Wrinkles or creases ENWW Solve image-quality problems 245 Toner scatter outline 246 Chapter 7 Solve problems ● If large amounts of toner have scattered around the characters, the media might be resisting the toner. (A small amount of toner scatter is normal for laser printing.) Try a different media type. ● Turn over the stack of media in the tray. ● Use media that is designed for laser printers. ENWW Solve print-quality problems You can prevent most print-quality problems by following these guidelines. ● Configure the trays for the correct paper-type setting. See Configure trays (HP LaserJet P2050 Series Printers only) on page 43. ● Use paper that meets HP specifications. See Supported paper and print media on page 32. ● Clean the product as necessary. See Clean the paper path (HP LaserJet P2050 Series Printers only) on page 70. Print-quality problems associated with paper Some print-quality problems arise from using paper that does not meet HP specifications. ● The surface of the paper is too smooth. ● The moisture content of the paper is uneven, too high, or too low. Use paper from a different source or from an unopened ream. ● Some areas of the paper reject toner. Use paper from a different source or from an unopened ream. ● The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this solves your problem, ask the supplier of your letterhead to use paper that meets HP specifications. ● The paper is excessively rough. Use a smoother, xerographic paper. ● The paper is too heavy for the paper-type setting that you selected, so the toner is not fusing to the paper. For complete paper specifications for all HP LaserJet products, see the HP LaserJet Printer Family Print Media Guide. This guide is available at www.hp.com/support/ljpaperguide. Print-quality problems associated with the environment If the product is operating in excessively humid or dry conditions, verify that the printing environment is within specifications. See Operating environment on page 293. Print-quality problems associated with jams Make sure that all sheets are cleared from the paper path. ENWW ● If the product recently jammed, print two to three pages to clean the paper path. ● If the sheets do not pass through the fuser and cause image defects on subsequent documents, print two to three pages to clean the paper path. If the problem persists, print and process a cleaning page. See Clean the paper path (HP LaserJet P2050 Series Printers only) on page 70. Solve print-quality problems 247 Solve performance problems Problem Cause Solution Pages print but are totally blank. The sealing tape might still be in the print cartridges. Verify that the sealing tape has been completely removed from the print cartridges. The document might contain blank pages. Check the document that you are printing to see if content appears on all of the pages. The product might be malfunctioning. To check the product, print a Configuration page. Heavier paper types can slow the print job. Print on a different type of paper. Complex pages can print slowly. Proper fusing may require a slower print speed to ensure the best print quality. The product might not be pulling paper correctly. Make sure paper is loaded in the tray correctly. The paper is jamming in the product. Clear the jam. See Jams on page 229. The USB cable might be defective or incorrectly connected. ● Disconnect the USB cable at both ends and reconnect it. ● Try printing a job that has printed in the past. ● Try using a different USB cable. Pages print very slowly. Pages did not print. Other devices are running on your computer. 248 Chapter 7 Solve problems The product might not share a USB port. If you have an external hard drive or network switchbox that is connected to the same port as the product, the other device might be interfering. To connect and use the product, you must disconnect the other device or you must use two USB ports on the computer. ENWW Solve connectivity problems Solve direct-connect problems If you have connected the product directly to a computer, check the cable. ● Verify that the cable is connected to the computer and to the product. ● Verify that the cable is not longer than 2 meters (6 feet). Replace the cable if necessary. ● Verify that the cable is working correctly by connecting it to another product. Replace the cable if necessary. Solve network problems Check the following items to verify that the product is communicating with the network. Before beginning, print a configuration page. See Print the information pages on page 48. 1. Are there any physical connection problems between the workstation or file server and the product? Verify that the network cables, connections, and router configurations are correct. Verify that the network cable lengths meet network specifications. 2. Are the network cables connected properly? Make sure that the product is attached to the network using the appropriate port and cable. Check each cable connection to make sure that it is secure and in the right place. If the problem continues, try a different cable or ports on the hub or transceiver. The amber activity light and the green link status light next to the port connection on the back of the product should be lit. 3. Are the product link speed and duplex settings set correctly? Hewlett-Packard recommends leaving this setting in automatic mode (the default setting). 4. Can you "ping" the product? Use the command prompt to ping the product from the computer. For example: ping 192.168.45.39 Make sure that the ping displays round-trip times. If you are able to ping the product, verify that the IP address configuration for the product is correct on the computer. If it is correct, delete and then add the product again. If the ping command failed, verify that the network hubs are on, and then verify that the network settings, the product, and the computer are all configured for the same network. 5. Have any software programs been added to the network? Make sure they are compatible and that they are installed correctly with the correct printer drivers. 6. Are other users able to print? The problem might be workstation-specific. Check the workstation network drivers, printer drivers, and redirection (capture in Novell NetWare). 7. ENWW If other users are able to print, are they using the same network operating system? Solve connectivity problems 249 Check your system for proper network operating system setup. 8.

Rev. 11/06 ENWW End User License Agreement 285 Customer self-repair warranty service HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and allow for greater flexibility in performing defective parts replacement. If during the diagnosis period, HP identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for replacement. There are two categories of CSR parts: 1) Parts for which customer self repair is mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs of this service. 2) Parts for which customer self repair is optional. These parts are also designed for Customer Self Repair. If, however, you require that HP replace them for you, this may be done at no additional charge under the type of warranty service designated for your product. Based on availability and where geography permits, CSR parts will be shipped for next business day delivery. Same-day or four-hour delivery may be offered at an additional charge where geography permits. If assistance is required, you can call the HP Technical Support Center and a technician will help you over the phone. HP specifies in the materials shipped with a replacement CSR part whether a defective part must be returned to HP. In cases where it is required to return the defective part to HP, you must ship the defective part back to HP within a defined period of time, normally five (5) business days. The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to be used. 286 Appendix A Service and support ENWW Customer support Get telephone support, free during your warranty period, for your country/region Country/region phone numbers are on the flyer that was in the box with your product or at www.hp.com/support/.

On-site service agreements To provide you with the level of support best suited to your needs, HP has on-site service agreements with a selection of response times. Next-day on-site service This agreement provides support by the next working day following a service request. Extended coverage hours and extended travel beyond HP’s designated service zones are available on most onsite agreements (for additional charges). Weekly (volume) on-site service This agreement provides scheduled weekly on-site visits for organizations with many HP products. This agreement is designated for sites using 25 or more workstation products, including devices, plotters, computers, and disk drives. Repack the product If HP Customer Care determines that your product needs to be returned to HP for repair, follow these steps to repack the product before shipping it. CAUTION: Shipping damage as a result of inadequate packing is the customer’s responsibility. 1. Remove and retain any DIMMs cards that you have purchased and installed in the device. Do not remove the DIMM that came with the device. CAUTION: Static electricity can damage DIMMs. When handling DIMMs, either wear an antistatic wrist strap, or frequently touch the surface of the DIMM antistatic package and then touch bare metal on the device. To remove the DIMMs, see Install memory (HP LaserJet P2050 Series Printers only) on page 64. 2. Remove and retain the print cartridge. CAUTION: It is extremely important to remove the print cartridge before shipping the product. A print cartridge that remains in the product during shipping can leak and cover the product engine and other parts with toner. To prevent damage to the print cartridge, avoid touching the roller on it, and store the print cartridge in its original packing material or so that it is not exposed to light. 3. Remove and retain the power cable, interface cable, and optional accessories. 4. If possible, include print samples and 50 to 100 sheets of paper or other print media that did not print correctly. 5. In the U.S., call HP Customer Care to request new packing material. In other areas, use the original packing material, if possible. Hewlett-Packard recommends insuring the equipment for shipment. 288 Appendix A Service and support ENWW Extended warranty HP Support provides coverage for the HP hardware product and all HP-supplied internal components.
