● Formatter-control system ● Engine-control system ● Image-formation system ● Pickup, feed, and delivery system ● Main-input tray or priority input slot 1 Basic operation Major product systems The product contains the following major systems: ● Engine-control system ● Laser/scanner system ● Image-formation system ● Pickup-and-feed system Product block diagram Figure 1-1 Product block diagram LASER/SCANNER SYSTEM ENGINE CONTROL SYSTEM IMAGE-FORMATION SYSTEM PICKUP-AND-FEED SYSTEM 2 Chapter 1 Theory of operation ENWW Sequence of operation The DC controller in the engine-control system controls the operational sequences of the product. The table below describes durations and operations for each period of a print operation from when the product is turned on until the motor stops rotating. Normal sequence of operation Table 1-1 Sequence of operation Name Timing Purpose WAIT From the time the power switch is turned on, the door is closed or the product exits Sleep mode until the product gets ready for a print operation. Brings the product to ready state. The product performs the following during the operations: STBY (standby) INTR (initial rotation) From the end of the WAIT or LSTR period until either a print command is sent or the power switch is turned off. From the time a print command is received until the paper is picked up. ● Detects the print cartridge ● Heats the fuser film in the fuser ● Rotates, and the stops, the main motor Maintains the product in printable condition. The product performs the following during the operation: ● Enters Auto-Off mode if Auto-Off command is received The product performs the following during the operations: ● Drives the main motor ● Activates the high-voltage power supply ● Activates the laser/scanner ● Warms the fuser heater PRINT From the end of the INTR period until the last sheet completes the fuser operation. Forms the image on the photosensitive drum based on the VIDEO signals from the formatter. Transfers and fuses the toner image to the paper. LSTR (last rotation) From the end of the PRINT period until the main motor stops rotating. Moves the last printed sheet out of the product. The product performs the following during the operations: ● Stops the main motor ● Deactivates the high-voltage power supply ● Deactivates the laser/scanner ● Deactivates the fuser heater The product enters the INTR period as the LSTR period is completed, if the formatter sends another print command. ENWW Basic operation 3 Formatter-control system The formatter is responsible for the following procedures: ● Controlling sleep mode ● Receiving and processing print data from the various product interfaces ● Monitoring control-panel functions and relaying product-status information (through the control panel and the network or bidirectional interface) ● Developing and coordinating data placement and timing with the DC controller PCA ● Storing font information ● Communicating with the host computer through the network or the bidirectional interface The formatter receives a print job from the network or bidirectional interface and separates it into image information and instructions that control the printing process. The DC controller PCA synchronizes the image-formation system with the paper-input and -output systems, and then signals the formatter to send the print-image data. Sleep mode NOTE: This product uses an Auto-Off feature for sleep mode. After a user-specified time, the Auto-Off feature automatically conserves electricity by substantially reducing power consumption when the product is not printing. After a user-specified time, the product automatically reduces its power consumption (Auto-Off). The product returns to the ready state when a button is pressed, a print job is received, or a door is opened. When the product is in Auto-Off mode, all of the control-panel LEDs and the power button backlight LED are off. NOTE: Although the product lights are off in Auto-Off mode, the product functions normally when it receives a print job. Input/output The product receives print data primarily from the following: ● Hi-Speed USB 2.0 port ● 802.11b/g wireless networking (wireless models only) CPU The formatter incorporates a 400 MHz Helium processor. Memory The random access memory (RAM) on the formatter PCA contains the page, I/O buffers, and the font storage area. RAM stores printing and font information received from the host system, and can also serve to temporarily store a full page of print-image data before the data is sent to the print engine. 4 Chapter 1 Theory of operation ENWW Firmware ● HP LaserJet Professional P1560 Printer series ◦ ● The product has 8 MB of Synchronous DRAM, which is used for run-time firmware imaging and specific print job information for the print job. HP LaserJet Professional P1600 Printer series ◦ The product has 32 MB of Synchronous DRAM, which is used for run-time firmware imaging and specific print job information for the print job. Memory use ● HP LaserJet Professional P1560 Printer series ◦ ● The product has a 2 KB EEPROM and 64 MB of NAND Flash Memory, which is used for product configuration information and printer driver firmware. HP LaserJet Professional P1600 Printer series ◦ The product has a 8 KB EEPROM and 64 MB of NAND Flash Memory, which is used for product configuration information and printer driver firmware. PJL overview The printer job language (PJL) is an integral part of configuration, in addition to the standard printer command language (PCL). With standard cabling, the product can use PJL to perform a variety of functions such as these: ● Two-way communication with the host computer through a network connection or a USB connection. The product can inform the host about such things as the control-panel settings, and the control-panel settings can be changed from the host. ● Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O. The product can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur even when the product is offline. ● Context-sensitive switching. The product can automatically recognize the personality (PS or PCL) of each job and configure itself to serve that personality. ● Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the product in landscape mode, the subsequent print jobs print in landscape mode only if they are formatted for landscape printing. LEDM overview NOTE: HP LaserJet Professional P1600 Printer series The low-end data model (LEDM) provides one consistent data representation method and defines the dynamic and capabilities tickets shared between clients and devices, as well as the access protocol, event, security, and discovery methods. ACL overview The advanced control language (ACL) is a language that supports product control and firmware downloads in printers that support both PJL/PCL and host-based printing. Each sequence of ACL ENWW Formatter-control system 5 commands must be preceded by a unified exit command (UEL) and an @PJL ENTER LANGUAGE=ACL command. The ACL sequence is always followed by a UEL. Any number of commands can be placed between the UELs. The only exception to these rules is the download command. If a firmware download is done, the download command must be the last command in the sequence. It will not be followed by a UEL. The firmware searches for the UEL sequence when parsing commands. However, while downloading binary data such as host-based code or NVRAM data the firmware suspends UEL parsing. To handle hosts that “disappear” during binary sequences, the firmware times out all ACL command sessions. If a timeout occurs during a non-download command sequence, it is treated as the receipt of a UEL. If a timeout occurs during firmware download the product resets. Control panel The formatter sends and receives product status and command data to and from the control-panel PCA. 6 Chapter 1 Theory of operation ENWW Engine-control system The engine-control system coordinates all product functions, according to commands that the formatter sends. The engine-control system drives the laser/scanner system, the image-formation system, and the pickup/feed/delivery system. The engine control system contains the following major components: ● Engine-control unit (ECU) ◦ DC controller ◦ Low-voltage power supply ● High-voltage power supply ● Fuser control Figure 1-2 Engine-control system ENGINE CONTROL SYSTEM DC controller LASER/SCANNER SYSTEM Low-voltage power supply Formatter IMAGE-FORMATION SYSTEM High-voltage power supply MEDIA-FEED SYSTEM Fuser control ENWW Engine-control system 7 Motors, fans, clutches, solenoids, switches, and sensors Figure 1-3 Motors M1 M2 Table 1-2 Motors Item Description Components driven M1 Main motor ● Pickup roller ● Feed roller ● Photosensitive drum ● Developing roller ● Pressure roller ● Delivery roller ● Duplex feed roller ● Scanner mirror M2 8 Scanner motor Chapter 1 Theory of operation ENWW Figure 1-4 Fans FM1 Table 1-3 Fans ENWW Item Description FM1 Main fan Engine-control system 9 Figure 1-5 Solenoids and clutches SL2 SL1 Table 1-4 Solenoids and clutches Item Description SL1 Pickup solenoid SL2 Duplex reverse solenoid NOTE: Duplex models only. 10 Chapter 1 Theory of operation ENWW Figure 1-6 Switches Table 1-5 Switches Item Description SW501 Cartridge-door switch SW502 Power switch; not shown Figure 1-7 Sensors PS702 PS701 PS751 Table 1-6 Sensors ENWW Item Description PS701 Fuser delivery sensor Engine-control system 11 Table 1-6 Sensors (continued) 12 Item Description PS702 Media-width sensor PS751 Top-of-Page (TOP) sensor PS901 Main-motor rotation-number sensor; not shown Chapter 1 Theory of operation ENWW DC controller operations The DC controller controls the operational sequences of the product systems.

The product uses ondemand fusing. The fuser-control circuit consists of the following major components: ● Fuser heater (H1); heats the fusing film ● Thermistor (TH1); detects the fuser temperature (contact type) ● Thermoswitch (TP1); prevents abnormal temperature rise in the fuser (contact type) Figure 1-9 Fuser control circuit Fuser film TH1 TP1 Pressure roller H1 FUSER TEMPERATURE signal FUSER HEATER CONTROL signal Fuser heater control circuit Fuser heater safety circuit DC controller Fuser control Engine controller ENWW Engine-control system 15 Fuser failure detection The DC controller determines a fuser unit failure, releases the relay to interrupt power supply to the fuser heater, and notifies the formatter of a failure state when it encounters the following conditions: ● ● Start up failure ◦ If the main thermistor does not detect a specified temperature during the start up process of the heater in the wait period. ◦ If the main thermistor does not detect a specified temperature during the heater temperature control in the initial rotation period. Abnormal low temperature ◦ ● Abnormal high temperature ◦ ● If the main thermistor detects an abnormal high temperature of the fuser unit. Frequency detection circuit failure ◦ 16 If the main thermistor detects an abnormal low temperature of the fuser unit during the printing operation. If a specified frequency of the FREQUENCY signal is not detected within a specified period after the product is turned on. Chapter 1 Theory of operation ENWW Fuser temperature control The fuser temperature control maintains the temperature of the fuser heater at its targeted temperature. The DC controller monitors the FIXING TEMPERATURE (FSRTH) signals and sends the FIXING HEATER CONTROL (FSRD) signal according to the detected temperature. The fuser heater control circuit controls the fuser heater depending on the signal so that the heater remains at the targeted temperature. Figure 1-10 Fuser-heater control circuit AC input Engine controller Fixing control Frequency detection circuit (220-240V model only) Relay control circuit RL101 DC controller FREQSNS Fuser heater safety circuit RLYD FSRD Fuser heater control circuit FSRTH TP1 TH1 H1 Fuser film unit Pressure roller Fuser unit ENWW Engine-control system 17 Fuser protective function The protective function detects an abnormal temperature rise of the fuser unit and interrupts power supply to the fuser heater. The following three protective components prevent an abnormal temperature rise of the fuser heater: ● DC controller ◦ ● Fuser heater safety circuit ◦ ● The DC controller interrupts power supply to the fuser heater when it detects an abnormal temperature of the fuser heater. The fuser heater safety circuit interrupts power supply to the fuser heater when the detected temperature of the main thermistor is abnormal. Thermoswitch ◦ The contact of the thermal fuse is broken to interrupt power supply to the fuser heater when the thermal fuse detects an abnormal temperature of the fuser heater. Pressure roller cleaning The pressure roller cleaning process is initiated by the formatter. The process removes toner that has accumulated on the pressure roller by transferring it to a sheet of paper. 18 ● The product feeds a sheet of paper after receiving the cleaning command from the formatter. ● Main motor rotation is stopped when the trailing edge of the paper passes through the transfer roller. ● The main motor rotation is repeatedly started and then stopped. The fuser heater is turned on and then off at the same interval as main motor rotation. ● Toner adhered to the pressure roller is fused to the paper. ● The paper is ejected from the product. Chapter 1 Theory of operation ENWW Low-voltage power supply The low-voltage power supply (LVPS) converts ac input voltage to dc voltage. The LVPS has two fuses on the PCA. The LVPS 24 V output is interrupted to the fuser and the high-voltage power supply if the cartridge-door interlock switch (SW501) is in the off position (cover open). WARNING! The product power switch only interrupts dc voltage from the LVPS. The ac voltage is present in the product when the power cord is plugged into a power receptacle and the power switch is in the off position. You must unplug the product power cord before servicing the product.

If an overcurrent or overvoltage condition occurs, the system automatically cuts off the output voltage. If the dc power is not being supplied from the low-voltage power supply, the protective function might be running. In such case, turn off the power switch and unplug the power cord. Do not plug in the power cord or turn on the power switch again until the cause is found. WARNING! If you believe the overcurrent or overvoltage protection circuits have been activated, do not plug in the product power cord or turn on the product power until the cause of the failure is found and corrected. In addition, two fuses in the low-voltage power supply protect against overcurrent. If overcurrent flows into the ac line, the fuses melt and cut off the power distribution. 20 Chapter 1 Theory of operation ENWW High-voltage power supply The high-voltage power supply (HVPS) applies biases to the following components: ● Primary charging roller ● Developing roller ● Transfer roller Figure 1-12 High-voltage power supply Engine controller DC controller High-voltage power supply Primary charging bias circuit To primary charging roller Developing bias circuit To developing roller Cartridge Transfer bias circuit ENWW Photosensitive drum Transfer roller Engine-control system 21 Laser/scanner system The laser/scanner system receives VIDEO signals from the ECU and formatter and converts the signals into latent images on the photosensitive drum. The main components of the laser/scanner are the laser unit and the scanner motor unit. The DC controller sends signals to the laser/scanner to control the functions of these components. Figure 1-13 Laser/scanner system Photosensitive drum BD sensor Laser unit Scanning mirror SCANNER MOTOR CONTROL signal LASER CONTROL signal VIDEO signal BDI signal Scanner motor unit DC controller Engine controller Formatter 22 Chapter 1 Theory of operation ENWW Laser failure detection The DC controller determines an optical unit failure and notifies the formatter, if the laser/scanner encounters the following conditions: ENWW ● The scanner motor does not reach a specified rotation within a specified period of the scanner motor start up. ● The rotation of the scanner motor is out of specified range for a specified period during the scanner motor drive. ● The BD interval is out of a specified value during a print operation. Engine-control system 23 Image-formation system Electrophotographic process The electrophotographic process forms an image on the paper. Following are the major components used in the process: ● Print cartridge ● Transfer roller ● Fuser ● Laser/scanner ● High-voltage power supply The DC controller uses the laser/scanner and HVPS to form the toner image on the photosensitive drum. The image is transferred to the paper and then fused onto the paper. Figure 1-14 Electrophotographic process block diagram (1 of 2) Transfer roller Cartridge Laser scanner High-voltage power supply DC controller Engine controller The DC controller rotates the main motor to drive the following components: 24 ● Photosensitive drum ● Developing drum ● Primary charging roller (follows the rotation of the photosensitive drum) ● Transfer roller (follows the rotation of the photosensitive drum) Chapter 1 Theory of operation ENWW Figure 1-15 Electrophotographic process block diagram (2 of 2) Primary charging roller Developing roller Transfer roller Main motor Cartridge Photosensitive drum DC controller Engine controller ENWW Image-formation system 25 Image formation process Each of the following process function independently and must be coordinated with the other product processes. Image formation consists of the following processes: ● ● Latent-image formation block ◦ Step 1: primary charging ◦ Step 2: laser-beam exposure Developing block ◦ ● ● Transfer block ◦ Step 4: transfer ◦ Step 5: separation Fusing block ◦ ● Step 3: developing Step 6: fusing Drum cleaning block ◦ Step 7: drum cleaning Figure 1-16 Image formation process 26 Chapter 1 Theory of operation ENWW Latent-image formation stage During the latent-image formation stage, the laser/scanner forms an invisible image on the photosensitive drum in the print cartridge. Primary charging Step 1: DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum. Figure 1-17 Primary charging Primary charging roller DC bias Photosensitive drum Laser beam exposure Step 2: The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum surface. An electrostatic latent image is formed on the drum where negative charges were neutralized. Figure 1-18 Laser beam exposure Laser beam Unexposed area ENWW Exposed area Image-formation system 27 Developing stage Print cartridge Step 3: In the print cartridge, the developing cylinder transfers toner onto the electrostatic latent image on the photosensitive drum. Figure 1-19 Print cartridge Blade Developing cylinder Unexposed area Exposed area AC bias Exposed area Unexposed area DC bias Photosensitive drum Toner acquires a negative charge from the friction that occurs when the developing roller rotates against the developing blade. The developing bias is applied to the developing roller to make a potential difference between the developing roller and the photosensitive drum. The negatively charged toner is attracted to the latent image on the photosensitive drum because the drum surface has a higher potential. 28 Chapter 1 Theory of operation ENWW Transfer stage Step 4: The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the paper. When the page comes in contact with the photosensitive drum, the toner is transferred to the paper. Figure 1-20 Transfer Photosensitive drum Media Transfer roller DC bias Step 5: The elasticity of the paper causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion. Figure 1-21 Separation Photosensitive drum Media Static charge eliminator Transfer roller Fusing stage Step 6: The DC negative bias applied to the fusing film strengthens the holding force of the toner on the paper and prevents the toner from scattering. ENWW Image-formation system 29 The product uses an on-demand fuser method. The toner image is permanently affixed to the paper by heat and pressure. Figure 1-22 Fusing Fuser heater Fuser film Toner Media Pressure roller Cleaning stage Step 7: The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case. Figure 1-23 Drum cleaning Cleaning blade Waste toner container 30 Chapter 1 Theory of operation Photosensitive drum ENWW Pickup, feed, and delivery system The media feed system picks up, feeds, and delivers the page.

Replacing FRUs is generally the reverse of removal. Occasionally, 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 location 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 and retainers. 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 troubleshooting. However, disconnect the power supply 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 fully seat all FFCs 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. TIP: For clarity, some photos in this chapter show components removed that would not be removed to service the product. If necessary, remove the components listed at the beginning of a procedure before proceeding to service the product. 36 Chapter 2 Removal and replacement ENWW 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, or use an ESD strap. If an ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part.

See Formatter PCA on page 67 . Solve problems checklist 115 Troubleshooting process Determine the problem source 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 paper? ● Is the paper in good condition (no curls, folds, or distortion)? ● Is the paper stored correctly and within environmental limits? ● Is the amount of paper in the tray within specifications? ● Is the paper correctly placed in the tray? ● Are the paper guides aligned with the stack? Print cartridge ● Is the print cartridge installed correctly? Transfer roller and fuser ● Are the transfer roller and fuser installed correctly? Print-cartridge door and duplex door (duplex models only) ● Is the print-cartridge or duplex door closed? Condensation ● Does condensation occur following a temperature change (particularly in winter following cold storage)? If so, wipe affected parts dry or leave the product on for 10 to 20 minutes. ● Was a print cartridge opened 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 (for example, a print cartridge) from the product. ● Remove the product from the network and make sure that the failure is with the product before beginning troubleshooting. Paper Input trays Miscellaneous 116 Chapter 3 Solve problems ENWW Power subsystem Power-on checks Turn on the power. If the control-panel LEDs do not illuminate, perform the power-on checks to find the cause of the problem. 1. Verify that the product is plugged into an active electrical outlet that delivers the correct voltage. 2. Verify that the power switch is in the on position. 3. Make sure that the product makes the expected start-up sounds. NOTE: The overcurrent/overvoltage protection circuit in the low-voltage power supply unit might be functioning. Turn the product off, unplug the power cord, and turn the product on. If the product does not function, the fuse melts, or the power supply is malfunctioning, replace the engine controller unit. See Engine controller PCA on page 97. ENWW Troubleshooting process 117 Tools for troubleshooting Individual component diagnostics Engine diagnostics Printing test pages helps you determine whether or not the product engine and the formatter are functioning. If the formatter is damaged, it might interfere with the engine test. If the engine-test page does not print, try removing the formatter and then performing the engine test again. If the engine test is then successful, the problem is almost certainly with the formatter. NOTE: Information pages also can be used to solve product issues. For information about printing information pages, see the product user guide. Engine-test button NOTE: The product has a firmware engine-test button that is activated by opening and closing the print-cartridge door in a specific pattern. HP LaserJet Professional P1560 Printer series 1. Make sure that paper is correctly loaded in the tray. 2. Make sure that the output bin tray extension is in the open position. 3. Turn the product on. Wait for the product to reach the ready state. 4. Open, and then close the print-cartridge door six times at an interval of about two seconds to start the engine-test. 5. If the engine test is successful, an engine-test page prints with a series of vertical lines across the page. Figure 3-1 Sample engine test page HP LaserJet Professional P1600 Printer series 1. Make sure that paper is correctly loaded in the tray. 2. Make sure that the output bin tray extension is in the open position. 3. Turn the product on. Wait for the product to reach the ready state. 4. Open, and then close the print-cartridge door five times at an interval of about two seconds to activate the internal engine-test button. 5. If the engine test is successful, an engine-test page prints with a series of vertical lines across the page. 118 Chapter 3 Solve problems ENWW Components tests 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: This test is especially important if refilled print cartridges have been used. 1. Open the print-cartridge door. 2. Remove the print cartridge. 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. Half self-test functional check The half self-test check determines which printing process is malfunctioning. 1. Print a Configuration page. 2. Open the print-cartridge-door 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: ENWW 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. Make sure that the high-voltage contacts are clean and not damaged.

Rev. 11/06 ENWW End User License Agreement 187 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.
