Supplies life The average cartridge yield is 6,500 pages (for the Q7551A cartridge) or 13,000 pages (for the Q7551X cartridge), in accordance with ISO/IEC 19752. Actual cartridge yield depends on specific use. CAUTION EconoMode is a feature that allows the device to use less toner per page. Selecting this option may extend the life of the toner supply and may reduce cost per page. However, it will also reduce 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 will outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these circumstances, you will need to install a new print cartridge, even if there may be toner supply remaining in the cartridge. Approximate print-cartridge replacement intervals Print cartridge Page count Approximate time period1 Black (Q7551A) 6,500 pages1 3 months Black (Q7551X) 13,000 pages 6 months Approximate life is based on 2,000 pages per month.

Print-cartridge authentication The device automatically authenticates the print cartridge when it is inserted into the device. During authentication, the device notifies you whether a cartridge is a genuine HP print cartridge. If the device control-panel message states that this is not a genuine HP print cartridge and you believe you purchased an HP print cartridge, see HP fraud hotline and Web site on page 35. HP fraud hotline and Web site Call the HP fraud hotline (1-877-219-3183, toll-free in North America) or go to www.hp.com/go/ anticounterfeit when you install an HP print cartridge and the control-panel message says the cartridge is non-HP. HP will help determine if the cartridge is genuine and take steps to resolve the problem. Your print cartridge might not be a genuine HP print cartridge if you notice the following: ENWW ● You are experiencing a high number of problems with the print cartridge. ● The cartridge does not look like it usually does (for example, the orange pull tab is missing, or the packaging differs from HP packaging). Manage supplies 35 Clean the device Over time, particles of toner and paper accumulate inside the device. This can cause print-quality problems during printing. Cleaning the device eliminates or reduces these problems. Clean the paper path and print-cartridge areas every time that you change the print cartridge or whenever print-quality problems occur.

The following systems are discussed: ● Formatter ● Engine control unit ● Laser/scanner system ● Pickup/feed/delivery system ● Image-formation system Figure 4-1 Systems overview Formatter The formatter is responsible for the following actions: 46 ● Formatting and controlling copies ● Receiving and processing print data from the computer interface ● Monitoring the control panel and relaying device status information ● Developing and coordinating data placement and timing with the print engine Chapter 4 Theory of operation ENWW Engine control unit (ECU) The ECU coordinates all device functions, according to commands that the formatter sends. It drives the laser/scanner system, the image formation system, and the pickup/feed/delivery system. The ECU contains the following components: ● Engine controller PCA ● Low-voltage PCA Figure 4-2 Print engine general structure on page 47 shows the relationship of the ECU to the pickup/ feed/delivery system, the laser/scanner system, and the image-formation system.

The ECU uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the device. If media does not reach or pass each sensor within a specified time period, the ECU determines that a jam has occurred and alerts the formatter. The following components are identified in Figure 4-5 Pickup/feed/delivery system on page 50: ● M1, main motor ● PS3, tray 2 media-detection sensor ● M2, fuser motor ● PS901, top-of-page sensor ● SL1, tray 1 pickup solenoid ● PS902, tray 1 media-detection sensor ● SL2, tray 2 pickup solenoid ● SR1, top output-bin delivery flag ● PS2, duplexer media-detection sensor ● SR2, fuser-delivery flag Figure 4-5 Pickup/feed/delivery system 50 Chapter 4 Theory of operation ENWW Laser/scanner system The laser/scanner system receives video signals from the ECU and the formatter and converts the signals into latent images on the photosensitive drum. Figure 4-6 Laser/scanner system ENWW Basic operation 51 Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Figure 4-7 Print cartridge diagram Each process functions independently and must be coordinated with the other device processes. Image formation consists of the following five processes: ● Electrostatic latent-image formation ● Developing ● Transfer ● Fusing ● Drum cleaning The five processes contain eight steps, which are shown in Figure 4-8 Image-formation system on page 52 and described in the following sections. Figure 4-8 Image-formation system 52 Chapter 4 Theory of operation ENWW 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 4-9 Primary charging 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. 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 4-10 Developing on page 53. The charges are actually negative, but they are more positive than the charges on the developing cylinder. Figure 4-10 Developing ENWW Basic operation 53 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. Photosensitive drum Media Transfer roller Figure 4-11 Transfer 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 4-12 Separation 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. 54 Chapter 4 Theory of operation ENWW Figure 4-13 Fusing Step 7: Drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case.

The cartridge usage condition is detected as the engine controller reads or writes the data stored on the memory tag. The engine controller renews the information in the prescribed timing and reads or writes it from or to the memory tag. The engine controller commands the memory tag to read or write with the following conditions: ● ● Read ● Power is on. ● The cartridge door is closed. ● A command has been received from the formatter. Write ● A page of media is printed. ● A command has been received from the formatter. When the engine controller fails to read or write three times in a row, it determines that the memory tag is abnormal and sends a cartridge memory abnormality warning to the formatter.

Isolate the problem to the major system (for example, the network or server, or the device). 2. Troubleshoot the problem by using the procedures in chapter 6. After you locate a faulty part, the device can usually be repaired at the assembly level by replacing fieldreplaceable units (FRUs). Some mechanical assemblies might need to be repaired at the subassembly level. Hewlett-Packard Company does not support replacement of components on the printed circuit assembles. Before performing service Follow the pre-service procedures before you perform service. Pre-service procedures ENWW 1. Remove all media from the device. 2. Unplug the power cord and the interface cable. 3. Lift the device off of any installed optional trays. 4. Remove the print cartridge. 5. Remove tray 2. 6. Place the device on an ESD mat. If an ESD mat or an ESD-protected workstation is not available, discharge body static and ground the device chassis before servicing the device.

Verify that the device 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 main fan runs briefly. 4. ● If the control-panel display is blank, but the main fan runs briefly after the power is turned on, print an engine test page (see Engine-test page on page 165) to determine whether the problem is with the control-panel display, the formatter, or other components. ● If the main fan does not run, check the ECU connections. If necessary, replace the ECU. See Engine control unit (ECU) on page 88. Remove any HP Jetdirect or other EIO cards, and then turn off and turn on the device. 130 Chapter 6 Troubleshooting ENWW Control-panel messages Control-panel message types Four types of control-panel messages can indicate the status of or problems with the device. Message type Description Status messages Status messages reflect the current state of the device. They inform you of normal device operation and require no interaction to clear them. They change as the state of the device changes. Whenever the device is ready, not busy, and has no pending warning messages, the status message Ready appears if the device is online. Warning messages Warning messages inform you of data and print errors. These messages typically alternate with the Ready or status messages and remain until you touch OK. Some warning messages are clearable. If CLEARABLE WARNINGS is set to JOB on the device DEVICE BEHAVIOR menu, the next print job clears these messages. Error messages Error messages communicate that some action must be performed, such as adding paper or clearing a jam. Some error messages are auto-continuable. If AUTO CONTINUE is set on the menus, the device will continue normal operation after an auto-continuable error message appears for 10 seconds. NOTE Pressing any button during the 10-second auto-continuable error message overrides the auto-continue feature, and the button function takes precedence. For example, pressing the Stop button pauses printing and offers the option to cancel the print job. Critical-error messages Critical error messages inform you of a device failure. Some of these messages can be cleared by turning the device off and then on. These messages are not affected by the AUTO CONTINUE setting. If a critical error persists, service is required.
