Manage supplies
Using, storing, and monitoring the print cartridge can help ensure high-quality output.
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 period
Black (Q7551A) 6,500 pages
Black (Q7551X) 13,000 pages 6 months

quality.
34 Chapter 3 Maintenance ENWW
NOTE Any damage caused by a non-HP print cartridge is not covered under the HP warranty
and service agreements.
To install a new HP print cartridge, see Change the print cartridge on page 23. To recycle the used
cartridge, follow the instructions included with the new cartridge.
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

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:
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).

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. As much as possible, keep the device from dust and debris.
Clean the exterior

Clean spilled toner
If you get any toner on your clothes or hands, wash them in cold water. Hot water will set the toner into
the fabric.
Clean the fuser
Run the device cleaning page to keep the fuser free of toner and paper particles that can sometimes
accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side
of your print jobs.
To ensure optimum print quality, HP recommends that you use the cleaning page every time that you
replace the print cartridge.
The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the
device control panel display while the cleaning is taking place.
In order for the cleaning page to work correctly, print the page on copier-grade paper (not bond, heavy,
or rough paper).

The pickup/feed/delivery system consists of several types of feed rollers and sensors. 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.

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.

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
on page 52 and described in the following sections.
Figure 4-8 Image-formation system
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.
Figure 4-11 Transfer
Photo-
sensitive
drum
Transfer roller
Media
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.

Print cartridge memory system
The memory tag is a nonvolatile memory built into the print cartridge. 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.

Service approach
Device repair normally begins by using the device internal diagnostics and the following two-step
process:
1. 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
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.
