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 The Economode feature allows the device to use less toner per page. Selecting
Economode extends the life of the toner supply and reduces the cost per page but reduces print
quality. The printed image is lighter but is adequate for printing drafts or proofs. Hewlett-Packard
does not recommend full-time use of Economode. If Economode is used full-time, the toner
supply might outlast the mechanical parts in the print cartridge. If print quality begins to degrade
under these circumstances, install a new print cartridge even if the print cartridge still contains
toner.

Manage the print cartridge
Print-cartridge storage
Do not remove the print cartridge from its package until you are ready to use it.
CAUTION To prevent damage to the print cartridge, do not expose it to light for more than a
few minutes.
Use genuine HP print cartridges
When you use a genuine new HP print cartridge, you can obtain the following supplies information:
Percentage of supplies remaining
●
Estimated number of pages remaining
●
Number of pages printed

HP policy on non-HP print cartridges
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either new or
remanufactured. Because they are not HP products, HP cannot influence their design or control their
quality.
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 27. 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
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:
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
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the exterior of the device.
Clean the ADF
If the ADF has trouble feeding documents, clean the ADF pickup roller assembly.
1. Turn off the device and unplug the power cord.
2. Open the ADF cover.
3. Press the round blue button while lifting the green lever. Rotate the green lever until it stops in the
open position. The pickup roller assembly should remain on the surface.
40 Chapter 3 Maintenance ENWW
Page 53
4. Remove the assembly, and then wipe the assembly with a soft, dry, lint-free cloth.
5. Replace the assembly, with the largest roller down, in the upright holder, and then press until the
assembly snaps into place.
6. Make sure that both sides of the assembly are secured by the blue hooks.
7. Lower the roller assembly, and then close the ADF cover.

8. Plug in the device, and then turn on the device.
Clean the scanner lid backing
Minor debris can accumulate on the white document lid backing that is located underneath the scanner
lid.
1. Open the scanner lid.
2. Clean the white document lid backing by using a soft cloth or sponge that has been moistened with
a mild soap and warm water.
3. Wash the backing gently to loosen debris; do not scrub the backing.
4. Dry the backing by using a chamois or soft cloth.
CAUTION Do not use paper-based wipes because they might scratch the backing.
5. If this does not clean the backing well enough, repeat the previous steps and use isopropyl alcohol
to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth to remove
any residual alcohol.

Clean the scanner glass
Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the
accuracy of special features such as fit-to-page and copy.
NOTE If streaks or other defects appear only on copies produced using the automatic document
feeder (ADF), clean the scanner strip (step 3). It is not necessary to clean the scanner glass.
1. Open the scanner lid.
2. Clean the glass by using a damp, lint-free cloth.
CAUTION Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon
tetrachloride on any part of the device; these can damage the device. Do not place liquids
directly on the glass. They might seep under it and damage the device.
3. Clean the scanner strip by using a damp, lint-free cloth.
ENWW Clean the device 43
Page 56
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).

Pickup/feed/delivery system
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.
The following components work together to feed media through the device:
M1, main motor
●
M2, fuser motor
●
SL1, tray 1 pickup solenoid
●
SL2, tray 2 pickup solenoid
●
PS502, duplexer media-detection sensor
●
Output-bin-full sensor
●
PS901, top-of-page sensor
●
PS902, tray 1 media-detection sensor
●
PS903, media-width sensor
●
SR1, top output-bin delivery flag
●
SR2, fuser-delivery flag
●

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 4-9 Laser/scanner system
ENWW Basic operation 63
Page 76
Image-formation system
Laser printing requires the interaction of several different technologies, including electronics, optics, and
electrophotographics, to provide a printed page.
Figure 4-10 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 the figure
system on page 64 and described in the following sections.
Figure 4-11 Image-formation
Figure 4-11 Image-formation system
64 Chapter 4 Theory of operation ENWW
Page 77
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 4-12 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 4-13
Developing on page 65. The charges are actually negative, but they are more positive than the
charges on the developing cylinder.
Figure 4-13 Developing
ENWW Basic operation 65
Page 78
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 4-14 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 4-15 Separation
66 Chapter 4 Theory of operation ENWW
Page 79
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.
Figure 4-16 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 top cover 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 failed to read or write three times in a row, it determines that the memory
tag is abnormal and notifies the formatter of a "cartridge memory abnormality warning".
