found, it then tries to locate a JetAdvantage Management Connector (JAMc) instance on the network. If a JAMc is
found, the HP Smart Device Agent Base is securely upgraded to a full Smart Device Agent from JAMc, which will
then allow printed pages to be accounted for in a Managed Print Services (MPS) account. The driver-only web
packs downloaded from www.hp.com for the printer and installed through the Add Printer wizard do not install
this service.

1HP Maintenance/Long Life Consumables (LLC) life specications are estimations based on the LLC life test conditions listed below. Actual
individual life/yield during normal use varies depending on usage, environment, paper and other factors. Estimated life is not an implied
guarantee or warrantable.
*The LLC life test conditions:
●Print coverage: 5% evenly distributed across the page
●Environment: 17° to 25°C (62.6° to 77°F); 30%-70% relative humidity (RH)
●Media size: Letter/A4
●Media weight: 75 g/m2 (20 lb) plain media
●Job size: 4 pages or more on average
●Long-edge feed (Letter/A4)
Factors that can reduce life from the conditions above:
●Media narrower than Letter/A4 widths (thermal slowdowns equal more rotations)
●Paper heavier than 75 g/m2 (20 lb) (heavier media creates higher stress on printer components)
●Print jobs smaller than 4 pages (smaller jobs mean more thermal cycling and more rotations)

●Enable or disable the Cartridge Policy feature
●Enable or disable the Cartridge Protection feature
Introduction
Use HP Cartridge Policy and Cartridge Protection to control which cartridges are installed in the printer and
protect the cartridges that are installed from theft. These features are available with HP FutureSmart versions 3
and later.
●Cartridge Policy: This feature protects the printer from counterfeit toner cartridges by allowing only genuine
HP cartridges to be used with the printer. Using genuine HP cartridges ensures the best possible print
quality. When someone installs a cartridge that is not a genuine HP cartridge, the printer control panel
displays a message that the cartridge is unauthorized and it provides information explaining how to
proceed.
●Cartridge Protection: This feature permanently associates toner cartridges with a specic printer, or eet of
printers, so they cannot be used in other printers. Protecting cartridges protects your investment. When
this feature is enabled, if someone attempts to transfer a protected cartridge from the original printer into
an unauthorized printer, that printer will not print with the protected cartridge. The printer control panel
displays a message that the cartridge is protected, and it provides information explaining how to proceed.
CAUTION: After enabling cartridge protection for the printer, all subsequent toner cartridges installed in
the printer are automatically and permanently protected. To avoid protecting a new cartridge, disable the
feature before installing the new cartridge.
Turning the feature o does not turn o protection for cartridges that are currently installed.
Both features are o by default. Follow these procedures to enable or disable them.

Printer does not pick up paper or misfeeds
Introduction
The following solutions can help solve problems if the printer is not picking up paper from the tray or is picking
up multiple sheets of paper at one time. Either of these situations can result in paper jams.
●The printer does not pick up paper
●The printer picks up multiple sheets of paper
The printer does not pick up paper
If the printer does not pick up paper from the tray, try these solutions.
1. Open the printer and remove any jammed sheets of paper. Verify that no torn remnants of paper remain
inside the printer.
2. Load the tray with the correct size of paper for the job.
3. Make sure the paper size and type are set correctly on the printer control panel.
118 Chapter 6 Solve problems ENWW
4. Make sure the paper guides in the tray are adjusted correctly for the size of paper. Adjust the guides to the
appropriate indentation in the tray. The arrow on the tray guide should line up exactly with the marking on
the tray.
NOTE: Do not adjust the paper guides tightly against the paper stack. Adjust them to the indentations or
markings in the tray.
The following images show examples of the paper-size indentations in the trays for various printers. Most
HP printers have markings similar to these.
Figure 6-1 Size markings for Tray 1 or the multipurpose tray
Figure 6-2 Size markings for cassette trays
ENWW Printer does not pick up paper or misfeeds 119
5. Verify that the humidity in the room is within specications for this printer and that paper is being stored in
unopened packages. Most reams of paper are sold in moisture-proof wrapping to keep paper dry.
In high-humidity environments, paper at the top of the stack in the tray can absorb moisture, and it might
have a wavy or uneven appearance. If this happens, remove the top 5 to 10 sheets of paper from the stack.
In low-humidity environments, excess static electricity can cause sheets of paper to stick together. If this
happens, remove the paper from the tray, and ex the stack by holding it at each end and bringing the ends
up to form a U shape. Then, rotate the ends down to reverse the U shape. Next, hold each side of the stack
of paper, and repeat this process. This process releases individual sheets without introducing static
electricity. Straighten the paper stack against a table before returning it to the tray.
Figure 6-3 Technique for exing the paper stack
12
6. Check the printer control panel to see if it is displaying a prompt to feed the paper manually. Load paper,
and continue.
7. The rollers above the tray might be contaminated. Clean the rollers with a lint-free cloth dampened with
warm water. Use distilled water, if it is available.
CAUTION: Do not spray water directly on to the printer. Instead, spray water on the cloth or dab the cloth
in water and wring it out before cleaning the rollers.
The following image shows examples of the roller location for various printers.
Figure 6-4 Roller locations for Tray 1 or the multipurpose tray
The printer picks up multiple sheets of paper
If the printer picks up multiple sheets of paper from the tray, try these solutions.
1. Remove the stack of paper from the tray and ex it, rotate it 180 degrees, and ip it over. Do not fan the
paper. Return the stack of paper to the tray.
120 Chapter 6 Solve problems ENWW
NOTE: Fanning the paper introduces static electricity. Instead of fanning the paper, ex the stack by
holding it at each end and bringing the ends up to form a U shape. Then, rotate the ends down to reverse
the U shape. Next, hold each side of the stack of paper, and repeat this process. This process releases
individual sheets without introducing static electricity. Straighten the paper stack against a table before
returning it to the tray.

In low-humidity environments, excess static electricity can cause sheets of paper to stick together. If this
happens, remove the paper from the tray, and ex the stack as described above.
4. Use paper that is not wrinkled, folded, or damaged. If necessary, use paper from a dierent package.
ENWW Printer does not pick up paper or misfeeds 121
5. Make sure the tray is not overlled by checking the stack-height markings inside the tray. If it is overlled,
remove the entire stack of paper from the tray, straighten the stack, and then return some of the paper to
the tray.
The following images show examples of the stack-height markings in the trays for various printers. Most
HP printers have markings similar to these. Also make sure that all sheets of paper are below the tabs near
the stack-height marks. These tabs help hold the paper in the correct position as it enters the printer.

Follow these steps to check the estimated life remaining in the toner cartridges and if applicable, the status of
other replaceable maintenance parts.
Step one: Print the supplies status page
1. From the Home screen on the printer control panel, select the Reports menu.
2. Select the Conguration/Status Pages menu.
3. Select Supplies Status Page, and then, select Print to print the page.
162 Chapter 6 Solve problems ENWW
Step two: Check supplies status
1. Look at the supplies status report to check the percent of life remaining for the toner cartridges and, if
applicable, the status of other replaceable maintenance parts.
Print quality problems can occur when using a toner cartridge that is at its estimated end of life. The
supplies status page indicates when a supply level is very low. After an HP supply has reached the very low
threshold, HP’s premium protection warranty on that supply has ended.
The toner cartridge does not need to be replaced now unless the print quality is no longer acceptable.
Consider having a replacement available to install when print quality is no longer acceptable.
If you determine that you need to replace a toner cartridge or other replaceable maintenance parts, the
supplies status page lists the genuine HP part numbers.
2. Check to see if you are using a genuine HP cartridge.
A genuine HP toner cartridge has the word “HP” on it, or has the HP logo on it. For more information on
identifying HP cartridges go to www.hp.com/go/learnaboutsupplies.
Print a cleaning page
During the printing process paper, toner, and dust particles can accumulate inside the printer and can cause print-
quality issues such as toner specks or spatter, smears, streaks, lines, or repeating marks.
Follow these steps to clean the printer's paper path.
1. Load plain paper in Tray 1.
2. From the Home screen on the printer control panel, select the Support Tools menu.

CAUTION: Do not touch the imaging drum. Fingerprints on the imaging drum can cause print-quality
problems.
ENWW Resolve print-quality problems 163
4. If you see any scratches, ngerprints, or other damage on the imaging drum, replace the toner cartridge.
5. Reinstall the toner cartridge, and print a few pages to see if the problem has resolved.
Check paper and the printing environment
Step one: Use paper that meets HP specications
Some print-quality problems arise from using paper that does not meet HP specications.
●Always use a paper type and weight that this printer supports.
●Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids,
staples, and curled or bent edges.
●Use paper that has not been previously printed on.
●Use paper that does not contain metallic material, such as glitter.
●Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet
printers.
●Use paper that is not too rough. Using smoother paper generally results in better print quality.
Step two: Check the environment
The environment can directly aect print quality and is a common cause for print-quality or paper-feeding
issues. Try the following solutions:
●Move the printer away from drafty locations, such as open windows or doors, or air-conditioning vents.
●Make sure the printer is not exposed to temperatures or humidity outside of printer specications.
●Do not place the printer in a conned space, such as a cabinet.
●Place the printer on a sturdy, level surface.
●Remove anything that is blocking the vents on the printer. The printer requires good air ow on all sides,
including the top.
●Protect the printer from airborne debris, dust, steam, grease, or other elements that can leave residue
inside the printer.
Step three: Set the individual tray alignment
