Congure the HP toner-cartridge-protection supply settings

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.

● 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 specic 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.

To resolve these or other print-quality problems, try the following solutions in the order presented.

For information about resolving specic image defects, see Resolving print quality problems.

Print from a dierent software program

Try printing from a dierent software program. If the page prints correctly, the problem is with the software
program from which you were printing.

If the page does not print correctly, try updating the printer and print again. See Update the printer.

Check the paper-type setting for the print job

Check the paper type setting when printing from a software program and the printed pages have smears,
fuzzy or dark print, curled paper, scattered dots of toner, loose toner, or small areas of missing toner.

78 Chapter 8 Solve problems ENWW

Check the paper type setting on the printer

Verify that the tray is loaded with the correct type of paper.

Check the paper type setting (Windows)

1. From the software program, select the Print option.

2. Select the printer, and then click the Properties or Preferences button.

3. Check the paper settings.

Check the paper type setting (OS X)

1. Click the File menu, and then click the Print option.

Check toner-cartridge status

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: Find supplies information

From the printer control panel, press (the Information button) to print an information report.

Step two: Check supplies status

1. Open EWS (see To access and use the Embedded Web Server (EWS)) to look at the supplies status report

of 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
conguration report indicates when a supply level is very low.

Once an HP toner cartridge has reached Very Low, HP’s Premium Protection Warranty on that toner
cartridge 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
conguration report lists the genuine HP part numbers.

2. Check to see if you are using a genuine HP cartridge.

A genuine HP toner cartridge has “HP” on it, or has the HP logo on it. For more information on identifying
HP cartridges go to www.hp.com/go/learnaboutsupplies

ENWW Improve print quality 79

Clean the cartridge

During the printing process, cartridges might be contaminated by paper dust and cause print quality issues
such as background issues, vertical dark bands, or repetitive horizontal banding.

Follow these steps to improve the above mentioned print quality issues:

1. Open EWS. See To access and use the Embedded Web Server (EWS).

2. Click the System tab, and then click Service.

3. In the Cartridge Cleaning Mode area, click Start to begin the cleaning process.

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.

Use the following procedure to print a cleaning page.

1. Open EWS. See To access and use the Embedded Web Server (EWS).

2. On the System tab, click Service.

3. In the Fuser Cleaning mode area, click Start to begin the cleaning process.

Visually inspect the toner cartridge

Follow these steps to inspect the toner cartridge.

1. Remove the toner cartridges from the printer, and verify that the sealing tape has been removed.

2. Check the memory chip for damage.

3. If you see any damage on the toner cartridge, replace the toner cartridge.

4. 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 specications

Some print-quality problems arise from using paper that does not meet HP specications.

● 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.

80 Chapter 8 Solve problems ENWW

Step two: Check the environment

The environment can directly aect 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 specications.

● Do not place the printer in a conned 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.

Adjust Print Density

Complete the following steps to adjust the print density.

1. Open EWS. See To access and use the Embedded Web Server (EWS).

2. Click the System tab, and then select System Setup from the left navigation pane.

3. Select the correct density settings.

4. Click Apply to save the changes.

Image defects, no matter the cause, can often be resolved using the same steps. Use the following steps as a
starting point for solving image defect issues.

1. Reprint the document. Print quality defects can be intermittent in nature or can go away completely

with continued printing.

2. Check the condition of the cartridge. If a cartridge is in a Very Low state (it has passed the rated life),

replace the cartridge.

3. Make sure that the driver and tray print mode settings match the media that is loaded in the tray. Try

using a dierent ream of media or a dierent tray. Try using a dierent print mode.

4. Make sure that the printer is within the supported operating temperature/humidity range.

5. Make sure that the paper type, size, and weight are supported by the printer. See the printer support

page at www.hp.com/support/ljM232MFP for a list of the supported paper sizes and types for the
printer.

NOTE: The term “fusing” refers to the part of the printing process where toner is aixed to paper.

Table 8-17 Output defects

Description Sample Possible solutions

Output curl:

Printed paper has curled edges. The curled
edge can be along the short or long side of
the paper. Two types of curl are possible:

● Positive curl: The paper curls toward

the printed side. The defect occurs in
dry environments or when printing
high coverage pages.

● Negative curl: The paper curls away

from the printed side. The defect
occurs in high-humidity
environments or when printing low
coverage pages.

Output stacking:

The paper does not stack well in the output
tray. The stack might be uneven, skewed,
or the pages might be pushed out of the
tray and onto the oor. Any of the
following conditions can cause this defect:

● Extreme paper curl

● The paper in the tray is wrinkled or

deformed

1. Reprint the document.

2. Positive curl: From the printer EWS,

select a heavier paper type. The
heavier paper type creates a higher
temperature for printing.

Negative curl: From the printer EWS,
select a lighter paper type. The
lighter paper type creates a lower
temperature for printing. Try storing
the paper in a dry environment prior
or use freshly opened paper.

3. Print in duplex mode.

4. If the problem persists, go to
