Maintaining Print Quality
6-2 Advanced Topics
If you are still dissatisfied with your print quality:
1. Print several test pages of your typical work output and compare the print quality to the
samples.
The print samples provided here are generic, that is, they show specific problems. Your
own print samples are typical of your printout problems and so you must compare prob-
lem effects and not the actual print pattern.
2. Generate test prints to compare with the quality samples. (See Appendix E for more
information.)
3. Identify a print quality sample included in this section that has the same flaws as your
print test.
4. Review and complete the actions listed under the print sample in the order in which they
are listed, generating a print after you complete each action.
5. Check the print’s quality; if the flaw or flaws are still present, continue to the next action
in the list. If the flaws are repaired, you do not have to complete the remaining actions.
If you complete all the recommended actions, including changing consumables, and the print
quality doesn’t improve, you may need to call your service representative to resolve the
problem. Refer to “Where To Call For Help” on page F-1 for the telephone number of your
nearest Hewlett-Packard service representative. Be prepared to give the service representative
the error code and any messages that appear on the Control Panel to assist in troubleshooting.
Print Quality Problems
When you have any print quality problems, check the following items before starting your
troubleshooting:
1. Check the Control Panel for any messages about consumables. If there is a “Consumable
at end life” message, replace the consumable and retest for print quality.
2. Check whether the paper being used meets Hewlett-Packard standards. (Refer to “Using
Paper” on page D-1.)
3. Check whether the paper is handled correctly (especially for creases or wrinkles).
4. Check whether the environment for the printer and the paper meets Hewlett-Packard
standards - especially for humidity. Refer to Table C-5, “Printer environmental
specifications”.
5. Check whether the rollers and the paper guides are clean (especially for scattered toner
or developer, accumulated paper powder and paper pieces).
6. Check the Economode setting; be sure it is OFF. (See “Economode” on page 2-17.)
7. Adjust the print density. (See “Density” on page 2-25.)
