Check the print cartridge
Check the print cartridge, and replace it if necessary, if you are having any of the following problems:
● The printing is too light or seems faded in areas.
● Printed pages have small unprinted areas.
● Printed pages have streaks or bands.
NOTE:
If you are using a draft or EconoMode print se tting, the printing might appear light. HP does
not recommend the 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 and is no longer
acceptable, consider replacing the print cartridge
If you determine that you need to replace the print ca rtridge, print the supplies status page to find the
part number for the correct genuine HP print cartridge.
Type of print cartridge Steps to resolve the problem
Refilled or remanufactured
print cartridge Hewlett-Packard Company cannot recommend the use of non-HP supplies, either new or
remanufactured. Because they are not HP products, HP cannot influence their design or control
their quality. If you are using a refilled or remanufactured print cartridge and are not satisfied
with the print quality, replace the cartridge with a genuine HP cartridge.
Genuine HP print cartridge 1.The product control panel or the supplies status page indicates Very Low status when the
cartridge has reached the end of its estimated useful life. Replace the print cartridge if
print quality is no longer acceptable.
2. Visually inspect the print cartridge for damage. See the instructions that follow. Replace
the print cartridge if necessary.
3. If printed pages have marks that repeat several times at the same distance apart, print a
cleaning page. If this does not solve the problem, use the repeating defects information in
this document to identify the cause of the problem.
Inspect the print cartridge for damage
1.Remove the print cartridge from the product, and verify that the sealing tape has been removed.
2. Check the memory chip for damage.

CAUTION:Do not touch the green roller (imaging drum) on the bottom of the cartridge.
Fingerprints on the imaging drum can cause print-quality problems.
4. If you see any scratches, fingerprints, or other damage on the imaging drum, replace the print
cartridge.
5. If the imaging drum does not appear to be damaged, rock the print cartridge gently several times
and reinstall it. Print a few pages to see if the problem has resolved.
