General print-quality issues
The following examples depict letter-size paper that has passed through the product short-edge-first.
These examples illustrate problems that would affect all of the pages that you print. The topics that follow
list the typical cause and solution for each of these examples.
Problem Cause Solution
Print is light or faded. The media might not meet HP specifications. Use media that meets HP specifications.

If you use a non-HP print cartridge, no
messages appear on the product control
panel. Replace the print cartridge. See Print

If the print cartridge is not low or empty,
inspect the toner roller to see if the roller is
damaged. If it is, replace the print cartridge.
If the whole page is light, the print density
adjustment is too light or EconoMode might
be turned on. Adjust the print density, and disable
EconoMode in the product Properties.
