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 paper might not meet HP specifications. Use paper that meets HP specifications.
The print cartridge might be defective or
low. If you use a non-HP print cartridge, no
messages appear on the product control
panel. Replace the print cartridge.
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 printer driver.
Toner specks appear. The paper might not meet HP specifications. Use paper that meets HP specifications.
The paper path might need cleaning. Clean the paper path.
Dropouts appear. A single sheet of paper might be defective. Try reprinting the job.
The moisture content of the paper is uneven
or the paper has moist spots on its surface. Try different paper, such as high-quality
paper that is intended for laser printers.
The paper lot is flawed. The manufacturing
processes can cause some areas to reject
toner.
The print cartridge might be defective or
low. Replace the print cartridge.
