Light print or fade

A vertical streak or an incorrect or faded color area appears on the page.

The paper might not meet HP’s paper specifications (for example, the paper is too moist or too rough). See “Print media specifications” on page 123.

One or more print cartridges are low. If you are using non-HP print cartridges, no messages appear on the printer control panel or in the embedded Web server.

The imaging drum might be low or empty. Print the Supplies Status page to check remaining life. Replace the imaging drum if it is low or empty.

If none of the print cartridges or the imaging drum is low or empty, remove the print cartridges one at a time and inspect the toner roller in each to see if the roller is damaged. If so, replace the print cartridge.

If the problem is not resolved, see “If the problem is not resolved” on page 86.

Dropouts
