Problem Cause Print is light or faded, HP specifications | HP 2840

Problem	Cause
Print is light or faded.	The media might not meet
	HP specifications.

One or more print cartridges might be low. If you are using non-HP print cartridges, no messages appear on the device control panel or in the HP Toolbox.

Solution

Use media that meets

HP specifications. See Media specifications.

Replace any low print cartridges. See Changing a print cartridge.

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.

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

	If the light printing is on the left
	side of the page, the carousel
	might be dislocated.
Toner specks appear.	The media might not meet
	HP specifications.
	The paper path might need
	cleaning.

Contact your local HP Call Center or HP Authorized Dealer for service.

Use media that meets

HP specifications. See Media specifications.

Clean the paper path. See Clean the paper path, or see the HP Toolbox online Help.
