PRINT QUALITY

[huntingmark]

My HP 7850 is cutting off lines, like only printing the top 1/2 of a text line. HELP.  There must be a menu somewhere that will allow me to run a head cleaner or alignment program, but I do not see it.  I read that there is a menu option on the control panel, where is this panel?   Should I remove the cartridges (instant ink)?  Thanks in advance.

Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

Clean the ink cartridges

• On the control panel, swipe down to open the Dashboard, and then touch the Setupicon.
• Swipe up on the display, and then touch Printer Maintenance.
• Touch Clean Cartridges, and then touch Continue.
• A Print Quality Diagnostic page prints.
• Examine the Print Quality Diagnostic page.
• If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. Repeat these steps for the third cleaning stage, if necessary.
• If the print quality is acceptable, touch Done. You can stop troubleshooting.

Manually clean the area around the ink nozzles

Gather the following materials:

A clean, lint-free cloth or a clean, dry cotton swab

Distilled or bottled water

CAUTION: Do not use tap water because it might contain contaminants that can damage the printhead.

Open the ink cartridge access door.

Wait until the printer is idle and silent before you continue.

Lightly press down on the ink cartridge to release it, and then pull the ink cartridge out of its slot.

CAUTION: Do not remove both ink cartridges at the same time. Remove and then clean each ink cartridge one at a time. Do not leave an ink cartridge outside the printer for more than 30 minutes.

Hold the ink cartridge by its sides.

Lightly dampen a clean, lint-free cloth or swab with bottled or distilled water.

Clean the face and edges around the ink nozzle with the cloth or swab.

CAUTION: Do not clean the ink nozzle plate.

Nozzle plate - Do not clean

Area surrounding ink nozzle - Do clean

Ink cartridge contacts - Do not clean

Wait 10 minutes for the cleaned area to dry before you continue.

Hold the ink cartridge by its sides with the contacts toward the printer, insert the ink cartridge into its slot, and then gently push the ink cartridge until it snaps into place.

Repeat these steps to clean around the nozzles on the other ink cartridge.

Close the ink cartridge access door.
