HP Office Jet 7110 All-in-One

Did you let one of your inks run dry? If so, you need to replace the effected printhead. This model has two, one for black and yellow, and a second for cyan and magenta. If you let the yellow run dry but have tons of black, it still effects the black/yellow printhead. Same with the other, either color going dry makes its printhead go bad. Either printhead will set you back about $75. Easy to remove and replace once you get the new printhead.

Bottom line with this model of printer...DON'T let you inks run dry. A new ink cartridge is $20 vs. $75 for a new printhead.

FYI - This is the most common mistake/problem with this printer. The Inkheads are built to last at least 40,000 prints. That's several years for most of us, that is unless you let the inks run dry.

This document provides information on how to replace a printhead or ink cartridge.A printhead may need replacing when print quality issues cannot be resolved by cleaning the printheads or a front-panel display message indicates a printhead needs to be replaced.An ink cartridge needs replacing when a front-panel display message indicates either:

• Low ink levels
• Ink cartridge approaching expiration date

CAUTION: Never remove an ink cartridge and a printhead at the same time.

Follow these instructions carefully. There may be more than one faulty print head.

To solve the printing problem..


# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.

1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

# Reinstall the cartridges, making sure you snap them correctly into the printer.

I'm not sure you specified the correct printer. The 7110 printhead is not pentagonal. Is your printer the 7110 all-in-one?

HP 7110 Printer

The problem with the printer is it does not work, there are flashing lights and the message it gives you is to turn the power on and turn it back on. Needless to say when I reboot the system and unplug the printer and plug it back up, I get the same message, does anyone have any solutions to this problem????
