HP Printer Error Code E8 — What It Means & How to Fix It

What Does This Error Mean?

The E8 error means your HP printer has a print head problem. The print head is the part that sprays ink onto the paper. This error usually requires cleaning or reseating the print head to fix.

Affected Models

HP OfficeJet Pro 8600 Series
HP OfficeJet Pro 9000 Series
HP ENVY 6000 Series
HP DeskJet Plus 4100 Series
HP ENVY Inspire 7900 Series

Common Causes

The print head is clogged with dried ink from sitting unused for too long
The print head is not properly seated in its carriage
Electrical contacts between the print head and printer are dirty or corroded
The print head has reached the end of its lifespan and is failing
A power surge or interrupted print job corrupted the print head communication

How to Fix It

Turn off the printer and unplug it. Wait 60 seconds, then plug it back in and turn it on.

A power cycle resets the print head communication and clears temporary errors.
Open the cartridge access door. Locate the print head — it is the piece the cartridges snap into.

Not all HP models have a removable print head. Check your manual if you are unsure.
If the print head is removable, lift the latch and gently pull it out. Clean the electrical contacts on the bottom with a lint-free cloth dampened with distilled water.

Do not use tap water or alcohol — distilled water is safest for the delicate contacts.
Also clean the matching contacts inside the printer where the print head sits. Let everything dry for 5 minutes.

Make sure there is no lint or moisture left before reinstalling.
Reinstall the print head firmly and snap the latch closed. Reinstall the cartridges and close the access door.

If the error persists, run the 'Clean Print Head' tool from the HP Smart app or printer menu.

When to Call a Professional

If cleaning and reseating the print head does not fix the E8 error, the print head itself may need replacement. On some HP models the print head is built into the cartridge, making it easy to swap. On others, a technician may be needed. Expect to pay $100 to $200 for parts and labor.

Frequently Asked Questions

Can I replace the print head myself?

On many HP inkjet models, yes. The print head lifts out after releasing a latch. Replacement print heads can be ordered from HP's website or Amazon. If your model has the print head built into the cartridge, just replace the cartridge.

How do I prevent the E8 error from happening again?

Print at least one page per week to keep the ink flowing and prevent clogs. If you will not use the printer for a long time, run a print head cleaning cycle before storing it. Keep the printer in a cool, dry place.

Is the E8 error covered under HP warranty?

If your printer is still under warranty and the print head is defective, HP will typically repair or replace it at no cost. Check your warranty status at support.hp.com. Keep your proof of purchase handy.
