HP7680 Blk/Yellow printer head problem

Can't make the sign go away. Pulled the head and cleaned it manually with a soft cloth & used a swab to clean the contact area down inside the printer.

All this came about when the printer bar got stuck. I have been able to solve the printer bar problem before by manually moving it over to the right side. However, this printer head problem is something new.

Want to know how to manually clean printer head

You can, but the objective is to soften the dried ink, that blocks the tiny ports.
In my estimate the alcohol will dry too fast.

Printer UNPLUGGED from power, and you may wish to don some gloves.
(Dishwashing gloves?)
The ink likes to go everywhere.

Remove the ink cartridge/s.

As you can see, the copper metal strip area, on the ink cartridge; has TINY little holes in it.
I use a clean soft static free cloth, and soak the end I'm going to use; in as hot a water as I can stand.

Then reduce the water in the cloth, (Squeeze), so the wet area, is just damp.
Wipe across the copper area, and it's tiny ports.
Wipe across once, then find a clean area on the cloth; and do so again.

Keep wiping until cloth comes away clean.
I also do the same on the metal area, of the printer; that the metal area of the ink cartridge touches.

There are matching tiny port holes there also.
Keep wiping, adjusting for a clean area after each wipe, until cloth comes away clean.

I then follow with a can of compressed air for computers, and make sure the areas are DRY.

Q-tips, and Isopropyl alcohol, (Rubbing alcohol), sounds more intelligent, to me.
However the amount used may fill up a small bag, IMHO.

I know what you're thinking. Is this guy N-uts?
Water and Electricity do not mix!

(Actually they do. Water is an excellent conductor)

I watch to make sure there are no drips from the cloth, when using it. Have a dry cloth handy for the other hand, if they do.

I also make SURE the areas are DRY, before reinstalling ink cartridges.

I find VERY warm water helps break down the dried ink.

Always willing to learn something new, however.

My printer does not work at all. when i turn it on there is an E in the copies area and the check print cartridge light is blinking but im pretty sure there is enough ink.

Try cleaning the printer head contact by using video head cleaner spray. Spray on both contact on the print cartridge and the print head inside the printer. And wipe off the dirt with clean soft cloth.<br /> <br /> First you need to power up the printer and open the front cover.<br /> The printer head will move into center and then you can pull out the power cord. Note that never clean the contact when power is on. Otherwise it may be permanent damage.<!-- from fixya rte -->

Perform the steps given below to clean the cartridges manually

=== Manually clean the ink cartridge and the contacts on the printer ===

1. Turn on the power to the unit and raise the cartridge access cover.
The cartridges will move towards the center.

2. After the carriage (the cartridge holder) stops, unplug the power
cord from the back of the unit. This will keep the cartridges from
moving back to the capping station.

3. Remove the cartridge(s) from the carriage.

4. Using a soft, clean, lint-free cloth or a cotton swab lightly
moistened with distilled, filtered, or bottled water gently clean
the face, edges and the electrical contacts. (Change to a clean
cotton swab as needed).

CAUTION: Be careful not to touch the ink nozzles on the bottom of
the print.

5. Inside the All-in-One, clean the contacts in the print carriage
with a slightly dampened soft, clean, lint-free cloth. Allow the
electrical contacts to dry completely.

now check if the issue still persists.

Should I use a dry toothbrush or a swab damp with alcohol to clean cartridges?

To clean the contact area or the print head on your ink cartridges, only use water, and a soft cloth or paper towel. A dry toothbrush can be used to gently brush the contacts in the printer, where the ink cartridges mount.
