How to clean ink cartridges HP deskjet printers

You need the following items to clean the print cartridges:

• Distilled water (tap water can contain contaminants that
can damage the print cartridge)
• Cotton swabs or other soft, lint-free material that will not stick
to the print cartridge

Be careful not to get ink on your hands or clothing as you clean.

To prepare to clean

1. Open the HP Deskjet cover.
2. Wait until the print cartridge cradle moves to the
center of the HP Deskjet and is idle and quiet.
3. Remove the print cartridges and place them on a piece
of paper, with the copper strips facing up.

CAUTION: Do not leave the print cartridges outside the HP Deskjet for more than 30 minutes.
To manually clean print cartridge contacts

1. Lightly moisten a cotton swab with distilled water and
squeeze any excess water from the swab.
2. Gently wipe the print cartridge copper contacts with the cotton swab.

CAUTION: Do not touch the print cartridge ink nozzles. Touching the ink nozzles will result in clogs, ink failure, and bad electrical connections.


1 Ink nozzles (do not touch) 2 Copper contacts
3. Repeat this process until no ink residue or dust appears on the swab.
4. Insert the print cartridges in the HP Deskjet, and then close the cover.

The printer's black ink cartridge won't print without the Tri-color print cartridge

Most of the HP printers are designed to allow printing onlywhen all cartridges are installed and
have ink.
Install a new tri-color ink cartridge and printing will continue as usual.
My printer, which is HP, does the same thing as yours, until I replace the empty cartridge,
printing stops.

My deskjet 3745 wii not print with new ink. The cartridge shows full and the printer goes thru all the motions. The final print is no color and light black

Use the HP software (installed when you installed the printer) to run a "print-head-cleaning" cycle -- you've got lots of ink, but the print-heads are CLOGGED.

Seems that your black ink cartridge is damaged, try it in another printer of the same type to see if it works, or replace it with a new one.
