HOW DO I MANUALLY CLEAN THE PRINTHEADS ON MY HP 970CSE DESKJET PRINTER?

SOURCE: HP D135 - replaced printhead - still doesn't print in that color

try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.

Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

SOURCE: printing yellow for black

Hi Jan,

Can you confirm that you are using a CIS or non-HP cartridges with this printer?

It sounds a lot like the printhead has reached a clogging point where sediment has built up in the black portion and loosens enough to printer a few lines before it re-asserts itself again.

Based on my experience of this printer, if you're using a non-HP delivery system for ink then you should consider replacing the black ink with a dyebase alternative instead of pigment.. Replacing the Black/Yellow printhead and running a number of test prints to purge the pigment ink in the printhead should then result in a clean and more reliable printout in future.

One other vector for problems is the cleaning area and I've found that this can become soiled with excess ink causing cross contamination within the inks of one printhead. As yet I've not found a reliable solution to counter this sort of issue.

Hope this gives some clues and hopefully some ideas of a fix.

Martin

SOURCE: HP Business Inkjet 2200/ Printing Problems

I had this same problem. HP worked with me to solve this problem for over a week. I jumped through a hundred hoops....all to no avail.
The bottom line ended up being....Buy a knew printer because it would cost more to ship and repair the printer than it is worth. A fifty dollar turn-in fee was made for up-grading. I did this because there is no solution when the printer refuses to align itself so it can print
from the black cartridge.....sorry johnfleff

SOURCE: my hp deskjet 1280 will not print yellow

Hello, this is Harry from www.BusinessSpread.co.uk.
We had the exact same problem when printing, we used 3 different 78 colour ink cartages and they all said 100% full but did not work. We then had a look at the dates on the box and they were all expired so when buying ink from anywhere even PC world or Curry’s always look at the expiry date.
Today I went to PC world and purchased a new 78 ink which said expires July 2011 and it works perfectly fine.

Try this :

Take out the power cable from the back of the printer keep on tapping the power button for 30 secs ; then plug it back.
Take out the catridges clean them with a Lint free cloth (copper contacts); also clean the catridge slot of the printer; put in back the catridges ;
Unplug the power cable from the back of the printer; press and hol down the (#) and the (6) button simultaneously with one hand and with the other hand put in back the power cable; and then release the (#) and (6) button;
It will perform a reset on the printer
IF still then it doesn't work then the catridge slot's copper contacts has gone bad and need to replace
