Want to get a single color print other than Black, Can i refill 12A toner with magnetic color powder?

SOURCE: Color toners are empty

Press Green Tick, Right, -> System Setup -> Right, Right, -> Print Quality, Right -> Replace Supplies. Change from stop at out, to override at out. It'll let you print, and you'll get loads more out of your toner before the pages start to fade.

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.

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.
