My HP 2600 business inkjet tells me to replce the printhead.
It is a new one...
Tried several older ones and cleaned the contact.
Keeps giving the "replace" message
How can I stop this and continu printing ???:mad:
After a lot of trouble finaly installed my CIS for canon ix4000
All the led-lights are burning.
But the warning light is also flashing.
The computer say:problem with inktanks: remove cartridges with non-burning lights..
But they are all burning..
What to do ????
