I have now tried to clean and calibrate the Print Heads, but with no success. In fact, to clean the Print Heads, the printer should print a page where I can see if it is fine. However, as soon as the PC sends this page to the printer, it would show briefly in the Print Queu and would dissapear after a second or two. In the meantime the printer does not react on this and still indicated that the Black and/or Yellow cartridge needs to be replaced.
Please help.
I have already loaded brand new ink cartridges.
The Repair Shop reported that they already fixed a firmware bug.
The Printer worked correctly once or twice after that.
Do I need to re-install the Printer Driver?
I only have the Printer Driver on the CD that came with the Printer - do I need a newer version of the Printer Driver?
Please advise.

Only the Printhead light is on; none of the colors
Took printheads out to clean & found a lot of ink in the area below them & some dried ink-crud on the plastic flap under the printheads. I bought this printer new from HP in 2004 & have never had to clean printheads til now.
Took printer apart to cleanup the mess. reassembled with cleaned printheads. No difference.
Am able to print & appears to work ok, but don't know for how long.
Used the reset procedure in the manual to reset printer, still have Printhead light on.
Am using original drivers I installed when purchased machine I think.
Mine is the HP Business Inkjet 1200d
Thanks in advance.
