HP Designjet 1050C Printer head error - need help bad

Hi, I'm new to the board and have a tough question for me.  I bought a used 1050C and knew that the black printhead needed to be replaced per the front panel.  Bought a new printhead, replaced it, and started getting the "reseat" yellow printhead error.  I reseated the old one several times, cleaned the contacts with HPs cleaning tool and a wet coffee filter, no luck.  Replaced the yellow print head, no luck, replaced all the print heads, no luck.  I am at the end of the rope.


Ran the electronics test procedure and came up with the failure for the yellow printhead - 00345E 000004.  I replaced the trailing cable since it looked worn.  No help.  Any suggestions?  After all new catridges, actually 2 new yellow ones, I am out of money, time and frustrated.


Please help me, I need all the help I can get!

Sometimes one bad printhead can cause another printhead to give a reseat message. That said before you replaced the black printhead did the yellow printhead show as being good. If it did it is possible the new black printhead is bad and is causing the yellow reseat message. If the printhead is within warranty return to hp for replacement.

It looks like an issue with printhead itself, so you may try replacing the yellow printhead with a working one.


Do check the warranty start or end dates before buying & installing printheads & ink cartridges.


You may claim the defective printheads for replacement rather than buying new one for testing purpose.


If at all a working printhead does not resolve this issue, then I would suggest to obtain help from HP support, as it would require close physical inspection of device hardware (ink tubes, carriage, service station etc..)
