[Error Code] DesignJet 1050C+ error code 00345E:000008

[Mr_FixOK]

Hello all,

I have a customer that has had this plotter failing black printheads for several months. Each replacement interval is shorter than the last. When the last PH failed in one day we started the TS process from the service manual. We first ran the electronics test and R&R the carriage, then the trailing cable then the formatter trying new K PH's along the way still failing the test in diagnostics at each step. At this point we have replaced all parts suggested in the service manual and four K PH's to no avail. Everybody involved is frustrated, any suggestions? Oh Yeah the firmware revision is A52:02.

Thanks, Paul

I have not seen No. 80 Printhead for this printer. However, the No. 88 printhead has an expiry date. I suspect the No. 80 printheads are the same and could be expiring in the same year but different month or something. That could be why they seem to have shorter life. Unless they are actually not giving quality prints. One way to trick the printer in not recognising the expiry date is changing the date on the printer to say 2 years or more years back. I have no need to do this for printheads but did this (reverse the year) for cartridges and worked. Suspect this should work for printheads.
