Question about HP DesignJet 750c InkJet Printer
Having problems trouble shooting a clear carriage path turn swith off/on on a HP 750C 24" plotter I've tried lube on the rails, they did need it but did not work I've tried replacing the trailing cable, as the sensor read the encoder strip. Nothing that did not work. I've tried replacing the Y motor as I've read the CPA has driver rt and driver lt for "friction" etc. Anyway replacing the motor did not work. I have not replaced the encode strip, it looks perfect, no scratches, no marks, no wrenckles, nothing During inital power up the carrage travels to the left bumps and travels to the right, when it travels to the right it just runs into the paper cutter and displays the message "clear carriage path and switch off/on" It does it each time you power up
Sounds like it can not find home. Is there a limit switch? If not there may be a failure in the counter from the stepper motor.
