[SOLVED] HP K8600 weird error
When assembling an old HP K8600 Officejet printer, I came up with this weird error. The carriage stalls and doesn't even come to the service station to complete the initialization cycle. This is what I have done so far: - checked for paper jams - the cartridges and printheads are properly installed (no lights are blinking) - checked the flat cable for proper contact - all wires are in place - cleaned the service station and replaced the motor - cleaned the encoder disk and strip - cleaned the alignment sensor - replaced the carriage board Should I try replacing the main board? Or maybe the flat cable? What else should I look for? A HP technician said the printer has reached the end of its service life. Well, it's like saying that a 10 year old car has reached the end of its service life after a flat tire. Funny isn't it? [SOLUTION] Another technician has serviced the printer before me. He mistakenly swapped two wires. There are two motors on the left side of the printer, behind the cartridge assembly. The upper one is the carriage motor, and the lower one is the paper motor. The yellow/green wire must go to the upper motor, and the blue/gray wire must go to the lower motor. Now the printer is working. Conclusion: the alleged "technician" has reached the end of his service life.
