My TEXJET (hybrid) Epson 4800 printer was working flawlessly after a recent print head installation. The other night I turned on the printer to print a shirt and it goes through the startup process and then comes back to the home position just before "Ready" and I get the dreaded 0001001D CR servo parameter error. First thing I do is check the encoder strip to see if it had somehow got out of the sensor, but that was fine and I wiped it down. Then I checked to see if there was anything obstructing the movement of the head or if the belt had come loose. Everything looked good. So, I eased the carriage back into the Home position and I noticed it wouldn't dock (click into place). So, I positioned the head in the middle, plugged it back in and pressed the start button. The head moved smoothly but not quickly, back into position and began the Start process. It moved out and then back started to come out again and I get the error again. So, I shut it down and I noticed, again that the carriage wasn't locking into place. It moves back, but no clicking or locking. Nothing is obstructing the carriage, that I can see. Has anyone had a problem like this? Any ideas? Thanks for any and all help!
