Has anyone ever dealt with a T05-603 error?
Here's what happened to this machine:
- A burnt smell came out of the front of the machine upon trying to make a master. The drum didn’t seem to be moving at all, resulting in a T05-603 error.
- The machine was turned off immediately, unplugged and left untouched for a few hours until the smell vanished completely.
- Upon turning it on and pressing the Start button as per machine’s request, the printer started up normally. I thought it’d be wise to remove the drum before doing anything else. After pressing the drum release button I hear the initial movements of the drum prior to being released, but the final horizontal push of the drum didn't occur and the drum remains locked, giving me an T05-603 error again.
- I unlocked the drum manually and noticed that the smell was coming from the front of the drum. I’ve opened it up and saw that the drum PCB was fried.
- I put the machine back together, turned it on, insert a different drum, press the Start button again per printer’s request and the default 'Ready to Print' appears. But when I press the Test Print button I’m greeted by the same T05-603 error after a few seconds of apparent inactivity.
As per the technical manual:
T05-603: The vertical-centering sensor does not switch OFF → ON even when the vertical-positioning pulse motor is moved 12 mm in the ON direction.
It seems like the fried PCB on the drum has also damaged some of the printer’s electrical system but I don’t know where to start tracing this error. Any ideas will be greatly received. I’m being paid to fix this machine so if anyone can provide solid results I’ll gladly pass on proper payment.
Thank you
