I don't get it. We have a boatload of these machines outside but we never had to change solenoids, boards, motors whatever because of this code.
Once we had a defective ATDC sensor and once a worn wiper for the ATDC sensor. That's it. We ALWAYS change the drum and developer completely as a pair without exception when they reach either the rated 80K for paying customers or for our rentals 120K with corresponding dipswitch settings of course.
Most important however is that ALL counters (PC Life, I/C Life and Developer) are reset to zero. Recheck again and again if they are really at "0". Often the developer counter comes back to "1" instead of "0" and resetting has to be done once again. After every reset you must switch off the machine with the fat main switch at the back and wait for about 20 seconds before turning on again. I reset the counter with the right hand door open so the machine will not start up.
Leave the side door open and go to f8 and Start and only NOW close the side door. This is what I am doing almost every week (Had two today by coincidence) it worked always until now.
Rule: Begin with proper resetting of the counters, replace drum and starter with new ones and ofcourse don't leave any old developer in the chamber cause when this mixes wit the new developer everything will be messed up.
