Have you ever worked on a problem machine you couln`d fix, maybe a lemon.

The only thing that beat me was a Ricoh MP C1500 duplex tray. Changed the cct board, all the sensors and clutches and still the thing wouldn't work. I suspect there was a problem in the wiring loom but couldn't prove it. In a fit of rage I threw the thing in the bin and booked a new one out of the store under the pretext that it was cheaper solution then me wasting my time. A year later the copier joined it!
Had several copiers that started working again and I wasn't too sure what I did to fix it. You just give a silent prayer of thanks to the copier gods and move on to the next problem.

I had a savin 9920. When they first came out. 1 machine in a xray dept.. Fix one issue, 2days later something else. After about 2 months of this thing I asked my service manager for a can of yellow paint. LEMON!!!!!! about 150 other machines of that make ran like tops!

I like the ones that fix themselves, although sometimes I would like to know what I did. But, like you, most times I just move on to the next one.

had a canon np1215 once that the exposure lamp would cut out after 1/3 scanning of the original. me and my partner in crime, well you name it we changed/metered it (lamp cables, lamp carriage, lamp driver boards etc just to name a few) still could not cure the fault. eventually we binned it due to the 'beyond economical to repair' thing

Then I had this CANON, I cant recall the exact model, but something like np6221,or np6225? which was displaying a paper jam immediately its switched ON. The owner first took it to some other technicians who were unsuccessful on it before he was referred to me. I replaced all the known sensors in the machine to no avail, substituted both main PCB and dc controller, still NOTHING !
In the end we advised the owner to buy another machine. We still believe that was the " worst" copier brand manufactured and released by canon, at least in this part of the globe
