Drum life is measured by minutes of rotation, not by copy count.

You're right and I know that fact, but the difference here is 30% of usual drum K life. It's too much even if they've done 50k pages in 50k jobs. In my experience drum life reaches 0% at 70k (give or take a few hundreds). If life stop is enabled drum stops around 82k.

Maybe I'm wrong and all of my customers have same kind of jobs .

Delivered an off lease machine with around 50k clicks on meter. K drum was at 0% but was working fine Print quality was great. 2 months later they called and said print was light. Replaced drum and prints were still light. Pulled K dev unit and noticed mag roller had hardly any dev on it. Went ahead and replaced developer unit and all was good. Ran about 20 pages and all look great! Less than 1 hour later they called and said machine has error code C-2558 which manual says is high K toner level. I read some posts on this forum and internet that this is a known issue. I was going to take some parts off a shop machine and return tomorrow. Was thinking about bringing the toner hopper, new toner and anything else suggested?

Any other ideas appreciated. Thanks

Is the dev unit turning? The predecessor to that machine (220/280/360) had a clutch that engaged to drive the unit. It would slip and cause feint prints and subsequent error codes. Check it out for nothing can't you.

Wanted to follow up with what I found. When I returned to machine first thing I did was look at black toner btl, wouldn't you know friggin aftermarket! K level was around 9, removed crap toner btl and left out, ran about 30 halftones on 11x17 paper. Got the level down into the 6 range like the other colors. Put new OEM toner in, did stabilization & graduation. Ran 100 pages level stayed in the 6.5 range. Been 1.5 days and no calls so looking like another strike against aftermarket toner. Personally I don't use aftermarket toners, this toner was in machine when I bought it from wholesaler.

All the counters matched so they are legit. Think the hours might of been why drum was at 0%.

Lesson learned, from now on I'm checking the toners when I get the machines in and replace any aftermarket.

There could be some error with original drum chip so wholesaler put in some old chip to start the machine and forgot it.
