I'm running low on options for this one, and am wondering if anyone else has encountered fuser heating control problems with a 52 series color box so far?
Background: This machine is a few years old already, was one of our earlier installs of a 52 series box. so far it's been set and forget, and working really great all along. 135k total prints, 10k color and it's environment is in a farm equip dealership showroom with hard floors and surprisingly low dust considering the gravel parking lot and farmers walking past all day.
Then a couple of weeks ago it started getting C6220, C6320 high temp errors and J0107 all in the logs. Most (maybe all) of the errors occured during jobs that print reports consisting of many double-sided letter pages. I updated tht firmware, and I replaced the fuser unit, and noticed that the connector for the fuser was dislodged in the device, so I placed it back correctly and seated the hooks so that it wouldn't come away again. The connector looks to be in perfect condition. I'll be inspecting behind this connector during the NEXT visit...
I looked at the power outlet voltage and saw an idle voltage of 124vac, and loaded voltage of 118vac. I replaced the IH control PWB and immediately saw that the outlet voltage wasn't being dragged down so low anymore, staying above 120vac. A few days went by, and the errors/jams returned. I inspected the fuser connections, the HV to the IH coil separation part, the heavy cables and grounding of the IH coil, and tightened all screws for grounding and strapping.
I decided since this is a distant machine, I'd replace the engine board after inspecting all those grounding connections. This brings us to the present; the day after the engine swap, an overnight report generated a J0107 as per "usual". I haven't seen any C codes since I replaced the IH control PWB.
I've got about 13 hairs left to pull... and they're all basically grey at this point.
