this model really doesn’t like long periods of inactivity. I have been recommissioning stored machines that were in daily use up till 6 months ago and so far all have had stagnant developer. IE incorrect TCR value readings of 2-3%. This is dangerous as if its allowed to continue for any period of time the machine will end up adding toner when it’s not required.
removal and shaking of the IU’s (with finger blocking the inlet shutter) fixes the problem instantly and all 4 iu’s reported 9%+
I then run 25x cmyk gradation pages till the machine proves itself to me and I check the values again at around 6. something % and approve for release into the wild.
the other known issue with them is early version base boards discharge the battery after 6 months being disconnected from a power source. If the clock reports 2017 when first powered up after storage you’re up for battery replacement (soldered down) or at the very least setting up NTP settings in the machine for regular clock syncing. Late versions of thr base board in current production dont discharge the battery so quickly.
current firmware will also spin the developer sections at the maximum possible speed when stabilization is executed in expert mode or service mode, but only when all trays are pulled out and bypass is empty (secret mode) this may prevent having to shake the IU’s if done upto 3 times.
This is gonna be interesting for those who have experienced extended lockdowns etc or paused orders due to covid (why im doing this)
