1710n Flashing to Replace Drum
I work at a charter school in New Orleans. We have some older equipment including Dell 1710n's. I have one in particular that has the Replace Drum and Error lights flashing, but when I replace it with one out of a working 1710n, and reset the Drum counter (by opening the toner cover, turning the power off, holding the Cancel button, turning on the power, and releasing the Cancel button after all the lights flash), I get an Operator Panel Light error with the Continue button, Ready/Data, Toner Low/Replace Drum, and Load/Remove Paper lights turned on. This seems to be an error type not described in the User's Guide. Turning off and turning the printer back on makes the Operator Panel Lights go back to the original, Replace Drum and Error lights flashing. This makes me think some sensor for the drum is broken. Can you help me diagnose the problem? And fix it? Thanks.
I found a Lexmark service manual online (supposedly you can also get one from Lexmark, but not sure if it's free). I looked at the Parts Catalog's assembly diagram and the only thing I could think of that was even remotely related to the drum counter was the toner sensor. I replaced this from a Dell (Lexmark) 1700n and put it in the 1710n in question. This still resulted in the flashing Replace Drum and Error light combo on the Operator Panel. I tried resetting the drum counter, which predictably resulted in the Operator Panel Light error with the Continue button, Ready/Data, Toner Low/Replace Drum, and Load/Remove Paper lights turned on. I tried to search through the Service Manual for this error, without much success, and returned to the printer.
Upon turning it off and turning it back on, the printer seems to be ok, surprisingly. So either replacing the toner sensor did something, or waiting after resetting the drum counter did. I happen to think it's the latter, because the toner sensor likely has nothing to do with the drum counter. There does not seem to be any electrical connection between the imaging drum and the printer's logic board, so likely the printer is just counting the number of prints. When you reset the drum counter, it probably just rests the counter to zero, as opposed to communicating with the drum. But maybe it needs time to reset the memory (waiting after changing router settings in DD-WRT was always advised in their forums). So maybe patience after resetting the drum counter may lead to success, if the drum does not actually need to be replaced.
Since posting the first post in this thread, I've had other 17xxn's with the same issue, so I will try on those and report back.

the Dell 1710 is reportedly a Lexmark E240
