We get a call from the customer stating that they need a new black IU, so we send out the tech with both the re-set tool and a new IU. The message being given wasn't for replacement it was saying "please insert correct imaging unit". Now keep in mind that the IU in question was 35k into its life and it threw this message up out of the blue. We did do a reset to verify that the correct info was in the IU and then replaced it with a new one when that didn't work, we also at this point have done a memory clear........ Nothing but the same message, has anyone seen this before and if so whats the fix? I know at this point what I'm probably going to hear
but its worth a shot. Thanks in advance for your help and input!
