Got a strange one. Customer called me out to look at their printer, leaving grey backgrounds and sometimes will not print. Replace the toner cartridge, grey backgrounds are gone, but when I cycle the power on the printer, all that comes up on the display is two rows of "*****"

So I unplug the printer from the ups and plug it directly into the wall socket and cycle the power again. This time it powers up just fine. That was about 2 weeks ago.

Today, customer calls me up and says its doing it again. She came into the office, the printer was in power save mode. Went to print something, printer wouldn't respond. She then Cycled the power, and she gets the "*****" again. After cycling the power a few times it can finally print again.

I'm starting to suspect the fuser at this point since I believe that the printer shows the "*****" while it waits for the fuser to warm up. I asked her to try a different printer cable in the mean time to see if that sorts out her issue with it not returning from power save mode, but the more I think about it, The more I think fuser. It would make sense to me that the fuser has to warm up before it will exit power save.

has anyone ever seen this before, do you agree that the fuser is most likley the cause?
