I was at a clients today that had two T650 cartridges for label applications, completely seize up mid cycle. So they did not get so hot that the wiper blade melted to the drum and it was not like a flipped wiper blade where you can rotate the drum backwards and fix it, these cartridges would have took a pipe wrench to get the drum to budge. Anyway, Lexmark must be aware of the issue since they sent two new replacement printers and new cartridges. The printers seemed to be ok but Lexmark wanted them back for some reason and I don't believe they were under warranty, I don't know for sure we were just there for their Xerox copier. So if you have a customer that has a cartridge that experiences this type of symptom have them contact Lexmark they may not just have to settle for a cartridge replacement.
