Our M453N machine produces two 1-2" parallel wrinkles starting on the bottom of pages when copying or printing. We had a technician who inspected the machine and after 30 seconds he said we'd be better off buying a new machine, which of course he was more than happy to offer (!). Tossing a machine this size isn't a decision made lightly, so is there something worth checking/cleaning on the machine before retiring it? Thanks,
