In 15 years I have only been able to prove it was the papers fault 3 times, and 1 was today. After putting fusers in an HP 9050 and 5550 that sit side by side, I made some test prints off of the 9050. All was going well. Then I heard that awful sound. The sound of wrinkleing paper going through the machine. It looked as though it had tried to go through the machine sideways. I opened the tray and saw about 10 sheets trying to go through the rollers at once. An inspection of the ream showed that the blade that cut it, was so dull it meshed or bound the paper together in bunches of 20 to 30 sheets. And to make it worse, it was being stored outside in a storage building, soaking up humidity. Prints that made it through, had terrible curl.
No big finish to this, I just thought it would only interest other people in the business.
