There have been some issues with the firmware causing some "unexplainable" happenings with the printer!! Unless you were aware the problem existed with the firmware, changing of the DC controller, power supply, fuser and even the formatter were all possible fixes to the problem the printer was exhibiting. Changing any of these components would not correct the issue. The printer would work fine form Tray 1 most all the time. A much different story from Tray 2 though. The printer will receive the data and show processing, the engine will cycle up like its going to pull paper and print the file... then just stop! Display will show IDLE with no error generated on the display or error log. Turns out there was a problem with the printer's firmware and fuser, causing this to happen at random. Upgrading the printer's firmware to 4.060.7 or higher, and replacing the fuser at the same time will correct this "bug " that has been in your printer.
