Im having trouble with this machine jamming for no apparent reason. It always jams one of two ways. The first way is described by the machine as a jam in the vertical transport section. With this jam there is always a sheet of paper leaving the fuser and a sheet having just hit the registration switch. the second way is described as a jam from what ever paper drawer was being used (didnt matter what drawer you choose it jams the same way). With this jam there was a sheet of paper leaving the registration switch and a sheet barely leaving the paper drawer. Ive replaced all feed rollers and the registration switch. When I go into service mode and check sensors there seems to be a slight delay between hitting the switch and it registering on the display. This delay varies some from test to test sometimes registering quickly and others kinda slow. Im now assuming there is a main board problem but was wondering what you guys thought or had seen in the past.
