I have a problem with a phantom paper jam in a HP Laserjet CP3525 printer, the error is 13.20.00 jam in right hand draw. I have checked all paper feed areas, replaced the user and transfer belt and blasted every censor that I am aware of with compressed air to no effect. If I bring up the censor diagnostic screen the following information is displayed.
A B C D E F G H I J K L M N O
1 1 1 0 0 0 0 0 1 0 0 1 0 0 0
I suspect that the problem relates to either a faulty or dusty sensor that I have not located yet, can anybody help?
