I have a Konica 7035 that has code F-35-6 show up. We found a major paper jam, removed it after taking apart part of the copier but the code remains. Any advise? Also, where can I find a manual for this machine? Thanks for any help.

All it takes is one tiny shred to trip the jam sensor, check again.

Place thick paper and push it manually while rotating the rollers in that way the small paper jam remain inside will comeout.

When C-35**,C-38** or C-39**(fusing temperature related
abnormality) occurs, be sure to repair defective parts before
setting DIPSW3-1 to 0. Setting DIPSW3-1 to 0 with defective
parts not repaired results in a fire.

Replace the developer and the drum and clean the sensor that monitors the drum. and after developer is replaced ensure you run the required procedure in 36 mode.

A 46-11 code indicates a communication failure between the A/D converter board and the main control board. Likely a bad or poorly seated ribbon cable. Try to reset the machine by turning off the main power switch on the side of the machine for 10 seconds and re-powering up. If the problem persists you will need to call a technician.

There is a small sensor on the fuser that most likely has become disloged. It requires a lot of disassembly to get to.
But an E2 code is that sensor not being cleared off. It pops out of the frame sometimes during paper removal.
