BZ1200 error code 4705

[Downunder]

BZ1200 - 6 million on clock. Intermittant code 4705 -- paper jams at registration unit. Have replaced motor, clutches, main boards, adu board, registration unit. jam code also indicates that paper was fed from tray 3 even though it was fed from another.

Remove jam, turn off copier and then it will run for a while, sometimes even a day with no problems. Stock is good. Any suggestions would be appreciated. We are about to try nvrm next. Firmware up to date
