The usual cause of "fake" paper jams is a prior "real" paper jam. One of two things occurs.

1. A small bit of paper tears off the jammed stock and hides from view, but keeps the printer jammed. These can be hard to find and remove, depending upon where they are.
2. In the process of yanking the jammed paper out of the unit, the sensor(s) become damaged or misaligned and give false jam indications. This usually needs repair or replacement.

ROS failure is the Laser Unit has gone bad and needs replaced.

There is no electric contact inside of toner catridge's bay (at the right) with metal catridge's shaft. Spring contact plate can break away or fold.

A fatal error 917 means there is a problem regarding the belt **** sensor.

Usually it means the printer can't see the transfer belt rotating.

First thing to try is to remove and re install the transfer belt, if that does not work you should replace the transfer belt.

Error 020 is a ROM dimm error, could be as simple as reseating/replacing Rom Dimm or a expensive main PCB, you need to get hold of a oki dealer, contact oki to find closest OKI repair agent.
