The low voltage power supply is located in the bottom right side of the machine. Remove the right side cover and you will see it at the bottom of the machine. It is the full length of the unit. All you can do is check the fuse but its unlikely to be at fault unless there was a power surge at some time. If the PSU has blown then the cost of a new one and fitting will be more than half the value of the whole machine.

How to clear a fake paper jam in oki B6250 printer
The usual cause of "fake" paper jams is a prior "real" paper jam. One of two things occurs.
- 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.
- 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.
