Hello,

had the same problem. It is easily fixed.
On my printer a OKI C5750 is had to main covers, at the front (which you have to open to fix a paper jam) and a big cover on top (which you need to open to replace toners).
On the left is a piece of plastic which (when closed) presses on a switch.
When you open both covers, and close the top one, you can see it on the left when it comes down.

You can easily remove the error (only for a brief moment) by prushing the shining metal switch to the back.

But the problem is that one of the rollers is in a wrong position.
So just take a flat screwdriver and press on the bottom roller, and it will click and the problem will be gone when you close the covers.

the drive control is malfunctioning and costs more to repair than replace

Over on the left there is a small two-position slide switch with pictures of an open lock and a closed one. Slide the switch to the rear (Open lock) and close the cover.

1. Make sure the printer is turned on and the desired tractor is selected (the corresponding tractor arrow should be lit).
2. Open the upper cover.
3. Press the Top of Form button to enter top-of-form mode. The printer beeps once, and the Top of Form light turns on.
4. Use the Micro Feed buttons to feed the paper to the desired top-of-form position. The “A” on the ribbon protector shows you where the bottom edge of your first line of text will print. This position is based on the first printable line of text. If your software inserts a top margin of five lines, your text will actually print five lines below the top-of-form position.
5. Press the Top of Form button again to exit and save your new top-of-form position. Then close the top cover.
