Paper jam light keeps flashing - OKI B4100 Laser Printer

you either have a paper jam or the scanner module has jammed. open the printer and check the paper path for possible jams. then open the scanner lid and make sure the scanner light bar is in the home position at the end of the scanner deck and not stuck mid path.

1. there is a sensor at the end of the printer which shows paper jam recovery. the sensor of your printer may be jammed. clear the jam and it will work. 2. if not, there may be a small piece of paper near the sensor of your printer. clear it.

I hope this will help you :)

hi,clean any sensor & clear any hide misfeed sheet.send me result.
thank you.

There will still be some scrap of paper in the machine. Get a torch and get in there. It's the only way, unless you call tech guy

When the orange light is flashing, either paper jam or ink problem is happening.Try unloaging & reloading the stack of paper in the main tray. Remove & reinsert ink cartridges in the printer. You may also clean the contacts of the cartridge and inside the product.

check all paper paths for little pieces of paper
