'928 Fatal Error message' on OKI C5550MFP

Just to confirm that Jeff Hughes is correct. 928 does refer to paper wrapped around the fuser rollers making the thermistor see nothing hence the 928. If there is no paper in the fuser then it will need to be replaced. Remember to turn the machine off when removing or replacing the fuser.

it means FUSER MOTOR LOCK ERROR call a tech or you could try replacing the fuser motor

Error 928: Fuser Motor Lock Error An error was detected with Fuser Motor rotation by overload. If rebooting the machine does not improve the symptom, you need to check the Fuser Unit.

That particular error indicates a fuser failure. Try turning off the printer and re-seating the fuser. If this does not clear the message then the fuser needs to be replaced. With such a low number of prints warranty should cover it.

Must have Engine (fatal) and Jam Error logs display on the Control Panel or listed on ..... 041. paper jam. switch off the printer, remove its cartridge, look for paper jam or piece of paper jam in the rollers, clean it, place cartilage properly, switch ON the printer. it will work.

paper jam is a main issue in printer when you clear the paper jam normally a tiny piece of paper falls into the printer and the printer get stuck again to clear the printer of tiny piece remove the toner and use a light blower and blow away the piece of paper this should be done only after removing the power and the usb from the printer after cleaning connect the power and the usb and restart your computer

I had a paper jam and removed the jammed papers. The paper jam cleared and then the Fatal Error 980 appeared. OKI C5500 printer

Have you checked to see if there is any paper jammed in the sensor, at the back in the 150-sheet feeder assembly, if not the paper could be stuck the 150-sheet assembly

What is the status of your fuser unit and on what paper settings are printing on? When last have you cleaned tour machine?

No reset need to fix fault then clears...check toner carts are secure on drums, all their contacts are clean,

Replace Toner Cartridges with Gen OKI new ones... are you using non oki product? Cause Toner carts, thats where I would start looking cause the error is the machine not receiving correct information from a little chip built into the toner cartridges to allow operation to begin.
