OKI c5750 - fatal error 918

OKI c5750 - intermittently get a fatal error 918. It's to do with the duplex unit (apparently). Sometimes it clears if I switch off and back on, and sometimes I have to pull duplex unit out to print single sided. So far it's always started up again (eventually) but I need the duplex (it's why I bought it).

SOURCE: laserjet 4250 not dupexing

Had this same issue on my 4250dtn. The solution in my case was that both paper trays were set to "custom". This is a small lever on the right side toward the back of the paper tray. Even HP was stumped on this. Hope this helps.

SOURCE: says a front paper jam but no paper jammed any where

Your paper feder belt has ink on it and will not feed the paper. Remove the rubber belt and clean it good and clean and use compressed air on the printer tray area. If this does not work open the front feeder tray and set your computer to print from it. After about 500 copys it will normally have c leaned itself and be ready to feed from the main roller.

Oki c5200 fatal error 121


We had a similar problem with an Oki C7300. It was reading "Fatal Error 121" on the display.

We fixed it by simply unplugging the printer from a surge strip and plugging it into the wall directly. After that, the error went away and has not come back.

Oki 9800 230 fatal error


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.
