Question about OKI C Office Equipment & Supplies
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).

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.

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.
