In case your unit is already in Shipping Mode (the correct default setting), then the problem could be with the toner cartridge itself, or the printer unit. If multiple cartridges do not reset the counter, the unit may need to be serviced. Contact the Oki Data for additional troubleshooting.
Resetting Instruction:
1) Power on printer while holding both the + & - buttons simultaneously; release when “Oki user” is displayed.
2) Press + or – until “Engine Diag” Mode is displayed; press Enter and Diagnostic Mode xx.xx.xx. will be displayed
3) Press and hold both Enter & On-line simultaneously until “Eng Diag Level3” is displayed
4) Press + or – until Local Parameter Set is displayed; release and press Enter
5) Press + or – until it displays Factory Mode; if it displays Factory Mode Twice with an asterisk next to the one then it is Factory Mode; Press + or – until it displays Factory Mode & Shipping Mode on the display; then press and hold On-line & Cancel simultaneously; when it stops blinking an asterisk should be displayed next to Shipping Mode, which becomes the default mode.
6) Power printer off and then on in order to complete the procedure.
If by any chance changing to shipping mode does not resolve the problem of resetting the counter, please contact Oki Data for additional troubleshooting.
