OKI C8600 Printer Toner Sensor Reset

Hi


This error comes up when the printer detects that the toner of particular color is missing. This indicated that the indicated color toner is missing from the printer(eg-- C = Cyan, Y = Yellow, M = Magenta, K = Black).

C5150 may face a toner sensor error after installing used sets of toner cartridges and sometimes even after installing new toner cartridges as well. This error can be bypassed. This can be disabled by following these steps---

1. Turn machine on while pushing and holding the (+/-), menu buttons at same time.
2. Menu window will show OKI USER.
3. Scroll to Engine Dialog Mode is indicated Push Enter button.
4. Diagnostic Mode xx xx xx S Mode is indicated.
5. ( = 2 ) . Press (- or +) button until “ENGINE - PARAMETER SET =2” is displayed.
6. Push Enter button.
7. TONER SENSOR - ENABLE is displayed.
8. Push Enter button.
9. Press (- / +) TONER SENSOR = DISABLE is displayed.
10. Press ON LINE CANCEL buttons at same time.
11. (*) is displayed.
12. Restart the Printer.

Buy a pack of 10 x .062A (1/16A) pico fuse RS part No 738-3062. Switch off printer. Remove the drum and toner together from the drum slot to be reset. Carefully crimp the legs of the fuse around the contact wires on the right side of the drum slot. Make sure fuse legs are making a good connection to the wires and aren't touching the frame. switch on printer and allow it to detect the absence of the drum. Switch off printer and carefully remove the now blown fuse. Re-install the toner and drum assemnbly. Drum life is now reset. see pic:

try this:

1.Press Menu = printer displays "Paper Menu"
2.Press Next 4x = printer displays "System Menu"
3.Press Select 1x = printer displays "Factory Defaults"
4.Press Next 7x = printer displays "Reset Toner Life"
5.Press Select 1x = printer displays "Resetting Toner Page Count"

Check the little switch/door on the right hand side of the drums.
This has worked successfully for me.

Symptom:
After replacement of a C3530 Image Drum, the message, "Toner Sensor Error" is displayed.






Cause:
The plastic shutter in the ID is fully or partially covering the toner sensor window.




Resolution:
Move the cover upward to allow for the sensor to become fully exposed prior to reinstalling the drum.

Clean the sensor. Reset the printer and that should help you with this error. If thet doesn't work replace the toner cartridge.

Worked for me when I had the same error. Hope it helps.

sensor window on the drum is closed - or the r/h side of the printer has a sensor that needs cleaning.

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.
