SOURCE: toner sensor error on an Oki C3520 Laser

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.

A plastic thing was closing the sensor window. Open the window and you will solve the problem.

SOURCE: OKI C3400 printer keeps saying

Okay, I had the same problem with my C3300. I phoned the people i purchased from and this is what fixed it for me:

looking directly at the printer:
-open printer
-remove drum in question (the drum is what houses the toner cartridge) in my printer it is black.
-look on the right side of the drum & there is a little (approx 5mm x 5mm) hole that has a little panel that opens- push this up to open it.

-replace drum close the top and try printing.

I had to do this 2 times before it worked, but it worked.

It is more than likely that you have an incompatible toner fitted to the drum unit. Either a generic cartridge or b430 or b440 cartridge which is not compatible with b410's. Beyond that it may be a faulty drum unit. Hope this helps.

Trata esto:
When installing the C3400n printer, or when replacing the toner cartridge, be sure to fully insert the toner cartridge into the image drum, and make sure the blue lever is pushed ALL THE WAY toward the back of the printer (fully locked position). If it is not fully closed (locked), a "toner sensor" or "toner empty" message may result. Note: (Picture at bottom shows incorrect position of locked toner cartridge that may result in either of these messages).

Installation Procedure of Image Drum and Toner Cartridge:

          0.408?openelement&fieldelemformat=gif
    >> Insure the toner is fully locked, see photo below showing the correct and incorrect positions of the locked toner cartridge.

CORRECT (Fully rotated to lock position)

INCORRECT (Not fully rotated to lock position)

Toner sensor error


take out the magenta cartridge. and make sure the edges are clean. There are little metal pieces on the sides where the sensor reads the cartridge. Also, make sure the "lock" on the cartridge is locked.

Hi moneybaggz52:
Here is your problem.

The printer can display any one of the following errors:

543K: TONER SENSOR ERROR

540Y: TONER SENSOR ERROR

541M: TONER SENSOR ERROR

542C: TONER SENSOR ERROR
Cause:
This generally can be caused by two things.

1. The toner cartridge lock lever is not in the correct position.

2. The Transfer Belt lock levers are not in the correct position.
Resolution:

Check the appropriate toner cartridge lock lever (Shown below) and make sure that it is in the correct position.
