I have an OKI C9800.
After replacing the waste toner cartridge and cleaning the toner transfer belt. I reinstalled the belt mechanism, and the toner drum units. Upon restarting the printer, I keep getting a "342" error code that says that the cyan toner unit has not been installed correctly.
I have scrutinized every detail and cannot detect anything wrong with the installation of the toner unit. It is identical to the other toner units, and all the electrical contacts appear to be made when installed.
I can't detect any mechanical reason for this. However, when restarting the machine each time, the message screen shows a question mark for the toner level. I installed a new toner cartridge, but the same question mark appears in the cyan toner level indicator.
And after a few moments, the printer starts to do its prep cycle and then you can hear a very slight "clunk" and the the "342" code appears.
Any clues as to what might be happening?
Problem might be with toner recycle coil which runs around the back of the belt unit. as the cyan unit is the furthest down the line if any blockages occur it can back up and lift the drum unit up. check the square opening of the recycle unit on the cyan end. Make sure you change waste toner unit when prompted or you might break a gear (big job)

remove the toner/drums and transfer belt. on the right side is the reg rollers. there is a black arm and sensor the detects the paper weight etc there. that will control the paper sense errors, make sure it moves freeley, clear of paper, dust etc.
Hi - take the waste toner unit out and restart the printer. You'll now have a different error 'Check Waste Toner'. Open the front cover and put the waste toner back in. Let the printer go through the usual checks and hopefully all should be well.
In my experience this can be caused by not shutting the printer down fully before changing the waste toner. JohnnySheffield

Replace the HAL IC circuit

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.
