Hi all
We have a weird one here.
This machine worked well from new - for about a week, then it stopped and demanded black toner (with a full bottle still installed).
Some testing was done with these results:
- When the machine is standing in the add toner condition and the front door is opened and closed, the black bottle turns for one cycle and then stops. One can here the lower toner supply motor pulse as if it is trying to supply toner, but the bottle does NOT turn.
- When doing a output check on the black toner motor, it turns.
- Have replaced the IOB with a known working one - no improvement
- When testing the black pcu in a known working machine, it tones up
Now my question is..... how now?? The toner supply logic surely comes from the IOB?? We have flashed all the latest firmware as well in the hope that this will help - no improvement.
Someone suggested that I replace the toner sensor that is attached to the toner supply assembly (similar to the ones on the spc430 toner supply assembly) as a last resort.
I would appreciate any help in this regard.
