I have replaced a few magenta IUís on the C277ís lately where the toner collect screw is seized up at the front due to it being jammed solid with toner and in some cases, the gear at the rear of the unit shears off. At first, we thought it might be a problem with the waste toner bottles and have also checked the filter/fans but so far it is a bit of a mystery. Has only one else come across this issue?

First time I hear of this problem, are you using original toners? Magenta IUs where over life or premature failing?

The machines are using genuine toner but I have found out that 2 out of 3 the machines have had second hand IU's fitted for previous faults so this might explain things and the other machine had done about 30k before the magenta IU had been replaced.
