Self-Diagnosis Information

[Wez]

Does anyone know of a list for self-diagnostic tests to run through one of Toshibas digital machines to find abnormal readings, outputs or counters?

I'm running a 311C specifically but some general codes for any full colour digital machine would be useful. Or any useful codes to run through a machine to get an idea of parts that may need replacing/cleaning etc.


I'm specifically after toner sensor information. I've run several 03 Codes on my machine but I have no material to explain the significance. In case anyone here can assist..
Auto Toner Sensor Y: 255 (8 bit scale)
Auto Toner Sensor M: 145 (8 bit scale)
Auto Toner Sensor C: 221 (8 bit scale)
Auto Toner Sensor K: 255 (8 bit scale)
I have a problem with Y at the moment and the results seem very varied. a 255 sensor on Y suggests too much but K has the same and them M has a much lower value and both M and K and printing well.

Anyway just wondering what people here recommend investingating in a machine.
