Complete manual with clear schematic diagrams and printed circuit board layouts of two variants of the headset and the transmitter an old and a new version.
Also shows how the headset and the transmitter is opened and how transmitter and receivers can be adjusted and where to measure.
I had no problems to repair the headset using this service manual.
This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.
Mi spiace per non poter scrivere in inglese... ma sono veramente soddisfatto del servizio offerto. Grazie..!!

Basics
Sensing System Theory - 5 cassette-fed and manual-fed paper. If the paper does not reach the top position of this sensor in the required time, the printer determines that a pick-up delay jam has occurred. Winding paper sensor PS303 detects the passage of paper from the photosensitive drum to the fuser. If the paper does not pass this sensor in time, the controller board determines that a jam condition exists. Paper delivery sensor PS301 detects the passage of paper through the fuser assembly. If the paper does not pass this sensor in time, the controller board determines that a jam condition exists.
