Clear and complete service manual. Easy now to restore my old Kenwood KD-1500.
Thanks a lot.
 ;
Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !
 ;
Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.

This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.

5 stars on this manual since it is the complete version, not the half manual you find free for download all over the web. Good job.

6.13.8. PRINT TIMING SENSOR
This sensor detects whether the recording paper is at the printing position. When the recording paper is detected, the shelter plate lets the sensor light pass. So the photo-transistor turns on, and input signal of IC604-113pin becomes low level. When the recording paper is not detected, the shelter plate closes the sensor light. So the photo-transistor turns off, and input signal of IC604-113pin becomes high level.
Paper exits No paper
Photo-transistor ON OFF
Signal (IC604-113pin) Low level High level
6.13.9. DOCUMENT SENSOR
This sensor detects whether a document is set in ADF or not. When a document is set in ADF, the shelter plate closes the sensor light. So the photo-transistor turns off, and input signal of IC604-115pin becomes high level. When a document is not set in ADF, the shelter plate lets the sensor light pass. So the photo-transistor turns on, and input signal of IC604-115pin becomes low level.
document exits No document
Photo-transistor OFF ON
Signal (IC604-115pin) High level Low level
