Good scan, great price, but almost the same with the SV260 service manual.

This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.

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
