More than pleased with my prurchase, very good product for the price.

This is a good quality scan of the service manual which includes an assembly diagram, block diagram, schematic, and parts list. Exactly what is needed to repair my KR-V55R receiver.

Excellent concise manual. All needed information was included. Typeface and diagrams were clear. Very fair price considering what others are charging. Many thanks

Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.

When the main switch turns on, the CPU checks the ac frequency for 500 ms. Then the CPU turns on the fusing lamp. When the thermistor detects the stand-by temperature (165 °C), the machine can start to print. When the thermistor detects the operating fusing temperature (180 °C), the CPU maintains this temperature using phase control. Phase control is the only type of fusing control in this machine.
7.7 OVERHEAT PROTECTION
If the hot roller temperature becomes greater than 230°C, the CPU cuts off the power to the fusing lamp. At this time, SC543 will be generated. Even if the thermistor overheat protection fails, there is a thermofuse in series with the common ground line of the fusing lamp. If the temperature of the thermofuse reaches 169°C, the thermofuse opens, removing power from the fusing lamp. At this time, the copier stops operating.
