- Very good scan quality, PERFECT!
- Sehr gute scan Qualitaet, empfehlenswert!

Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.
3. OPERATIONS AND TIMING
4. Detecting Overheating on the Fixing Heater End
The rear end of the fixing heater is equipped with a sub thermistor (TH2) to check for overheating. This is to prevent overheating and consequent damage to the fixing film which could occur when continuous copying is performed using copy of B4 or smaller in size. (Overheating tends to occur where the drum is not in contact with paper.) When the output of THE2 exceeds 250°C, the machine increases the sheet-to-sheet distance to accelerate heat discharge of the fixing heater, thereby preventing overheating. Copying operation is continued with the increased sheet-to-sheet distance even after the output of TH2 falls below 250°C. If overheating continues after increasing the sheet-to-sheet distance and the temperature exceeds 260°C, the on-going copying operation will be stopped and the power will be turned OFF. (E001 will be registered.)
5. Protection Mechanisms
The machine is equipped with the following protection mechanisms to prevent malfunction of the fixing heater: a. Thermistor (TH1, tH2) 1. The microprocessor on the DC controller monitors the voltage of the thermistor (TH1, TH2); if it detects overheating of the heater or error low temperature, it stops the power to the heater and turns off the power. (E000 through E003 will be registered.) 2. If the error temperature detection circuit finds that the output of TH1 is 250°C or more or that of TH2 is 260°C for 0.2 sec or more, the heater error detection signal (HTNG) will be issued to turn off the relay, stopping the power to the fixing hater and turning off the power. b. Thermal Fuse (FU1) When the temperature around the thermal fuse reaches 226 °C and the condition remains for a specific period of time, the thermal fuse will melt to stop the power to the fixing heater. c. Heater ON Detection Circuit (200V model only) The period of time during which the fixing heater drive signal (HTRD) remains OFF is monitored; if an error is detected, the power is turned OFF. (E004 will be registered.)
