A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.
;
Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
;
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

5.4.11.5. Toner Empty Sensor Circuit
Toner empty sensor detects the shortage of toner. IC006 ( CPU ) sends the nTECTL ( pin7, IC006 ) signal to Q008. When the nTECTL is low level, transistors Q008 and Q004 are turned on. and LED D517 emits light. If the toner is shorted ( empty ), the light from LED D517 passes through the lens of the Toner Cartridge. When the photo transistor PI451 receives the light, the PI451 is turned on, and the TESEN ( pin4, IC004 ) signal becomes low.
5.4.12. Fan Control Circuit
FANCTL: 1. Full Power Mode When FANCTL signal ( pin 6, IC006 ) is high, pin 14 of IC003 goes high, transistors Q019 and Q022 are turned on. This supplies +24V Power to Fan motor and rotates the Fan. 2. Reducing Power Mode ( Quiet Mode ) Pulse signal ( see below ) is output from pin 6 of IC006.
This pulse signal is integrated by R114 and C097. Voltage of ( A ) is stabilized at approx. 2V. When the voltage of ( B ) is lower than the voltage of ( A ), pin 14 of IC003 goes high, Q019 and Q022 are turned on, then the voltage of ( B ) increases. When the voltage of ( B ) is higher than ( A ), pin 14 of IC003 goes low, Q019 and Q022 are turned off, then voltage of ( B ) decreases. Thus the voltage of ( B ) is controlled almost same as the voltage of ( A ) ( = approx. 2V ). Since the resistor network of R129 and R130 divide the voltage of ( C ) into 1/8, the voltage of ( C ) is controlled approx. 16V ( = 2V x 8 ).
FAN Control Mode Mode Warm Up Printing Others FAN Power Full Full Reduced
FANERR: This signal is used for detecting whether the rotation of fan motor is proper or not. When the fan motor is not rotating properly, this signal is two pulses per revolution with 50% duty cycle. At locked rotor, this signal is held at high (or low) 75
