The content of the manual was not found on the Internet and was a hard find. I check the net for 5 hours until I came across this web-site. When I did find the book it Auto loaded into my IPAD PDF shelf for books for review at anytime. Overall I am satisfied with the book and it answered all my questions. This repair book is obsolete because the product I bout it for is pretty old. Thanks for the help with the download and even having the manual. Thanks 73's K5HRD

It was magic after so many years to still be able to source this info. It was equally amazing to return my Pioneer receiver to it near new sound quality AFTER NEARLY 30 YEARS! Thank you for this ability!

Easy and secure way to get a complete service manual of a vintage hifi component. Only some parts of the print copy are dificult to read. Nice price!
TONER SUPPLY
4 July 1996
6.3.3 Fixed Supply Mode If 4 is selected in SP30, the TD sensor is not used for toner supply control. A fixed amount of toner is supplied at every copy cycle. The toner supply amount is determined by the SP32 setting. 6.3.4 TD Sensor Check and Toner Supply Timing During every copy cycle, the TD sensor voltage is monitored for three seconds after the machine starts developing the image on the drum. The CPU checks the voltage every 40 ms and stores the second highest voltage of every 250 ms period. Then the stored voltages during the three seconds are averaged, and the average is used as the TD sensor value for the copy. The toner supply clutch on time for detect supply mode using TD sensor output depends on this value. If the machine determines that toner needs to be added, the toner supply clutch turns on just after the trailing edge of the copy paper passes the transfer corona unit. If the copy paper is shorter than A4/LT size, the clutch is energized for 3 seconds after the machine starts developing the latent image. 6.3.5 Abnormal Condition in Toner Density Detection If the calculated value of the TD sensor goes below 0.2 volts, the CPU determines that the toner density detection is abnormal. The CPU changes from the detect supply mode to the fixed supply mode. At the same time, either the Auto ID indicator or the selected manual ID level starts blinking, and the machine can be operated. Under this condition, the machine will not perform the toner end detection. If the value recovers above 0.2 volts, or the main switch is turned off and on, this condition is canceled and the toner density detection will recover to the previous settings.
