Ordered service manuel for a hard to find plasma tv - your company made it easy to find and purchase - I will use you again
Thanks for your help
 ;
This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.
;
This service manual for the Kenwood KT-990D was reproduced really well ,is very legible and manual is complete.Combined with the low price paid,in the future,I will be checking Owner-Manuals.com any time I need a manual.
;
When I purchased this manual I had my doubts regarding the quality as the price was so reasonable as compared to other outlets.
The manual itself is of high standard the print is very clear as are the diagrams. Obviously with the diagrams one has to zoom in otherwise it is to small to be able to read.
Overall I am very pleased with the company who delivered as they said and with the manual they supplied.
I occasionally require a manual and now having registered with this company I shall order from them in the future.
;
I was at first dubious about payiong for downloaded manuals but having done so, I was extremely impressed with quality of the two manual I ordered, well worth the small price I paid.
I would highly recommend these to my friends.
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.
