It is pretty good. The schematics were covered all components, the manual also provide the parts list . It's useful for the trouble shooting.
 ;
Very fast service, best quality of the service manual and the schematics
;
This service manual of the old video cassette recorder VT-LC50EM is very good readable even the tiniest numbers (i.e. IC-pins). The circuits are very clear. Many details of the schematic are very good described but in GERMAN language. Many schematic details - but complete at all. Common background information of several details are enclosed and physical knowledge of the TFT liquid crystal display for example. The manual lacks PCB drawings. If you understand german I would recommend this manual for you.

Hi, this is a very clear manual, nice copy, not quite up to the standard of the very best available but better than many others. I think the price was especially fair for a hard to find manual and I would certainly use this manual seller again. Recommended.

This schema available for me in good condition. I would highly recommend.

4. Fusing section
After transfer, toner on the paper is heated and fused in the fusing section. This machine employs the heat roller pressure pad system for fusing.
Heat roller:
This roller is made of aluminum tube (14mm diameter and 0.5mm thickness) coated with teflon which has a high friction coefficient (for greater transport force) and a high separation capacity. The 400W halogen lamp is used. This spring presses the heat roller with a 690g pressure on one side. The pressure pad is covered with the teflon sheet for smooth paper transport when fusing. The employment of the pressure pad and the teflon sheet allows fusing in a low pressure (only 690g on one side). Two thermistors of chip type with good response are used to respond to rapid heating (rapid warm-up of about 8sec) of the heat roller. One is in close contact with the heat roller to detect the heat roller temperature. The other is separated from the heat roller to detect the ambient temperature.

Thermistor:
Temperature fuse 1: Temperature fuse 1 is installed to the fusing cover. It blows off when the ambient temperature of the fusing cover rises abnormally (132�C). Temperature fuse 2: Temperature fuse 2 is in close contact with the heat roller. It blows off when the heat roller temperature rises abnormally high (187�C).

B. Operations
This machine uses two thermistors; one is in close contact with the heat roller to detect the heat roller temperature (Thermistor 1 in Fig. 12-24), the other is separated from the heat roller to detect the ambient temperature (Thermistor 2 in Fig. 12-24). The heat roller temperature is controlled by these both data. (Temperature control is performed by turning on/off the heater lamp.) For example, the heat roller temperature is controlled to 155�C when the ambient temperature is 25�C. When the ambient temperature falls, the heat roller temperature is raised. When the ambient temperature rises, the heat roller temperature is lowered.
