 TC-D5PROII SONY Service Manual by Dmitry Khazov;
Quick service response. A useful and very rare service manual with all details. I recomend this service.
 TAF444ES SONY Service Manual by Stanislaw Rybakowski;
I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening. This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual. The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
 KM2500 JVC Service Manual by Ryan Supak;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual! I'd definitely use owner-manuals.com again.

Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 R-945 SHERWOOD Service Manual by Bruce Rogers;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.

Summary of Product

4.2.6 Fuser
There are two methods of fusing toner onto the paper: the existing heat lamp process and the Q-PID process developed by Samsung. ML2250 export models, both 110V and 220V, use the heat lamp process. This consists of a heat lamp, heat roller, pressure roller, thermistor and thermostat. By use of heat and pressure toner is caused to melt and adhere to the paper surface in order to complete the printing process.

4.2.6.1 Thermistor and Thermostat
The thermistor is used to detect the temperature of the heating unit and feeds this information into the main processor If the heat lamp becomes too hot the Thermostat cuts off the power to the lamp in order to prevent over-heating and any potential fire hazard is removed.

4.2.6.2 Heat roller
The heat roller transfers the heat from the heat lamp to the paper. The surface of the heat roller is coated with Teflon so that toner does not stick to the surface.

4.2.6.3 Pressure roller
A pressure roller mounted under the heat roller is made of a silicon resin and the surface is also coated with Teflon. When a paper passes between the heat roller and the pressure roller the toner powder is meted and adheres to the surface of the paper permanently.

4.2.6.4 Safety features
To prevent overheating - 1st protection device: Hardware cuts off when overheated - 2nd protection device: Software cuts off when overheated - 3rd protection device: Thermostat cuts off mains power to the lamp. Safety device - Fuser power is cut off when the front cover is opened - LSU power is cut off when the front cover is opened - The temperature of the fuser cover's surface is maintained at less than 80ºC to protect the user and a caution label is attached where the customer can see it easily when the rear cover is opened.

4.2.7 LSU (Laser Scanner Unit)
This is the core of the laser printer. It converts the video data received from the computer into an electrostatic latent image on the surface of the OPC drum. This is achieved by controlling the laser beam and exposing the surface of the OPC drum to the laser light. A rotating polygon mirror reflects the laser light onto the OPC and each side of the mirror is one scan line. The OPC drum turns as the paper feeds to scan the image down the page. The /HSYNC signal is created when the laser beam from LSU reaches the end of the polygon mirror and this signal is sent to the controller. The controller detects the /HSYNC signal to adjust the vertical line of the image on paper. In other words after the /HSYNC signal is detected the image data is sent to the LSU to adjust the left margin on the paper.
