4-4-2-6. Anchorage unit
The toner transferred on to the paper is at the electronically low state and it can be easily scattered. Considering this fact, we
used heat (180°C) and pressure (4kg) to fix the toner on the paper permanently. Then the image formed will remain on the
paper permanently. Heat roller transfers the heat from the heat lamp inside to the paper. The surface of the heat roller specially
coated with Teflon repels toner melted by the heat from the surface.
The pressure roller on the bottom of the heat roller is made of silicon resin and its surface is also coated with Teflon. The ther-
mistor of the fixer unit detects the surface temperature of the heat roller and feeds this information back in order to retain 180°C
while printing and 135°C, while on standby. The thermostat is used as the secondary safety device and it prevents overheat
by shutting the main power when the heat lamp
is overheated.
4-4-2-7. Exit
After the digital picture process is finished, the printed paper will come out of the set through the exit sensor. The signal detect-
ed will be transferred to the engine and provide the position information. If the actuator and the sensor do not work normally,
the system will display "Paper Jam 2 Error".
