Summary of product
Service Manual
4.2 System Layout
4.2.1 Feeding section
Paper for the machine is supplied from a universal cassette or from the manual feeder, for single sheet
feeding. The cassette contains a friction pad, to separate the paper and prevent multi-sheet feeding.
There is a sensor to detect the presence of paper in the cassette.
- Feeding Method: Universal Cassette Type
- Feeding Standard: Center Loading
- Feeding Capacity: Cassette-250 sheets (80g/m
2
, 20lb paper standard)
Manual 1 sheet (Paper, OHP, Envelope, etc.)
- Paper detecting sensor: Photo sensor
- Paper size sensor: None
4.2.2 Transfer Ass’y
The Transfer Ass'y consists of the PTL (pre-transfer lamp), OPC Drum, and the Transfer Roller. The PTL
lights the surface of the OPC Drum, reducing the charge on the drum surface to improve transfer efficiency.
The Transfer Roller transfers toner from the OPC Drum surface to the paper.
- Life span: 60,000 sheets (in 15~30°C)
4.2.3 Drive Ass’y
The Drive Ass'y is a motor driven gear unit, that drives the paper feed, the Fuser, and the distributing unit.
4.2.4 Fuser
The Fuser consists of the Heat Lamp, Heat Roller, Pressure Roller, Thermistor, and Thermostat. It melts
the toner to the paper using pressure and heat to complete the printing job.
4.2.4.1 Thermostat
The thermostat is a temperature-sensing device, that cuts off the power to prevent overheating or a fire
when the heat lamp or the heat coil of the heat roller becomes too hot.
4.2.4.2 Thermistor
The Thermistor detects the surface temperature of the heat roller. The information from the Thermistor
provides the on/off control that maintains the selected temperature of the heat roller.
4.2.4.3 Heat Roller
The heat roller transfers the heat from the heat lamp coil to the surface of the paper.
The melted toner cannot stick to the Teflon coated heat roller.
4.2.4.4 Pressure roller
The pressure roller mounted right under the heat roller is made of the silicon resin. The toner fuses onto
the paper when it passes between the heat roller and the pressure roller.
