General Procedures and Information
6-12 04/07 Phaser 3200MFP / Workcentre PE220
Feeding mechanism
The universal cassette automatically loads paper while the manual feed supplies a single sheet
of paper each time. The cassette has a friction pad which separates each paper to ensure single
sheet feeding. A sensor checks when the paper cassette is empty.
- Feeding Method: MP Cassette Type
- Feeding Standard: Center Loading
- Feeding Capacity: Cassette -150 sheets (75g/m2, 20lb paper standard) - PE220
- 250 sheets (75g/m2, 20lb paper standard) - Phaser 3200
- Manual feed -1sheet (Paper, OHP, Envelop, etc.)
- Paper detecting sensor: Photo sensor
- Paper size sensor: None
Transfer Assembly
The transfer assembly consists of the pre-transfer lamp (PTL) and the Transfer Roller. The PTL
shines a light onto the OPC drum. This lowers the charge of the drum’s surface and improves
transfer efficiency.
The transfer roller transfers toner from the OPC drum surface to the paper.
- Life expectancy: Over 50,000 sheets (at 16~30°C)
Driver Assembly
- Gear driven power unit. The motor supplies power to the paper feed unit, the fuser unit, and
the toner cartridge.
Fixing Part (Fuser)
- The fuser consists of the heat lamp, heat roller, pressure roller, thermistor, and thermostat. It
adheres toner to the paper using pressure and heat.
Temperature-Intercepting Device (Thermostat)
The thermostat is a temperature sensing device, which cuts off power to the heat lamp when the
heat lamp or heat roller overheats.
Temperature Detecting Sensor (Thermistor)
The thermistor detects the surface temperature of the heat roller. The information is sent to the
main processor which regulates the temperature of the heat roller.
Heat Roller
The surface of the heat roller is heated by the heat lamp. As paper passes between the heat and
pressure rollers, the toner is melted and adheres to the paper. The surface of the roller is coated
with Teflon to ensure toner does not stick to surface of the roller.
Pressure roller
The pressure roller is mounted under the heat roller and is made of a silicon resin. The surface of
the roller is coated with Teflon to ensure toner does not stick to the surface of the roller.
