Theory of Operation
4. Miscellaneous Paper Functions
A paper arrangement function uses a stopper roller and a weight without
an electric actuator. It also includes an additional paper separating
function, a driving control function, and a multi feeding prevention
function. The Feed Roller transfers paper along the paper path and is also
part of jam detection.
Transfer Roller Assembly
The transfer subsystem consists of the Pre-transfer Lamp (PTL) and the
Transfer Roller. The PTL exposes the drum surface after the latent image has
been developed to lower surface potential of the drum. This provides
enhanced transfer efficiency.
The Transfer Roller provides a high positive potential on the back of the print
media
. This potential attracts the negatively charged toner image from the
drum and deposits it on the surface of the print media.
The transfer voltage is controlled by PWM (Pulse Width Modulation). When
the pap
er enters the Transfer Roller, the resistance value of the Transfer
Roller will change due to the surrounding temperature of the printer. If the
temperature changes, a new voltage level is created through an AD converter.
Fuser Assembly
The Fuser Assembly contains the entire Fuser Subsystem and is a field
replaceable unit. The Fuser Assembly contains the following components:
■ Heat Element and Heat Roller:Two quartz lamps operate as the heating
elements, which generate the heat inside the Heat Roller. The Heat Roller
melts the toner so it adheres to the paper.
■ Pressure Roller: Provides pressure on the opposite side of the print
media so the Heat Roller can embed the melted toner in the media.
■ Thermistor: Monitors the surface temperature of the Heat Roller. This
information is used to control the heat lamp and thus keep the Heat Roller
at the correct temperature.
■ Thermostat: Prevents overheat damage when unexpected system faults
occur.
