2.2.5 Fusing Process
2.2.5.1 Overview
In this process, the toner transferred to the paper in the transfer process is fused to
the paper.
For fusing, this printer uses the heat roller fusing system. The sheet with toner on
passes between the heat roller, which is heated up by the fusing heater lamp, and
the pressure roller. During this passage, heat and pressure are applied to
permanently fuse the toner to the paper.
(See “Figure 2-15”)
2.2.5.2 Fusing Temperature Control
TEMPERATURE CHANGE
See Figure 2-20 at right and Table 2-5 below for temperature change.
TEMPERATURE ADJUSTMENT CONTROL
During warming up, the fuser temperature is raised up to the predetermined
temperature.
Warming up control is carried out at power on, at opening and closing of the front
cover and at canceling of Pause mode.
In standby mode, the fuser temperature is kept at 125°C, a little lower than the
temperature during printing, to reduce power consumption.
The temperature adjustment mode at restarting of temperature adjustment control
(at power on, at opening and closing of the front cover or at canceling of Pause
mode) is determined depending on the previous mode and the fuser temperature.
In Pause mode (low power consumption mode), the fusing heater lamp is turned
off to reduce power consumption.
