Temperature Control
Just after the main power switch is turned on, the CPU turns on the fusing lamp to
obtain a fusing temperature of 175°C (Main fusing lamp), 165°C (Sub fusing lamp)
for the first 60s, or for the first three consecutive pages of printing, whichever
comes first. After that, the machine keeps the fusing temperature at 175°C for the
first 20 consecutive pages of printing. Then the fusing temperature is kept at
165°C.
The three-page and 60-second limits can be adjusted with SP1-105-8 and -9.
Note that the fusing temperature is higher if the user uses special paper in the 2nd
tray or thick paper mode from the bypass tray (! 2.8.9).
