signal is sent.
The interval from when image formation starts to when paper is delivered.
Different temperature control table and lighting heater are used depending
on the paper size, paper type, and temperature of the edge of the fixing
roller.
Print
Transmission sequence differs depending on the edge temperature of the
pressure roller at print end.
• Below 180 deg C: transferred to the post rotation
• 180 deg C or higher: transferred to post-rotation 1 -> post rotation 2
After 5 sec from when the paper goes through the fixing nip, the pressure

roller/external heat roller is disengaged and it stops.
The fans cool down the pressure roller.
If the edge temperature of the pressure roller drops by 10 deg C from the

entry temperature (180 deg C or higher), the machine goes to the post-
rotation 2.
The fans cool down the pressure roller.
Last Rotation 2 If the edge temperature of the pressure roller drops below 165 deg C, the
machine goes to standby mode.
