correction. The area that is covered with the bronze plate does not generate the same
amount of heat as other parts. The temperature correction for paper size is used for seven
paper sizes (A3, B4, A4, B5, A5, B6, and A6). The ferrite roller motor [C] rotates the ferrite
roller [A] to the correct position for the selected paper size.
The ferrite roller HP sensor [D] detects when this roller is at home position. The ferrite roller
is moved to its home position at the end of every job.

6.9.4 PRESSURE RELEASE MECHANISM

The pressure levers [A] put the proper pressure to the nip between the pressure roller [B]
and fusing belt [C]. When releasing these levers, the pressure roller moves away from the
fusing belt. If a paper jam occurs in the fusing unit, releasing these levers make jammed
paper easily removed.
