Fusing paper transport control

• The 2nd image transfer roller transports paper onto the fusing roller (fusing belt, fusing
pressure roller).
• The paper exit sensor installed downstream of the fusing roller (at the right door/duplex
section) detects the paper fed from the fusing roller.
• The fusing motor is deenergized when the paper which has been transported from the
2nd image transfer roller and moved past the fusing roller reaches a predetermined posi-
tion. The switchback motor starts rotating forward when the paper that has moved past
the fusing roller reaches the predetermined position and the exit/switchback roller con-
nected by the drive belt rotates forward.
• The switchback motor is deenergized when the paper which has been transported from
the fusing roller and moved past the exit/switchback roller reaches a predetermined posi-
tion.
For duplex printing, the switchback roller is rotated backward to transport the paper into
the duplex section.

Paper separation mechanism

• Paper separator claws (at five places) function to separate the paper which has under-
gone the fusing process reliably from the fusing belt.
