7.2.3. Contact STR Roller to Accumulator Belt
The STR roller is in contact with the accumulator belt or released from the accumulator belt by the STR release lever linked with
the STR cam in the accumulator tension unit. The following indicates the STR cam, cam shaft and STR release lever in the
accumulator tension unit.
When the accumulator tension unit is in the Home Position, the STR roller is released from the accumulator belt because the top
end of STR release lever pushes the STR roller holder in the arrow (A) direction. When the cam shaft rotates, the cam rotates in
the arrow (B) direction. When the cam shaft rotates 180° (the status of accumulator tension unit is in the "Toner Transfer Position"),
the STR tension spring moves the STR roller supported by the STR roller holder in the arrow (C) direction, the gap (A) decreases
between the part (A) and surface of cam. As a result, the STR roller moves in contact with the accumulator belt. This contact is held
until the cam shaft (cam) rotates 270° (The FTR Roller Release Position). When the cam shaft rotates 90° (the status of
accumulator tension unit returns to the Home Position), the cam moves the STR release lever in the arrow (A) direction and
releases the STR roller from the accumulator belt.
