The pressure of the paper transfer belt is released as follows when the drawer unit is withdrawn or inserted, so that it does not interfere with the image transfer belt unit.

  1. The drawer unit lock motor [A] rotates the link (drive) [E].
  2. The link (drive) [E] moves the link (driven) [C].
  3. The paper transfer belt release cam [D] moves and the paper transfer belt [B] is released (separated from the ITB).

Note the difference between the effects of this motor and the paper transfer belt separation motor (described in the previous section). The paper transfer belt separation motor only moves the paper transfer belt a small distance from the ITB, to reduce shock jitter. The above mechanism moves the paper transfer belt completely away from the ITB.
