7.3.5 Transfer Belt Cleaning

After the toner image on the transfer belt is transferred to the paper, the

toner remaining on the transfer belt is removed by the cleaning blade [A],

which is a counter blade system. The entrance seal [B] prevents the

removed toner from falling onto the paper transfer unit or paper.

The cleaning solenoid [C] contacts and releases the blade and seal from the

belt. The timing for contacting the cleaning blade and entrance seal to the

transfer belt depends on the paper size. This is because contacting the

cleaning unit to the transfer belt changes the tension of the transfer belt, and

this causes a discrepancy while the image is being transferred to the belt.

1. A4/Letter Size or Smaller (216 mm or smaller in the subscan direction)

The cleaning blade and the entrance seal contact the transfer belt just

after the last color for the copy has been transferred to the transfer belt.

The cleaning blade and the entrance seal are released from the transfer

belt just after the first color for the next copy has been transferred to the

transfer belt.

2. A3/Double Letter Size (larger than 216 mm in the subscan direction)

The cleaning blade and the entrance seal contact the transfer belt just

after the toner image for the copy has been transferred to the paper. The

cleaning blade and the entrance seal are released from the transfer belt

just after the first color for the next copy has been transferred to the

transfer belt.
