2.9 IMAGE TRANSFER AND PAPER SEPARATION

2.9.1 OVERVIEW

7
Instead of using a transfer corona or a transfer roller, this machine uses a transfer
belt unit. The transfer belt unit consists of the following parts.
1. Contact lever
2. Transfer belt
3. Drive roller
The belt has a high electrical resistance, so it can hold a high positive electrical
potential to attract toner from the drum onto the paper. Also, the electrical potential
attracts the paper itself and helps to separate the paper from the drum and to carry
the paper upwards. The pick-off pawl ensures that the paper separates from the
drum.
The transfer belt cleaning blade removes toner from the transfer belt to prevent the
back side of the paper from being stained.
