2. Operating instructions
2.2 Printing process
The paper fed from tray 1 or tray 2, tray.3 is transferred by feeder roller, resister roller
L, and transfer roller. It is transferred by MPT paper feed roller and resister roller U
when the paper is fed from MPT. After that, the paper on the belt passes through the
electrophotography process of KYMC, and sequentially the unfused toner image is
generated on the paper. And then, the toner is fused by heat and pressure when it
is passed through the fuse unit. After fusing, the paper is delivered to the faceup or
facedown stacker by utilization of different delivery methods by opening or closing the
faceup stacker.
The operation of single-sided printing is described as above. The operation of duplex
printing is described as below.
As for the duplex print, the paper passed the fuse unit after initially back printing is drawn
into the Duplex unit by separator DUP. The paper entered into the paper reversing path is
transferred from the paper reversing path to the inside of Duplex by reverse operation of
reversal roller. The paper passed over the inside of Duplex is fed from paper feed path of
Duplex by the transfer roller set in the transfer path of Duplex inside, which is shared with
the same paper feed path from the tray. The following operation is same as single-sided
printing with paper feeding from the tray.
