2. Operational explanation
2.2 Printing process
The paper fed from Tray 1 and Tray 2 is conveyed by feeding roller, conveying roller, and resist roller.
When feeding paper is from MPT, it is conveyed by MPT, feeding roller, and resist roller. After that the
feeding paper that is conveyed by image drum and the nip part of transfer roller forms toner image
on the paper through electrophotographic process. And then, the toner on the paper is fused by the
heat and pressure as the fuser unit passing through. The paper that fused the toner image is ejected
from the face down stacker of the ejecting roller. In the case of face up ejecting, it needs to open
the backside cover and install face up stacker. (It is unavailable for duplex printing while it is face up
ejecting.)
The above is about the operations at simplex printing, yet the below explains the operations at duplex
printing. While duplex printing, the paper, which firstly passed through the fuser unit after the backside
printing, is conveyed to the inward of Duplex Unit, by the reverse operation of the second ejecting roller
that is a certain time after removing the first ejecting roller of the paper rear side. Paper, is conveyed by
conveying roller of Duplex Unit, and then merges to the same route with the feeding paper that is from
the tray. Onwards, it is the same with the simplex printing operation by the feeding paper from tray.
