CHAPTER 7 PICK-UP / FEEDING SYSTEM
I. OPERATIONS
A. Outline
The copier’s pickup system is equipped with the sources of paper shown in Table 7-101, and it
uses a center reference method, in which paper is moved in the center of the pickup/feeding path.
Model Construction
CLC 1100/1120/1140 Multifeeder + Cassette 1 + Cassette 2
CLC 1130/1160 Multifeeder + Cassette 1 + Cassette 2 + Cassette 3
CLC 1150/1180 Multifeeder1 + Duplexing unit1 + Cassette 1 + Cassette 2
Table 7-101 Sources of Paper
P aper fed from the multifeeder is moved to the registration roller. When the registration roller
starts to rotate, the attraction charging assembly turns on to keep the paper on the transfer drum.
The toner image on the photosensitive drum is transferred to the paper in this condition; i.e.,
paper is rotated a maximum of four times while it is on the transfer drum.
In the case of small-size paper (182 to 216 mm long in feeding direction), two sheets are kept
on the transfer sheet to speed up copying speed.
When transfer ends, the paper is moved through the separation, feeding, and fixing assemblies
and then to the copy tray.
Figure 7-101 is a diagram of the copier’s paper path.
The CLC

that it does not have the cassette 3. Refer to the construction of the CLC1130 /1160 .
