2-3. Paper Feed
The paper taken up by the paper take-up section is fed to the transfer section after registration compensation.
(1) Registration Compensation
To eliminate any paper slant (skew), registration compensation is made by controlling the rotating timing of the paper
take-up roller and synchronizing roller.
The taken up paper passes the synchronizing roller sensor (PC2) and reaches the synchronizing roller.
At this moment, the printer delays turning timing of the synchronizing roller for a moment. As a result, the leading edge of
the paper is aligned with the stopping synchronizing roller, eliminating any skew. The leading edge of the paper will slack
a little as shown in the figure. Next, the synchronizing clutch (CL1) is activated for feeding the paper to the inside of the
printer. At the same time, the paper take-up roller turns for a moment to securely feed the paper.
(2) Paper Feeding
When the synchronizing clutch (CL1) is activated, the power is transmitted to the synchronizing roller from the transport
motor (M2) as follows and the paper is fed to the transfer section.
1 The transport motor (M2) turns counterclockwise.
→
2 The idle gear turns clockwise. The synchronizing clutch (CL1)
turns ON.
→
3 The idle gear turns counterclockwise.
→
4 The synchronizing roller turns clockwise.
→
Paper is fed.
The PC drum is driven by the I/C drive motor (M1).
As the PC drum turns, the transfer roller also turns.
Accordingly, the paper fed by the synchronizing roller
is pinched by the PC drum and transfer roller for feed-
ing to the fusing section.
