4. PAPER FEED SECTION
A. Single-sided mode
1.
The paper feed motor (M301) switches to high speed [1] and the pick-up roller is pressed against the origi-
nals set to the original feed tray.
2.
The pick-up roller conveys the originals to the paper feed roller and the separation roller.
3.
The paper feed roller conveys a piece of original at the top, and the separation roller keeps the rest of the
originals from being transferred.
4.
The original is conveyed until it hits the registration roller, and the original forms a loop to correct skew [2].
5.
M301 pauses after the specified time, and the registration clutch (MC301) turns OFF to release the registra-
tion roller [3].
6.
After the specified time, M301 rotates in reverse at low speed and the registration roller nips the original [4].
7. After the specified time has elapsed from when the timing sensor (PS302) has turned ON, M301 is turned off
once [5] and starts rotating again in reverse at high speed [6] at the same time as the conveyance motor
(M302) is turned on. Then the original is conveyed to the conveyance belt of the conveyance section.
8.
After the specified time has elapsed from when PS302 has turned ON, M301 turns off [7].
9.
The rest of the originals are conveyed in the same manner.
