4.3.4 Registration control
Transmitting the FS start signal [1], the transfer motor (M203) rotates in low speed and the pick-up solenoids /
UP (SD201) and /Lw (SD202) turn ON. At the time, the tray lift motors /Up (M201) and /Lw (M202) rotate in the
forward direction to lift up the trays /Up and /Lw.
M201 and M202 stop when the tray upper limit sensors /Up (PS205) and /Lw (PS209) turn ON [2], and after a
specified period of time, the transfer clutch /Up (MC201) and /Lw (MC202) turn ON and the paper is picked up
from the tray. Only 1 sheet of paper is transferred by the transfer roller because of the separation roller.
M203 rotates in high speed when the paper reaches the paper passage sensors /Up (PS201) and /Lw (PS206)
[3]. At the time, the paper is pressed against the transfer roller and forms a loop because the registration clutch
(MC203) is OFF. After a specified period of time, MC203 turns ON [4] and M203 drives the paper to FS.
M203 switches to rotate in low speed to feed the subsequent paper since the paper passed PS201/PS206 [5],
and then MC203 turns OFF after a specified period of time.
