[3] Disassembly and Re-assembly
1. Adjusting the Original Reversal Solenoid
(SD301)
a. Procedure
(1) Remove the five set screws and remove main body
base plate (C).
(2) Remove the three set screws and remove main body
base plate (D).
(3) When original reversal solenoid (SD301) is on/off,
adjust installation position of the SD301 so that the
distance of the switching guide and conveyance roller
is within specifications.
[4] Reversal/Exit Control
Reversal/exit takes place as a result of the transmission of
the drive force of M303 (paper exit) to the paper exit roller.
Switchover between reversal and paper exit takes place as
a result of the UP/DOWN motion of the switching guide by
SD301 (reversal). M303 and SD301 are controlled by the
RADFCB (RADF control board).
1. Operation
a. Reversal operation
In the two-sided original mode, the original that is conveyed
from the conveyance section after the copy has been made
is reversed in the reversal section, and the reverse side
copied.
In the reversal section, the switching guide separates from
the paper exit roller side as a result of SD301 going ON. As
a result, the original is guided once again to the conveyance
section side.
b. Paper exit operation
The original that was conveyed from the conveyance section
is sent to the conveyance roller as a result of M303 going
ON.
In this case, SD301 is OFF, so the switching guide is at the
paper exit roller side, and the original is exited as it is.
