Conveyance takes place as a result of the transmission of
rotational force from M151 (ADU paper feed) by means of the
CL153 (ADU timing).
M151 and CL153 are driven by the CB (control board).
Related signals are PS154 (ADU paper exit 1), PS155 (ADU
paper exit 2) and PS156 (ADU paper exit 3).
1. Operation
CL153 goes ON in synchronism with M1 (main), and
conveys the reversed paper from the stacker to the main
body paper feed unit. If the PS18 (no feed) is ON when
PS19 (optical synchronizing) is turned ON, CL153 goes
OFF for a moment until PS18 is turned OFF. When PS18
is turned OFF CL153 goes ON again and when PS14
(registration)
is turned OFF by final paper, CL153 goes
OFF.
2. Signals
a. Input signals
(1) PS154 (PS154 → CB)
“Jammed paper at entrance of ADU conveyance sec-
tion” detection signal.
This signal becomes [ L ] when paper is detected.
(2) PS155 (PS155 → CB)
“Jammed paper inside ADU conveyance section” de-
tection signal.
This signal becomes [ L ] when paper is detected.
(3) PS156 (PS156 → CB)
“Jammed paper at exit of ADU conveyance section”
detection signal.
This signal becomes [ L ] when paper is detected.
b. Output signals

(3) CL151 DRIVE (CB → CL151)
ON/OFF control signal for CL151
[H]: CL151 OFF
[L]: CL151 ON
(4) CL152 DRIVE (CB → CL152)
ON/OFF control signal for CL152
[H]: CL152 OFF
[L]: CL152 ON
