AR-168N/168L OPERATIONAL DESCRIPTIONS 7 - 7
(3) Conditions of occurrence of paper misfeed
a. When the power is turned on:
PPD or POD is ON when the power is turned on.
b. Copy operation
6. RSPF section
A. Outline
The RSPF (Reverse Single Path Feeder) is installed to the AR-168L
as a standard provision, and it automatically copies up to 30 sheets of
documents of a same size. (Only one set of copies)
B. Document transport path and basic composition
(RSPF)
C. Operational descriptions
D. Cases where a document jam is caused
1) When SPPD is ON (document remaining) when the power is
turned on.
2) When SPPD is not turned ON within about 1.5 sec (at 100% copy)
after starting the document feed operation.
3) When SPPD is not turned on within about 4.7 sec (at 100% copy)
after turning on SPPD.
4) When the RSPF document jam release door or the OC cover is
opened during document transport (RSPF motor rotating).
E. RSPF open/close detection (book document
detection)
RSPF open/close detection (book document) detection is performed
by detecting the interval between the reference lines on the white
Mylar attached to the paper exit guide (document scanning section) by
the scanner (CCD) and detecting the varied quantity.
a
PPD1 jam
PPD1 does not turn off within 4 sec after turning
on the resist roller.
b
PPD2 jam
PPD2 is off immediately after turning on the
resist roller.
PPD2 does not turn off within 1.2 sec after
turning off the resist roller.
c
POD jam
POD does not turn on within 2.9 sec after turning
on the resist roller.
POD does not turn off within 1.5 sec - 2.7 sec
after turning off PPD2.

(Exposure)
In the zooming mode, the magnification ratio in the sub

by changing the document transport speed.
