AR-RP9/SP9/AR-D33  OPERATIONAL DESCRIPTIONS  4 - 2

1) The SPPD is ON when turning ON the power.

2) The SPPD does not turn ON for 4.0sec from starting document

feed. (in 100% copy)

3) The SPPD does not turn OFF for 4.7sec after detecting turning

ON of the SPPD. (100% copy)

4) The RSPF cover or the OC cover is opened during document

transportation.

5) The SRJD is ON when the power is turned ON.

6) The SRJD is not turned ON for 2.4sec from release of PS in

paper feed from the document set position. (100% copy)

7) The SRJD is not turned OFF for 1.6sec from completion of doc-

ument scan in the case of complete document exit. (100%
copy)

1) When SPPD is ON (document remaining) in initializing.

2) When SPPD is not turned ON within about 4.0 sec (at 100%

copy) after starting the document feed operation.

3) When SPPD is not turned OFF within about 4.7 sec (at 100%

copy) after turning on SPPD.

4) When the OC cover is opened during document transport (dur-

ing SPF motor rotation) (The SPF motor is stopped during doc-
ument transport, but the OC cover open error occurs instead of
the SPF JAM.)

RSPF/SPF open/close detection (book document) detection is per-
formed 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.

Note: When replacing the carriage unit, be sure to execute SIM41-

06.

If SIM41-06 is not executed, the carriage unit may not read
the reference line on the white Mylar, preventing the docu-
ment from being fed.
