AL-2020/2035/2040/2050/2060  OPERATIONAL DESCRIPTIONS  7 - 8

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

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 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.)

AL-2020/2035/2040/2050/2060  OPERATIONAL DESCRIPTIONS  7 - 9

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)

SPF/RSPF 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.

Set duplex documents on the document tray.

Set paper on the cassette. (In the duplex mode, the manual feed
tray cannot be selected.)

The document feed roller feeds the document from the paper feed
roller to the PS roller.

• The document is exposed in the exposure section, and trans-

ported to the document exit section by the lower transport roller
and the paper exit roller.

• The document is transported to the paper exit tray. (However, it is

not discharged completely.)

• The document is stopped once, and then switchback operation is

performed. (To the back copy)

The paper is passed through the paper feed roller and the PS roller,
and the images on the front surface are transferred.

• The paper is passed through the fusing section and the lower

side of the gate section to the paper exit tray side. (However, it is
not discharged completely.)

• The paper is stopped once, and switchback operation is per-

formed. (To the back copy)

By switchback operation, the document is sent through the upper
transport roller and the PS roller to the exposure section, where the
back surface of the document is exposed.

• The document is sent to the document exit section by the lower

transport roller and the paper exit roller.

• The document is sent to the intermediate tray. (However, it is not

discharged completely.)

• The document is stopped once, and switchback operation is per-

formed.

• The document is sent through the upper transport roller and the

PS roller and the exposure section (without being exposed) to the
document exit section.

• The document is discharged to the document exit tray.

Switchback operation is performed.

• The paper is sent through the upper side of the gate section and

the duplex transport section and the PS roller, and the images on
the back surface are transferred.

• The paper is sent through the fusing section and discharged to

the paper exit tray.

The front and the back are in upside down each other.

The front and the back are not in upside down.

Shift width: 2.5cm

The offset function by the shifter is turned ON/OFF by the user pro-
gram.

According to the setting, offset operation is performed for every job.
