MX-B201/B201D  OPERATIONAL DESCRIPTIONS  7 - 6

1) Before paper feed operation, the manual paper feed solenoid

(MPFS) is turned OFF as shown in the figure below.

2) When the Start key is pressed, the manual paper feed solenoid

(MPFS) turns on to disengage the manual paper feed latch.
A from the manual paper feed clutch sleeve A, rotating the man-
ual paper feed roller and the manual take-up roller. At the same
time, the manual paper feed stopper opens and the manual
take-up roller is pressed to the surface of the paper to start
paper feeding.

3) When pawl C of the manual paper feed clutch sleeve is

engaged with the manual feed latch, the manual feed stopper
falls and the manual take-up roller rises. At that time, the man-
ual paper feed roller is rotating.

4) The lead edge of the transported paper is pressed on the resist

roller by the transport roller. Then the paper is stopped tempo-
rarily to allow synchronization with the lead edge of the image
on the OPC drum.
From this point, the operation is the same as the paper feed
operation from the tray. (Refer to 7-5 - 8.)

5) The solenoid turns off to close the gate and return to the initial

state.

MX-B201/B201D  OPERATIONAL DESCRIPTIONS  7 - 8

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

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)

MX-B201/B201D  OPERATIONAL DESCRIPTIONS  7 - 9

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.
