Explanation

1

AUTO CLEAR

1: 10 SEC.
2: 30 SEC.
3: 60 SEC.
4: 90 SEC.
5: 120 SEC.
6: OFF

• Auto clear time automatically returns the copy settings to the initial settings if no 

keys are pressed for a preset period of time following the end of a copy job.

• This program is used to select the period of time. Auto clear time can also be 

disabled.

2

PREHEAT MODE

1: 30 SEC.
2: 1 MIN.
3: 5 MIN.
4: 30 MIN.
5: 60 MIN.
6: 120 MIN.
7: 240 MIN.

• This function automatically switches the machine to a low power consumption 

state if the set duration of time elapses without the machine being used when the 
power is on. The power save indicator lights up, however, the keys on the 
operation panel can be used. Normal operation automatically resumes when a key 
on the operation panel is pressed, an original is placed, a print job is received.

3

AUTO SHUT-OFF

1: ON
2: OFF

• Use this setting to enable or disable auto power shut-off mode.

4

AUTO SHUT-OFF 
TIME

1: 5 MIN.
2: 30 MIN.
3: 60 MIN.
4: 120 MIN.
5: 240 MIN.

• This function automatically switches the machine to a state that consumes even 

less power than preheat mode if the set duration of time elapses without the 
machine being used when the power is on. All lights except the power save 
indicator  go off. To resume normal operation, press the [START] key. Normal 
operation also resumes automatically when a print job is received or scanning is 
begun from a computer. While in auto power shut-off mode, no keys (except the 
[START] key) can be used.

5

STREAM  FEEDING

1: ON
2: OFF

• When copying using the SPF/RSPF, while "SET ORIGINALS FOR STREAM 

FEEDING." appears in the display after an original has been scanned (about 5 
seconds), a subsequent original can be placed and automatically fed into the 
machine.

6

LAYOUT IN 2IN1

1: PATTERN 1
2: PATTERN 2

• Use this setting to select the layout pattern when two original pages are copied 

onto a single sheet of paper.

7

OFFSET 
FUNCTION

1: ON
2: OFF

• When enabled, this function offsets the position in the paper output tray of sets of 

copies during copy job, and print jobs when using the printer function.

8

ROTATE ORIG. 
IMAGE

1: ON
2: OFF

• When two-sided copying is performed, this function rotates the image on the back 

of the original. This is convenient when binding the copies at the top (tablet 
binding).

9

AE/TEXT 
RESOLUTION

1: 300dpi
2: 600dpi

• This setting is used to change the copy resolution in AUTO and TEXT mode from 

600 x 300 dpi to 600 x 600 dpi (high-quality mode). Scanning is slower when high-
quality mode is used.

10

2-SIDED COPY 
MODE (AR-M155/
M155X)

1: HI-SPEED
2: NORMAL

• If the memory fills up when two-sided copying is performed, "NORMAL" can be 

selected to make copying possible. However, "NORMAL" results in a slower 
copying speed. Normally "HI-SPEED" is selected to enable fast two-sided 
copying.

11

MARGIN WIDTH

1: 5mm (1/4")
2: 10mm (1/2")
3: 15mm (3/4")
4: 20mm (1")

• Use this setting to set the margin width.

12

MEM. FOR 
PRINTER

1: 30%
2: 40%
3: 50%
4: 60%
5: 70%

• Use this to change the proportion of machine memory used for printer mode.

13

AUTO KEY REPEAT

1: ON
2: OFF

• Use this setting to select whether or not holding down a key causes repeated input 

of the key. For keys that normally cause a set value to increase when held down 
(for example, holding down the [<] key [v] or [>] key [^]), this program can be used 
to have the set value not change when the key is held down.

14

KEY PRESS TIME

1: NORMAL
2: 0.5 SEC.
3: 1.0 SEC.
4: 1.5 SEC.
5: 2.0 SEC.

• Use this setting to select how long a key must be pressed for the input to be 

accepted. By selecting a longer time, you can prevent settings from being 
changed by the accidental pressing of a key.

The machine sounds three different types of beep signals: a key
entry beep that sounds when a valid key is pressed, an invalid key
beep that sounds when an invalid key is pressed, and a base setting
beep that sounds when a setting is the same as the base setting
(base settings are explained below). The base setting beep is initially
disabled. If you wish to enable the base setting beep, see "SOUND

or disable them, see "KEY TOUCH SOUND".

The beep patterns of each type of beep signal are as follows:

Key entry beep: One beep
Invalid key beep: Two beeps

Base setting beep: Three beeps

The base settings are preset standard selections for each copy set-
ting. The base settings are as follows:
