[12] USER PROGRAM
The user settings consist of the following items.
1. User programs
A. Copy mode
Program
numberProgram nameSetting codes
(factory default setting 
appears in bold)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 
TIME1: 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.
5STREAM FEEDING
1: ON
2: OFF•When copying using the ADF/RADF, 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.
6LAYOUT 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 
FUNCTION1: 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. 
IMAGE1: 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 
RESOLUTION1: 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 (e-STUDIO
162D/151D)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 
PRINTER1: 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 [^]), 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
AT DEFAULT. If you wish to change the volume of the beep signals
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 beepsBase setting beep: Three beeps

2. Circuit descriptions
A. Main PWB (MCU)
(1) General
The MCU PWB is composed of: 
•CPU peripheral section which performs mechanical sequence
control, U/I, and each function job management.
The CPU connects with the ASIC and memory by use of the system
bus and performs jog management and sequence control of the
whole engine.
•Image process ASIC which performs image process, CCD control,
LSU control, and print control.
•OA982 peripheral section which performs E-Sort and FAX control.
The OA982 performs image data input/output with the ASIC,
SDRAM memory management, and communication with USB2.0
devices.
•I/F section for USB2.0 and IEEE1284 control. (For the AL series,
IEEE1284 is not available.)
•Motor control circuit
•Mechanical load, sensor I/O circuit
It performs control and management of the process, the transport
loads, the fusing, the optical, and the operation panel sections for exe-
cuting a series of copy/print/scan operations.

(3) Image process ASIC (HG73C114HF)
a. General
The ASIC is composed of the three blocks: the image process block,
the print control block, and the I/F block.
Image process section
According to the operation mode set by the register set value, the
image data from the CCD PWB are placed under shading, AE pro-
cess, input gamma process, area separation, filter process, resolu-
tion conversion, zoom process, output gamma process, and binary
coding. 
Print control section
During copying, image-processed data are outputted to the LSU at
the timing of LSU writing.
I/F section
This section performs DRUM control as image data buffer, image
data send/receive with the OA982, and data send/receive with the
IEEE1284 I/F. 106 ESPAGE Input E-sort control
