maintenance soft switch functions and supply instructions for accessing them.
ACCESSING THE MAINTENANCE MODE
1. In normal operation mode without a document inserted, press
“FUNCTION l2 8 6 4” in the following sequence.
A. Press “FUNCTION” then immediately press “*“.
B. The unit will beep 3 times.
C. Immediately following the 3 beeps, press ’ 2 8 6 4 “.
NOTE: Numbers must be pressed in rapid succession.
2. The unit will emit one long beep and the LCD will display
“MAINTENANCE”, indicating it is in maintenance mode.
If the LCD does not display ‘MAINTENANCE”, press “STOP”, wait for
the LCD to display the date and time, then try step 1 again. Call
Epson Product Support at 213-539-9955 if assistance is required.
3. There are 2 levels of soft switch functions accessible in the
maintenance mode. Table 1 lists the initial level functions. Tables 2,
3, and 4 list the second level functions. The tables are located at the
end of this document.
4. To activate one of the functions listed in Tab 1, enter the initial
maintenance mode. Enter the two digit ‘Switch Number” with the keys
on the control panel. The unit will perform the function and return to
the initial maintenance mode.
The functions marked ‘NOT USED’ are either not available or require
Specialized equipment. They should only be accessed by an
authorized Epson Customer Care Center.

5. Pressing the “STOP” key in the initial maintenance mode returns the
unit to normal operation.
Pressing the “STOP” key when only one digit has been entered returns
the unit to the initial maintenance mode.
The unit returns to the initial maintenance mode when the number
entered does not correspond to a function listed in Table 1.
EEPROM PARAMETER INITIALlZATION
Function

to the factory default settings.
Operation Method
1. To activate the EEPROM Parameter Initialization, enter the initial
maintenance mode. Press the “0” key one time and then press the “1”
key one time. The LCD will display “PARAMETER INIT”.
2. Upon completion of the EEPROM Parameter Initialization, the unit Will
emit one long beep indicating it has returned to the initial maintenance
mode.
EEPROM WHITE LEVEL DATA INITIALIZATION
Function
The unit spans a blank white sheet of paper to establish a white level
reference point that is used for comparison of black and white levels.
Operation Method
1.
2.
3.
To activate the EEPROM White Level Data Initialization, enter the initial
maintenance mode. Load a blank white sheet of paper in the
document slot.
Press the “0” key one time and then press the “2” key one time. The
LCD will display “WHITE LEVEL INIT”.
Upon completion of the EEPROM white Level Data Initialization, the unit

SECOND LEVEL SOFT SWITCH FUNCTIONS
1. To 8nt8r the Second b/81 Soft Switch Functions, 8nt8r the initial
maintenance mode. Press the ‘1” k8y one time and then press the “0”
key one time. When the unit is set to the factory default settings, the
LCD will display %/SW1 =,oooooooo”.
Each “0” is r8ferred to as a
‘Switch” and they are numbered from left to right 1 through 8. Table
2 lists the function of 8aCh WSWl switch.
2. The cursor, which is the line under the first 0 on the LCD, can be
moved under any of the 8 characters that need to be changed by
using ttl8 “R” or “** key.
3. To Change a function place the cursor under the switch that needs to
be changed and press either the “1” or “0” key as necessary.

Pressing the “Next” key will store the values of WSWl in the EEPROM
and make “WSW2” available for change. When the unit is set to the
factory default settings, the LCD will display “WSW2= 113DOOOO”. Table
3 lists the function of 8aCh WSW2 switch.
In this mode, every time the “NEW key is pressed, the Current switch
settings are finalized and the next switch bank, WSWl, WSW2 or
WSW3, in that order, is made available. Table 4 lists the function of
each WSW3 switch.
If the “SF key is pressed, the current switch bank settings are saved.
The unit then emits one long beep indicating that it has returned to the
initial maintenance mode.
When the “STOP” key is preSSed, any changes made are canceled.
Th8 Unit then emits one long b88p indicating that it has r8tUtTI t0 the
initial maintenance mode.
SECOND LEVEL SOFT SWITCH FUNCTION DESCRIPTIONS
Tab18 2 Switch 1: Overseas communication mod8 (reception)
Setting switch 1 to a “1” allows the unit to acknowledge the 1100 Hz
signal that suppresses echoes, instead of a 2100 Hz which disables the
echo suppressor (ES). Suppressing th8 8Cho8S provides a more
reliable method of establishing communications.
Table 2 Switches 2 & 3: Overseas communication mod8 (Transmission)
When switch 2 is set to ‘1” and 3 is set to “O”, the unit ignores the
DIS signal sent from the calling station for suppressing echoes. Note:
Some called models may cause an error by receiving an echoed DIS.
When both switches 2 and 3 are set to “l”, the unit transmits an 1100
Hz signal for 3 Seconds upon detection of the DIS V.21 flag. This
operation prevents the called station from receiving its own DIS and
enables a no- canier state until th8 unit transmits a subsequ8ntial DIS.
Table 2 Switch 4: Direct connection mod8
When this 8witoh is set to 1, the unit starts receiving signals from the
remat station when th8 “START” k8y is pressed, r8gardl8S8 of whether
the hand set is on - hook or off - hook.
This mode is used for Cross
testing 2 fax machines when they are connected directly to 8aCh other.

Table 3 - Switches 1 - 4: Start/End Transmission speed in G3 mode
The starting and ending transmission speed can be set separately in
G3 overseas communication mode. If there is excessive noise,
decrease the starting Speed.
Increase the ending Sp88d if th8
transmission of the document takes too long. These settings are
independent of the overseas communications mode (Table 2 switches 2
and 3).
Table 4
- Switches 3 & 4: Modem Equalizer
These switches are uSed for setting the Modem Equalizer to
compensate for line loss.
m8 function section of Table 4 lists the
relationship between the line loss and the appropriate switch setting
that compensates for that loss.
Table 4
- Switches 5- 8: Modem Attenuator
These switches are used to adjust the transmission level attenuation.
The amount of attenuation is accumulative when setting more than one
switch to “1”.
For example, if switches 5 and 6 are set to “1” and
switches 7 and 8 are set to “O”, the accumulative attenuation is 12 dB.
m8 maximum attenuation with all the switches set to “1’ is 15 dB.
When a switch in this section of table 4 is set to ‘0” that switch value
is 0 dB.
SECOND LEVEL SOFT SWITCH DATA PRINTOUT
Operation Method
1. To print the “SYSTEM CONFIGUBATION LIST” which contains the
Second Level Soft Switch Data, 8nt8r th8 initial maintenance mode.
Press the “1” key twice.
Th8 LCD will continue to display
“MAINTENANCE” and the ‘SYSTEM CONFIGURATION LlSP will be
printed.
2. Upon completion of printing the “SYSTEM CONFIGURATION UST’, the
unit will emit one long beep indicating it has rstumed to the initial
maintenance mode.

Operation method
1. To activate the LCD Function Test, enter the initial maintenance mode.
Set the “Ring Delay” switch to the “4” position.
2. Press the “1” key one time and then press the “2” key one time. The
LCD will display an oblique pattern (see Figure 2).
3. Confirm that the LCD changes from the oblique, to the all black, and
then the all white pattern every time the “START’ key is pressed.
4. set the “Ring Delay” switch to the “1” position. m8 unit will emit one
long beep indicating it has returned to th8 initial maintenance mode.

functions correctly.
Operation Method
1. To activate the TAD RAM CHECK, enter the initial maintenance mode.
Press the “1” key one time and then press the “3” key one time. The
LCD will display “TAD RAM CHECK”.
2. Upon completion of the test, the unit will emit one long beep indicating
it has returned to the initial maintenance mode.
3. If an error is detected during the TAD RAM check, the unit will emit a
beep and the LCD will display “TAD RAM ERROR”.
4. Press the “STOP” key while the LCD is displaying ‘TAD RAM ERROR”,
the unit will emit one long beep indicating it has returned to the initial
maintenance mode.
