1.3.35 Assurance Mode Switch Setting (AMS) (Maintenance mode 88)
<Function>
When the machine does not function normally because the usage environments or operating
conditions are not usual, the assurance mode switches provide workarounds to make the machine
usable by changing the machine settings to untypical ones.
The machine incorporates six assurance mode switches (AMS01 through AMS06). These assurance
mode switches are firmware switches just as the WSWs described in Section 1.3.6.
The user is allowed to access the assurance mode switches under the guidance of service personnel
(e.g., by telephone).
The details about AMS01 through AMS06 are described on the following pages.
<Operating Procedure>
(1) Press the [8] key twice in the initial stage of the maintenance mode.
The machine displays "AMS00" on the LCD and becomes ready to accept an assurance mode
switch number.
(2) Using the numerical keys, enter one of the desired numbers from the assurance mode switch
numbers (01 through 06).
The following appears on the LCD:
Selector No. 1 Selector No. 8
AMSXX =0
0 0 0 0 0 0 0
(3) Use the [ ] or [ ] key to move the underline cursor to the selector position to be modified.
(4) Enter the desired number (0 or 1) using the [0] and [1] keys.
(5) Press the [SET] or [OK] key. This operation saves the newly entered selector values onto the
EEPROM and readies the machine for accepting an assurance mode switch number.
(6) Repeat steps (2) through (5) until the modification for the desired assurance mode switches is
completed.
(7) Press the [Stop] or the [X] key to return the machine to the initial stage of the maintenance
mode.
Note • To cancel this operation and return to the initial stage of the maintenance mode during the
above procedure, press the [Stop] or the [X] key.
• If there is a pause of more than one minute after a single-digit number is entered for
double-digit assurance mode switch numbers, the machine automatically returns to the
initial stage of the maintenance mode.
• Initializing the EEPROM with Maintenance code 01 or 91 initializes the assurance mode
switch settings.
