1.4.32 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
1.4.6 .
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) Enter [8] and [8] 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 the desired double-digit number 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 [ ] or [ ] to move the underline cursor to the selector position to be modified.
(4) Enter the desired number (0 or 1) using [0] and [1].
(5) Press [SET] or [OK]. 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 [Stop] or [X] 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 [Stop] or [X].
• 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.
