1.3.35 Assurance Mode Switch Setting (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 seven assurance mode switches (AMS01 through AMS07)
that are firmware switches just as the ones described in Section 1.3.6 in this chapter.
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 AMS07 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) Enter the desired number from the assurance mode switch numbers (01 through
07).
The following appears on the LCD:
Selector 1 Selector 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 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 X key to return the machine to the initial stage of the maintenance mode.
Notes• To cancel this operation and return the machine to the initial stage of the
maintenance mode during the above procedure, press 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 will
automatically return to the initial stage of the maintenance mode.
• Initializing the EEPROM with Maintenance mode 01 or 91 initializes the AMS
switch settings.
