service modes.

*2: Alarm code created by UGW (it is not recorded in the LUI log). Since this alarm is generated only once per bottle, it will no
longer be generated for the same bottle once this alarm has been generated.
*3: The message can be hidden by configuring the setting in the following service mode. This message is hidden when prior
delivery is performed.
• COPIER > OPTION > DSPLY-SW > TNR-WARN
*4: The condition for displaying the message can be changed in the range from 0 to 40 % by configuring the setting in the following
service mode (Level 2).
• COPIER > OPTION > DSPLY-SW > T-LW-LVL
*5: The toner supply count is the amount of toner supplied from the Toner Container to the Developing Assembly.
CAUTION:
The message to inform of the absence of toner may be displayed before the message to warn of the remaining toner level
if the value of (Lv.2) COPIER>OPTION>DSPLY-SW>T-LW-LVL is lowered than the initial value due to the margin of the
toner supply count.
