Changing the toner control level

Description
Changes the toner feed start level set in maintenance item U130 or the
toner empty level to be determined by the difference from the toner feed
start level.

Purpose
To check the toner feed start level and toner empty level.

Method
Press the start key. The screen for selecting an item is displayed.

Setting for the toner feed start level

1

Press TARGET.

2

Change the setting using the Up/Down key.

Increasing the setting makes the toner density lower.

3

Press the print key. The value is set.

Setting for the toner empty level

1

Press EMPTY.

2

Change the setting using the Up/Down key.

Increasing the setting makes the toner empty level higher: the toner
density is lower when the toner empty is detected.

3

Press the print key. The value is set.

Completion
Press the stop/clear key. The screen for selecting maintenance item No. is
displayed.
