Toner Supply
Mode Selection
† Selects the toner supply mode.
In many cases, the machine will change
the toner supply mode automatically if
either the TD or ID sensor become
unreliable. However, sometimes it does
not.
If the TD sensor fails, you can select
fixed supply mode as a temporary
measure.
If the ID sensor fails, you can select TD
sensor supply mode.
After repairing the machine, check
whether the toner supply mode has gone
back to the detect supply mode. 1: TD sensor
supply mode
