Toner Supply Control Modes
This machine uses 5 toner supply modes. The mode used
depends on SP3-044-001 to –004.
These are the five modes:
PID control mode
PID control mode with fixed VT
Fixed supply mode
MBD control mode: This is the default mode.
MBD control mode with fixed VT
You can select a different mode for each color, if
necessary.
Use SP 3-044 if the TD sensor and/or ID sensor breaks and
no spare part is available.
After replacing the part, return the SP setting to the default.
