Toner Supply Modes
Three toner supply modes
Detect mode: Uses the ID sensor
Two fixed supply modes (3% and 6%): A fixed
amount is supplied every page, based on either
3% or 6% black coverage
The machine cannot automatically switch
between detect and fixed supply mode.
Slide 183
The main points are on the slide.
The most important point to note is that the machine cannot automatically switch
modes when the sensor breaks, or when a new one is installed.
SC400 to 406 will occur if the ID sensor fails. This is a D type code, so
copying will still be possible after the machine is switched off/on. However,
copy quality will deteriorate because no ID sensor check will be done, and
the machine will not switch itself to fixed supply mode automatically.
If the ID sensor cannot be replaced immediately, the technician has to
change to a fixed supply mode using SP 2208 003.
See the SP table for instructions on which setting to use.
SP 2207: Forced toner supply. For every execution, toner is supplied one time.
There is no ID sensor check during forced toner supply, so after doing this SP,
make a copy and check the copy density.
SP 2208 002: This can be adjusted to increase or decrease the amount of toner
supplied. Refer to the SP table in the service manual for how to use this SP.
