Toner Supply Determination
The reference voltage (either Vts or Vref) is the
threshold voltage for determining whether or not
to supply toner.
If Vt becomes greater than the reference voltage,
the machine supplies additional toner.
This can be checked using SP 2220.
» SP2220 displays both Vt and Vref
» Vt > Vref = toner is supplied.
(See the next slide for toner supply motor on times.)
