3. OPERATION AND TIMING
The toner density is measured by the SALT sensor as shown in Figure 3-516. When single copies are
made, measurements are taken after each copying run; during continuous copying, measurements are
taken when all copies have been made. However, if the copy count is set to ‘100’ or higher, measurements
are taken after each 100 copies have been made.
Figure 3-516
The SALT sensor measures the density of toner, and computations are made to find out whether the
current toner density is higher or lower in comparison with the ideal density. The results of computations are
used to correct the toner supply amounts for the upcoming copying operations.
