This SP displays the TD sensor target voltage. This target voltage is inversely proportional to
the density of the toner:
• If the target is high, toner density is lowered.
• If the target is low, toner density is raised.
The machine uses readings of the ID sensor patterns between pages to determine the amount
of toner coverage and compared with the threhold values for the upper and lower limit of
coverate. The result of this calculation is used to calculate Vtref.
Note: Vtref is the TD sensor reference voltage. It is frequently updated to stabilize the toner
concentration in the development unit.
