Set Vtref Cor Set Vtref Correction
Vtref is frequently updated in the toner supply cycle to stabiize the concent ration of
toner in the developer. Vtref is corrected between every printed page in the paper
path using the correction amounts listed below for each color. This is the defa ult
setting (0) for SP3042 001. However, you can use this SP to switch this function
OFF.
Vtref (TD sensor reference voltage). It is frequently updated to stabilize the toner
concentration in the development unit.

ID Pattern:Disp ID Sensor Pattern Coverage Display
Displays the amount toner to be used (coverage) to create the ID sensor patterns
between pages. The ID sensors cannot accurately detect the patterns if there is too
much reflectivity from the black toner. This SP changes the solid ID sensor patt e r n to
a hatched pattern.
Note: SP3171 001 sets detection and update timing for the creation of the ID sensor
patterns.
