3042 Set Vtref Cor
Vtref is frequently updated in the toner supply cycle to stabiize the concentration 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 default 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.

3101 ID Pattern:Disp
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 pattern to a
hatched pattern.
Note: SP3171 001 sets detection and update timing for the creation of the ID sensor
patterns.
