Display Target Potential (VdDisplay)
Vd (read by the potential sensor) is the potential of dark areas of a drum before full laser
exposure. This SP displays the value of Vd used by processing control to determine the target
potential (Vd). The machine performs a calculation using development gamma, Vk and the
maximum coverage, and then uses the result to lookup and retrieve the correct voltage from
the Potential Table. This retrieved value is used to raise the charge of the charge roller that
charges the drums.

Display Target Potential (VlDisplay)
Vl (read by the potential sensor) is the potential of the exposed areas after full laser exposure.
This SP displays the value of Vl used by processing control to determine the target potential
(Vl). The machine performs a calculation using development gamma, Vk and the maximum
coverage, and then uses the result to lookup and retrieve the correct voltage from the Potential
Table. This retrieved value is used to raise the input current of the laser diode.
