3573 Target Poten:Vd 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.
3574 Target Poten:Vl 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..
