2925 Transfer Current Timing DFU
These SP's adjust the transfer current timing.
Notes:
ƒ These adjustments can be done for each type of paper (plain, translucent,
film) as well as for the feed source (roll or cassette).
ƒ There are four voltages applied. The level of each voltage is set with
SP2301.
Transfer Current Timing Table
In the illustration above:
A
This is where voltage at the first level (SP2301-1) switches on before the leading
edge (LE) of the paper.
B
This is where the voltage switches on the second voltage level (SP2301-2) at the
leading edge of the paper.
C
This is where the voltage switches on the third voltage level (SP2301-3). This
voltage is applied to the image area (IA) between the leading and trailing edges of
the paper. Initially set at "0" this timing setting provides fine adjustments for the
type of paper.
D
This is where the voltage switches on the fourth and last voltage level (SP2301-4)
at the trailing edge (TE).
E
This is point where voltage is switched off.
