C600D104.WMF
The DF has one width sensor [A] to detect the original width and two original length
sensors (-1 [B] and -2 [C]) to detect the original length. The DF detects the original
size through the combination of inputs from those sensors as shown in the table on
the next page.
When using an original of a non-standard size, the user needs to input the original
length at the operation panel.
The original width sensor [A] has four possible outputs (P1 to P4). The output
depends on the position of the sliding electrode on the original rear fence.
During one-to-one copying, copy paper is fed to the registration roller in advance,
to increase the copy speed. The original exit trailing edge sensor monitors the
stack of originals in the feeder, and detects when the trailing edge of the last page
has been fed in.
