The cassette set sensor [F] detects paper after the paper cassette is pulled out or is not correctly locked in
its position.
Paper Cassette Pre-Feeding
Paper does not pre-feed from the cassette before the copy job starts. The machine pre-feeds paper from
the cassette only between pages of multi-page copy jobs.
There are two pre-feed positions for the leading edge of cut sheets after the first sheet of a multi-page copy
job. The length of the paper in the cassette controls the pre-feed position.
• Pre-feed position 1 [A] is 234.8 mm below the RF exit sensor [B]. This is for cut sheets 18.7 inches
(457.2 mm) long. (This is the maximum length for the paper cassette.)
• Pre-feed position 2 [C] is 184.4 mm below the RF exit sensor. This is for cut sheets less than 18.7
inches long.
Position 1 (lower than Position 2) is used for longer paper. This prevents overlap between the leading edge
of a sheet and the trailing edge of the sheet before it.
