1.1 Specification
• Auto two-sided original feeding system
• When two-sided originals are loaded, the originals are automatically turned over
to copy both sides according to the copy mode selected at the copier.
• Function to count originals
• In auto two-sided copy mode, if the counted number of originals is an odd number,
the first copy will be a one-sided copy then the subsequent copies will be two-
sided.
• Original size feeding system
• Originals of different size but with the same width (Ledger/Letter, A3/A4) can
be combined for feeding.
• Realization of space saving
• Power unit is installed in the copier, so the former bump is removed.
• Capable of feeding originals up to Ledger/A3 size.

2. Sequence
2.1 Original paper feed system
(1) The original is transported from the original feed tray to the original
registration roller.
1) When the wait/stopper solenoid is ON and the stopper and weight have
lowered, movement of the originals from the original feed tray becomes
possible.
2) After the original feed motor stops for 50msec (300msec to 1st paper) it starts
to rotate normally and transfers the original in the direction of the registration
roller.
3) The original arrives at the registration sensor within 2200msec for the JAM
timer (1) , when the pulse count reaches 100, the original feed motor stops.
(If the original is not detected by the registration sensor within 2200msec, a
paper jam will be indicated.)
4) After the original feed motor stops for 50msec, it starts to rotate in reverse
moving the original in the direction of the platen glass.
5) When the original feed motor reaches a predetermined count, it stops and
lead edge of the original is stopped approximately 42mm into the registration
roller.
