Paper Feed and Transport Control

• A paper take-up and feed sequence starts if there are no preceding sheet of paper or if
the leading edge of the preceding paper has moved past the tray 2 vertical transport
roller.
• When a predetermined period of time elapses after a sheet of paper blocks the paper
feed sensor, the LCT transport roller is brought to a halt to suspend the transportation of
the sheet that was fed. After the leading edge of the preceding paper passes by the tim-
ing roller and an enough paper interval is ensured, the halt of the LCT transport roller is
released.
If there is no preceding paper or if the leading edge of the immediately preceding paper
has already passed by the timing roller by the time when the engine receives a print
request, the above-mentioned halt does not occur.
• The paper transport speed is faster than the system speed.
