17. PAPER FEED SECTION
C. Paper feed retry control
• If the specified sensor is unable to detect the paper even after the lapse of a predeter-
mined period of time after the start of the paper feed sequence, the machine determines
that there is a paper misfeed. The paper feed sequence is, however, repeated a second
time, if a paper misfeed is detected in a print job of a specific color mode. A paper mis-
feed results if the specified sensor is still unable to detect the paper even after the paper
feed retry sequence, the machine determines that there is a paper misfeed.

D. Paper feed speed reduction control
• If the sheet of paper being controlled reaches the paper feed tray 1(2) paper feed sensor
with a smaller distance relative to the preceding sheet of paper during a multi-print cycle,
the paper feed tray 1(2) paper feed clutch is temporarily deenergized to thereby retard
the paper feed timing of the sheet of paper being controlled. The paper-to-paper distance
is thereby corrected to an appropriate value. Note, however, that the paper feed tray 1(2)
paper feed sensor is mounted on C360/C280 only and no paper feed speed reduction
control is performed for the tray 1/2 paper feed section in C220. (C220 has a lower print
speed than the higher-end models, which eliminates the need for paper feed speed
reduction control.)
