Leading Edge And Paper Size Detection - Ricoh J012 Service Manual

6.8.3

LEADING EDGE AND PAPER SIZE DETECTION

There is no paper size sensor in the standard paper cassette or in the optional 500-Sheet
Paper Tray. The paper size can be set on the printer operation panel. The paper size can
also be selected with the software application or the printer driver.
The paper size (and other settings) in the software application always have priority
over the printer driver settings.
The 1st registration sensor [1] is mounted on the carriage unit [2] and moves from side to
side with the carriage during printing.
The 1st registration sensor detects the leading edge of the sheet [3] for feed timing.
The 1st registration sensor also detects the width of the paper when it passes over and
detects the left vertical edge of the paper. This ensures that the paper below is wide
enough for the maximum printing area specified by the paper size selection for the print
job.
