good.
Paper Size Sensing Problem
(The printed area does not fit on the page, or the paper size cannot
be changed from the operator panel.)
Make sure the paper tray and its stops are undamaged. Make sure
the cable to the paper size switch is connected correctly. With the
paper tray removed, the resistance of the paper size switch should
be infinite. With the tray installed, the resistance of the switch varies
with the paper size.
For Tray 1, remove the front cover, disconnect the cable from the
sensor and measure the resistance between the two pins on the
sensor board.
For 500-Sheet Option or 200-Sheet Second Drawer, Non-Rt,
remove the RIP Board, disconnect J15 from the engine board, and
measure between J15-3 and J15-4 on the cable.
For 200-Sheet Tray 2, Rt, remove the RIP board, disconnect J17
from the engine board, and measure between J17-3 and J17-4 on
the cable.
If the readings do not match the following within 5% replace the
paper size sensor.
