4 Multifeeder Paper Width Sensor
Adjustment
In this adjustment, you will be storing the char-
acteristics of the multifeeder paper width sensor
using service mode No. 501.
Perform the adjustment if you have replaced the
sensor or if the machine wrongly identifies paper
sizes.
1) Open the front door, and insert the door switch
actuator into the door switch.
2) Press the service mode switch (SW850) with a
hex key.
• The machine starts service mode and indi-
cates ‘1’.
3) Press ‘5’ on the numeric keypad.
• The display indicates ‘5’.
4) Press the AE key.
• The machine starts machine settings mode
and indicates ‘501’.
5) Press the Start key.
• The display indicates ‘A3’.
6) Select the appropriate paper size (except CLR).
(A press on the numeric keypad brings out a list
shown in Table 3-802.)
• If you select a size not stored, the display will
start to flash.
• If you press the Start key when ‘CLR’ is
indicated, all stored settings will be cleared
and returned to default settings.
7) Adjust the guide of the multifeeder to suit the
size you are setting.
• Make sure you feel a click when positioning
the guide.
8) Press the AE key.
• When the setting has been stored, the display
stops flashing and remains ON.
9) Press the Reset key.
• The machine ends service mode.

Reference:
1. If you are storing the size under No. 9 (JPC),
adjust the guides so that they are closest.
2. At time of shipment from the factory, A3,
A4R and JPC (North America model: 11×17,
LGL and Sr) are pre-stored, and the char-
acteristic curves of these three sizes are
computed and the results are used for
identification of paper sizes. If you enter a
size other than these three in the field, the
machine will compute a characteristic curve
with the addition of the data obtained from
the new size. For this reason, it is best to
store the sizes of the papers the user tends
to use frequently.
