P_EDGE Sensor Adjustment
1.
Remove the rear cover’s access cover (2 screws).
2.
The self-diagnostic mode is started by turning on the Power switch while pressing the
following buttons.
n
Paper Feed – Cut / Eject Cleaning Button
Press the Paper Source button and select “Check: Test”, then press the Enter button.
3.
Press the Paper Source button and select “Test : Sensors”, then press the Enter button.
4.
Press the Paper Source button and select “Sen: Edge AD.” At that time, make sure that
the LCD displays “Sen: Edge AD ttt vvv.”
NOTE:
“ttt” or “vvv” is a hexadecimal number that changes depending on the
printer’s state.
5.
As necessary, the access cover on the paper guide should be removed.
6.
Raise the paper set lever, then set a sheet of A3 size plain copy paper (PPC paper) in
the paper path, then lower the paper set lever to fix the paper in position. At this time,
make sure the front edge of the sheet of paper is at the paper front edge setting position
on paper guide L.
7.
Move the CR unit over the paper and close the front cover halfway. At this time, if the
vvv value in the LCD display does not change, the subsequent operation can be
performed with the front cover in the open state. If the vvv value changes, use adhesive
tape, etc. to fix the front cover in the half closed state.
NOTE:
Move the CR unit over the paper so that the CR unit’s right edge is
aligned with the paper’s right edge.
8.
Confirm that the LCD displays the following.
n
LCD Display: “Sen: Edge AD ttt vvv”
n
ttt value: 040<H> or higher
n
vvv value: Should be a value between 0E0<H> and 0E8<H>
If the ttt value is lower than 040<H>, carry out the rough adjustment with the VR1
element, then carry out the fine adjustment with the VR 5 element.
If the VR1 element is set on the maximum, and vvv does not reach 0E0<H>, adjust the
VR1 element so that the sensor detection level when there is no paper rises, adjusting it
so that it reaches 0E0<H> when paper is present. If adjustment is impossible, replace
the sensor.
9.
Raise the paper set lever, then after removing the paper, return the paper set lever to the
paper set position.
