1) Gently lift and pull out the paper tray until it stops.

2) Push the pressure plate down until it locks in place.

3) Squeeze the lock lever of the front guide and slide the front guide

to match the width of the paper.

4) Move the left guide to the appropriate slot as marked on the tray.

•

When using 11" 

×

17" copy paper, store the left guide in the slot

at the left front of the paper tray.

5) Load copy paper into the tray.

6) Place the paper size plate in the front of the paper tray.

•

The paper size indication which shows through the slot on the
front of the copier should match the selected paper size.

7) Push the paper tray firmly back into the copier.

8) To set the selected paper size, press and hold down the PAPER

SIZE ENTER key. The selected paper feed location indicator and
the corresponding paper size (which has been set) indicator will
blink. All other indicators will go out.

•

For paper size setting, ensure that the COPY mode has been
selected. However, if printer or facsimile output is being per-
formed, paper size setting cannot be made even in the COPY
mode.

9) Use the TRAY SELECT key to select the paper tray of which the

paper size has been changed.

•

Each time the TRAY SELECT key is pressed, a paper tray is
indicated with a blinking paper feed location indicator. If an
optional paper feed unit is not installed, this operation is not
needed.

10) Use the ORIGINAL SIZE ENTER key to select the paper size

which is set.

•

Each time the ORIGINAL SIZE ENTER key is pressed, a
paper size will be indicated with a blinking paper size in-
dicator.

11) Press the START key and then the PAPER SIZE ENTER key.

•

To change the paper size setting of another tray, repeat steps
9 to 10 after pressing the START key.

1) Loosen the developing doctor fixing screw A.

2) Insert a thickness gauge of 1.5mm to the three positions at 20mm

and 130mm from the both ends of the developing doctor as
shown. 

3) Push the developing doctor in the arrow direction, and tighten the

developing doctor fixing screw. (Perform the same procedure for
the front and the rear frames.)

4) Check the clearance of the developing doctor. If it is within the

specified range, then fix the doctor fixing screw with screw lock. 

* When inserting a thickness gauge, be careful not to scratch the

developing doctor and the MG roller.

1) Remove and separate the waste toner box and put the developing

unit on a flat surface. 

2) Tie a string to a needle or a pin. 

3) Hold the string and bring the needle close to the MG roller

horizontally. (Do not use  paper clip, which is too heavy to make a
correct adjustment.) (Put the developing unit horizontally for this
adjustment.)

4) Do not bring the needle into contact with the MG roller, but bring it

to a position 2 or 3mm apart from the MG roller. Mark the point on
the MG roller which is on the extension line from the needle tip. 

5) Measure the distance from the marking position to the top of the

doctor plate of the developing unit to insure that it is 18mm.
If the distance is not within the specified range, loosen the fixing
screw A of the main pole adjustment plate, and move the adjust-
ment plate in the arrow direction to adjust.

Note:

•

Use a digital multi-meter with an internal resistance of
10M

Ω or more.

1) Set the digital multi-meter range to DC700V. 

2) Put the test rod of the digital multi-meter on the developing bias

voltage output check pin. 

3) Turn on the power.

4) Adjust the adjustment volume VR31 so that the output voltage is

within the specified range shown below.

3) Turn on the power. 

4) Adjust the adjustment volumes (VR51, VR52) so that the output

a. OC image lead edge position adjustment
Note: In advance to this adjustment, the sub scanning magnification

ratio adjustment must be performed.

1) Set a scale on the OC table as shown below.

2) Make a copy.

3) Check the copy output. If necessary, perform the following adjust-

ment procedures.

4) Execute SIM 50-1.

5) Set the OC lead edge position set value (Exposure display

<AUTO> ON) to “99.”
The OC image scanning start position is shifted inside the docu-
ment edge.

6) Set the main cassette lead edge void adjustment value (Exposure

display <PHOTO> ON) * to “1.”
The lead edge void becomes the minimum.

7) Set the print start position value (Exposure display <EXP1> ON)

to “99” and make a copy.
The print start position is shifted inside the document edge.

8) Measure the image loss R of the copied image. Enter the set

value of the image scanning lead edge position (Exposure display
<AUTO> ON) again.

•

1 step of the set value corresponds to about 0.127mm shift.

•

Calculate the set value from the formula below.

99 - R/0.127 (mm) = Image loss set value <R: Image loss meas-
urement value (mm)>

Example: 99 - 4/0.127 = 99 - 31.5 = about 67

Note: If the set value is not obtained from the above formula,

perform the fine adjustment.
