Normally this adjustment is performed with SIM 46-2 and SIM 46-3. In
this method, two or more copy density adjustments in different modes
can be adjusted collectively.

1) Execute SIM 46-2 and SIM 46-3.

This adjustment is used when a different density level for different
copy quality mode is required. SIM 46-5 to -7 and SIM 46-9 to -11 are
used.

1) Execute the simulation corresponding to the copy quality mode to

be adjusted.

2) Press the COPY button to make a copy.

Check that the copy density is as shown in the table below. If not,
change the adjustment value.

For the auto mode, there is only one adjustment value. For the
other modes, the adjustment value for each density level must be
adjusted.

Make a copy of the chart in the AE exposure OC mode.

Make a copy of the chart in the RSPF mode.

Compare the above two copies to check that the difference is within
0.5 scale. If the difference is more than 0.5 scale, adjust with SIM
46-20.

When the RSPF is darker, increase the value.
When the RSPF is lighter, decrease the value.

1) Execute SIM 40-2.

2) Extend the manual paper feed guide fully.

3) Press [MAX POSITION] on the LCD of the operation panel to

highlight it.

4) Press [EXECUTE] on the LCD of the operation panel to highlight

it.

If normal, the highlight is shifted from [MAX POSITION] to [MIN
POSITION].

5) Narrow the manual paper feed tray guide fully.

6) Press [EXECUTE] on the LCD of the operation panel to highlight

it.

Check that [COMPLETE] is highlighted.

7) Press the CA key to cancel the simulation.

When the center of No. 1 and No. 2 paper feed trays is shifted with
the reference of manual paper feed and the self print, adjust as
follows.

1) Loosen the fixing screws a and b of the front cabinet of the paper

feed tray.

*

When fixing the front cabinet, the clearance between fixing
screw a and the cabinet and the clearance between fixing
screw b and the cabinet are symmetric.

[Reference view]

2) Shift the front cabinet and adjust.

Move the front cabinet in the direction of A.

Move the front cabinet in the direction of B.

This adjustment is to adjust the time from when the resist roller is
turned on to when the drum separation pawl is turned on.

1) Execute SIM 51-1.

2) Change value A and adjust the separation pawl operating timing.

Initial value:

This adjustment is to adjust the timing (paper contact pressure) for
the resist roller in each paper feed mode.

By changing the time difference (timing) between the transport roller
ON and the resist roller ON, the paper contact pressure on the resist
roller is changed.

The adjustment value must be changed according to the copy paper
quality.

1) Execute SIM 51-2.

2) Change the adjustment value in each mode.

When the set value is too small, the copy image position for the
paper may vary.

*

When the set value is too great, a paper jam may occur.

1) Execute SIM 41-2.

(Fig. 1)

2) Execute the sensor adjustment without original.

With the original cover open, without original on the table glass,
press the [EXECUTE] key to perform the sensor adjustment with-
out original. After adjustment, NORMAL or ABNORMAL is dis-
played.

(Fig. 2)

(Fig. 3)

(In the case of NORMAL)

The screen of Fig. 2 is displayed for 1 sec, then the screen of Fig.
3 is displayed, and the sensor adjustment without original is com-
pleted.

(Fig. 4)

(In the case of ABNORMAL)

The screen of Fig. 4 is displayed, and the sensor of abnormality is
highlighted. In this case, confirm the original empty state and
press the [EXECUTE] key to perform the sensor adjustment
again. 3) Perform the sensor adjustment without original.

3) Execute the sensor adjustment with original.

With the original cover open, place five sheets of A3 originals on
the glass by fitting them to the original guide, press the [EXE-
CUTE] key to perform the sensor adjustment with originals. After
adjustment, NORMAL or ABNORMAL is displayed.

(In the case of NORMAL)

The screen of Fig. 2 is displayed for 1 sec, then the screen of Fig.
3 is displayed to terminate the adjustment of the original sensor.

*

In this case, the display item of "2. A3 ORIGINAL" is shown
instead of "1. NO ORIGINAL" at the left top.

(In the case of ABNORMAL)

The screen of Fig. 4 is displayed for 1 sec, and the sensor of
abnormality is highlighted. In this case, check that there is no A3
original on the original glass, and press the [EXECUTE] key to
perform the sensor adjustment operation again.

*

In this case, the display item of "2. A3 ORIGINAL" is shown
instead of "1. NO ORIGINAL" at the left top.

1) Execute SIM 41-1.

·

Slowly tilt the original detecting arm unit, and loosen the origi-
nal cover switch actuator adjustment screw, and slide and ad-
just the actuator so that the highlighted display of OCSW is
changed to the normal display when the height of the arm unit
top from the table glass is  32 

±

 0.5 mm.

(When the original cover switch ON timing is shifted, the origi-
nal detection function may not work properly.)

1) Fill water to the empty waste toner bottles to make dummy bottle

A and B.

Dummy bottle A:  480g (including the bottle weight)

Dummy bottle B:  560g (including the bottle weight)

2) Turn on the power switch of the copier.

3) Install dummy bottle A (480g) to the waste toner bottle detecting

unit and check that the weight detection is OFF.

4) Install dummy bottle B (500g) instead and check that the weight

detection is ON.

"Weight detection ON" means that the display of "REPLACE
TONER BOTTLE" on the panel display is ON. "Weight detection
OFF" means that it is OFF.

Initial value:

2 scales down from the center

Loosen the fixing screw of the positioning plate. Move the positioning
plate up and down to adjust so that the weight detection is made as
specified.
