chart. Repeat procedures 2) to 5) until the condition ((a)-
(b)=

±1mm or less) is satisfied.

1) Lift the rear side of the machine and the angle adjustment

plate, and fix it with the screw. 

1)

Go to SIM53-6.

2)

Set the tray document guide to the max. width position, and
press [EXECUTE] key. The button is highlighted and the tray
size volume maximum value adjustment is started.
* During the adjustment, "EXECUTING..." is displayed.
* After completion of the tray size volume maximum value

adjustment, the set value is saved to EEPROM and RAM
and the display is shifted to the tray volume A4R size adjust-
ment value start screen. (Each set value is saved to
EEPROM and RAM at each setting.)

3)

Set the tray document guide to A4R (11 x 8.5R) width position
and press [EXECUTE] button. The pressed button is high-
lighted and the tray A4R size adjustment is started.

4)

Adjust the tray volume A5R (8.5 x 5 1/2R) size and the tray
size volume minimum value according to the above proce-
dures.

5)

After completion of the adjustment, "COMPLETE" is displayed.
If the adjustment is not completed normally for any rea-
son,"ERROR"is displayed. In that case, the adjustment must
be executed again.

When one of 1-4 in the above table is selected, the guide plate is
shifted to each position of the four widths of the guide plate shown
in the table below. The value of the document width sensor
(RSPF_WIDTH) A/D value is saved to EEPROM.

4) Select one of the cassettes that can be used to print SPF

adjustment patterns.

5) Press the [EXECUTE] button, and the machine starts self-print

of SPF adjustment patterns.
* The screen shows a message indicating that the machine is

self-printing SPF adjustment patterns.
When self-print finishes, the next screen appears where you
can start SPF adjustments.

6) SPF adjustment patterns are loaded into the SPF.

* By pressing the [REPRINT] button, you can return to the

cassette selection screen and have the machine self-print
SPF adjustment patterns again.

7) Press the [EXECUTE] button, and the machine starts reading

SPF adjustment patterns (for the front side).
* The screen shows a message indicating that the machine is

reading and calculating SPF adjustment patterns (for the
front side).
The machine starts calculating the adjustment amount (for
the front side) after it has read the patterns for the front side.
After the machine has finished calculating the adjustment
amount for the front side, the next screen appears where
you can have the machine start reading SPF adjustment
patterns (for the back side).

the back side) after it has read the patterns for the back side.
After the machine has finished calculating the adjustment
amount for the back side, the next screen appears where
you can view the results of the adjustments.

• SPF original leading edge adjustment (back side)
• SPF original off-center adjustment (back side)
• SPF original sub-scan magnification adjustment (back side)

10) The adjustment result screen appears.

This screen shows the current values along with the previous
values in parentheses.
* By pressing the [REPRINT] button, you can return to the

cassette selection screen and have the machine self-print
SPF adjustment patterns (for the front and back sides)
again.

* To have the machine start re-reading the SPF adjustment

patterns (front and back sides), press the [RESCAN] button.

* To return to the top menu without saving the adjustment val-

ues into EEPROM and RAM, press the [RETRY] button.
