DSPF/RSPF adjustment patterns are loaded into the DSPF/
RSPF.

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

cassette selection screen and have the machine self-print
DSPF/RSPF adjustment patterns again.

7)

Press the [EXECUTE] button, and the machine starts reading
DSPF/RSPF adjustment patterns (for the front side).
* The screen shows a message indicating that the machine is

reading and calculating DSPF/RSPF 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 DSPF/RSPF adjust-
ment patterns (for the back side).

• DSPF/RSPF original leading edge adjustment (front side)
• DSPF/RSPF original off-center adjustment (front side)
• DSPF/RSPF sub-scan magnification ratio adjustment (front

side)

8)

DSPF/RSPF adjustment patterns are loaded into the DSPF/
RSPF.

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

cassette selection screen and have the machine self-print
DSPF/RSPF adjustment patterns again.

9)

Press the [EXECUTE] button, and the machine starts loading
DSPF/RSPF adjustment patterns (for the back side).
* The screen shows a message indicating that the machine is

reading DSPF/RSPF adjustment patterns (for the back
side).
The machine starts calculating the adjustment amount (for
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.

• DSPF/RSPF original leading edge adjustment (back side)
• DSPF/RSPF original off-center adjustment (back side)
• DSPF/RSPF sub-scan magnification ratio 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
DSPF/RSPF adjustment patterns (for the front and back
sides) again.

* To have the machine start re-reading the DSPF/RSPF

adjustment patterns (front and back sides), press the [RES-
CAN] button.

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

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

Normally there is no need to perform this adjustment. In the follow-
ing cases, perform this adjustment.
* When a paper jam occurs in the fusing section.
* When wrinkles are made on paper in the fusing section.
* When an image deflection or an image blur is generated in the

paper rear edge section.

1)

Loosen the fusing paper guide fixing screws which are on two
position in the front/rear frame direction.

2)

Use the fusing paper guide position scale as the reference to
shift the paper guide in the arrow direction A or B.

The standard fixing position is one scale lower than the center
of the marking scale. Change the actual fixing position accord-
ing to the condition.
* When wrinkles are generated on paper, change the position

in the arrow direction B.

* When an image deflection or an image blur is generated in

the paper rear edge section, change the position in the
arrow direction A.

check, clear.

7)

Various (adjustments, setting, operation, counters, etc.) data
transport.

The operating procedures and displays depend on the design of
the operation panel of the machine.

* Entering the simulation mode

 CLEAR key ON  Asterisk (*) key ON  Ready for input of
a main code of simulation

2)

Entering a main code with the 10-key 

 START key ON.

Or select a main code with the SIM key on the touch panel.

3)

Entering a sub code with the 10-key 

 START key ON.

4)
