<LF / Eject correction>

After replacement of the feed roller, logic board, or platen unit in repair servicing or in refurbishment operation, perform the adjustment to maintain the optimal print image quality.

Details: Print the LF / Eject correction pattern on a sheet of paper. Select the Pattern No. (0 to 2) in which streaks or lines are the least noticeable, press the Stop/Reset button the same number of time(s) as the selected Pattern No., then press the ON/OFF button. (See the flowchart below.)

Note: At the production site, the E-MIP correction, which is equivalent to the LF / Eject correction, is performed using the special tool, and the E-MIP correction value is written to the EEPROM as the valid data.

When LF / Eject correction is performed, the LF / Eject correction values become valid instead of the E-MIP correction value (thus, in the initial EEPROM information print, "LF = *" and "EJ = *" are printed).

1) In the LF / Eject correction mode, press the Stop/Reset button the specified number of time(s) according to the paper to be used in

LF / Eject correction listed in the table below, then press the ON/OFF button. (Set a sheet of selected paper in the rear tray.)

<Button and LCD test>

Confirm the operation after replacement of the operation panel unit, board, or LCD unit.

1) In the button and LCD test mode, press the Stop/Reset button. The LCD turns blue, waiting for a button to be pressed.

2) Press each button of the operation panel.

3) Only one button should be pressed at one time. If 2 or more buttons are pressed at the same time, only one of them is considered to be pressed, and the other buttons are ignored.

The LCD is divided into 25 segments, representing each button. The color of a segment corresponding to the pressed button changes to red.

After all the 17 buttons are pressed, the remaining segments (from 18 to 25) turn red at the same time.

4) Rotate the Easy-Scroll Wheel clockwise and counterclockwise 1 round (24 steps) each, as follows:

4-1) Rotate the Easy-Scroll Wheel clockwise step by step. The LCD is divided into 24 segments, representing each step. The color of a segment corresponding to the step changes from red to green.

If the wheel is rotated counterclockwise before clockwise round completes, the color of segment(s) corresponding to the number of steps the wheel is rotated counterclockwise returns to red.

If the wheel keeps rotated clockwise over 1 round (24 steps), the color of segment(s) corresponding to the extra number of steps returns to red, starting with the "Start" segment in the figure below.

4-2) When the Easy-Scroll Wheel is rotated clockwise 1 round (24 steps), press the OK button.

4-3) Rotate the Easy-Scroll Wheel counterclockwise step by step. The LCD is divided into 24 segments, representing each step. The color of a segment corresponding to the step changes from green to blue.

If the wheel is rotated clockwise before counterclockwise round completes, the color of segment(s) corresponding to the number of steps the wheel is rotated clockwise returns to green.

If the wheel keeps rotated counterclockwise over 1 round (24 steps), the color of segment(s) corresponding to the extra number of steps returns to green, starting with the "Start" segment in the figure below.

4-4) When the Easy-Scroll Wheel is rotated counterclockwise 1 round (24 steps, and all the segments are in blue), press the OK button. The color pattern is displayed on the LCD.

If there is any segment that is not in blue when the OK button is pressed, the display remains unchanged.

5) Adjust the transparent color and LCD flicker, as follows:

5-1) Press the OK button. "OK1" in white is displayed on the black background.

If the result is not good, "NG1" in black is displayed on the white background (transparent color) immediately after "OK1."

5-2) Press the OK button. "OK2" in black is displayed on the white background.

If the result is not good, "NG2" in white is displayed on the black background (transparent color) immediately after "OK2."

5-3) Press the OK button. The machine enters the LCD flicker adjustment mode. (See the flowchart below.)

5-4) Press the ON/OFF button to return to the service mode menu selection.

4. MACHINE TRANSPORTATION

TABLE OF CONTENTS

This section describes the procedures for transporting the machine for returning after repair, etc.

1) In the service mode, press the ON/OFF button to finish the mode, and confirm that the paper lifting plate of the rear tray is raised.

2) Keep the print head and ink tanks installed in the carriage.

See Caution 1 below.

3) Turn off the machine to securely lock the carriage in the home position. (When the machine is turned off, the carriage is automatically locked in place.)

See Caution 2 below.

(1) If the print head is removed from the machine and left alone by itself, ink (the pigment-based black ink in particular) is likely to dry. For this reason, keep the print head installed in the machine even during transportation.

(2) Securely lock the carriage in the home position, to prevent the carriage from moving and applying stress to the carriage flexible cable, or causing ink leakage, during transportation.

If the print head must be removed from the machine and transported alone, attach the protective cap (used when the packing was opened) to the print head (to protect the print head face from damage due to shocks).
