Canon Extra/STEINBEIS.
2) When printing is finished, "A function was finished" is displayed on the computer, and the machine
returns to be ready for selection of another function.
3) In the printout, determine the Pattern No. in which streaks or lines are the least noticeable for the LF
check pattern and the Eject check pattern respectively.
(LF Pattern No. 0 to 4, Eject Pattern No. 0 to 4)
4) Select and set the correction values.
In the LF/EJECT Correction section of the Service Tool, select the Pattern No. (from 0 to 4)
determined in step 3) for LF and EJECT respectively, and click Set.
5) The selected LF and Eject correction values are written to the EEPROM, making the E-MIP correction
value (which was set at shipment from the production site) invalid.
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, but the selected values are printed after the LF / Eject
correction).

2) Easy-Scroll Wheel check
2-1) Press the OK button, then rotate the Easy-Scroll Wheel clockwise step by step. The LCD is divided
into 6 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 (6 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.
2-2) When the Easy-Scroll Wheel is rotated clockwise 1 round (6 steps), press the OK button.
2-3) Rotate the Easy-Scroll Wheel counterclockwise step by step. The LCD is divided into 6 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 (6 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.
2-4) When the Easy-Scroll Wheel is rotated counterclockwise 1 round (6steps, 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.

3) Transparent pattern display check
3-1) 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."
Wait for approx. 2 seconds.
3-2) 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."
4) LCD flicker adjustment
4-1) Press the OK button. The LCD flicker adjustment screen is displayed.
4-2) By pressing the left or right cursor button, change the VrefPWM value to eliminate flicker on the
screen. The specifiable VrefPWM values are from 36 to 3D (hexadecimal).
4-3) Press the OK button. The machine returns to be ready for selection of another function ("Service
Mode Idle" is displayed on the LCD).
(5) Ink absorber counter setting
Set the ink absorber counter value to a new EEPROM after the logic board is replaced in servicing.
1) Before replacement of the logic board, check the ink absorber counter value in EEPROM information
print.
2) After replacement of the logic board, the ink absorber counter value should be set in the service mode
using the Service Tool.
In the Ink Absorber Counter section of the Service Tool, select Main from the Absorber pull-down
menu.
From the Counter Value(%) pull-down menu, select the value (in 10% increments) which is the closest
to the actual counter value confirmed before replacement of the logic board, and click Set.
3) Print EEPROM information to confirm that the value is properly set to the EEPROM.

4-4. Special Notes on Servicing
(1) Print head problem (smeared printing, uneven printing, non-ejection of ink, etc.)
For problems that are supposed to be caused by the print head (smeared printing, uneven printing, or nonejection of ink, etc.), print the nozzle check pattern to determine whether the print head is faulty or not.
< Procedures >
0) Using the tool print head, confirm that the test printer (to be used to examine the print head in question)
operates properly, then install the print head in question in that test printer.
1) Print the nozzle check pattern (in the user mode or in the service mode).
2) If there is a missing portion in the printed pattern, perform the print head cleaning (2 times at the
maximum), and print the nozzle check pattern again.
3) If the problem persists even after the print head cleaning is performed 2 times, perform the print head
deep cleaning, then print the nozzle check pattern again.
4) If the problem is still not resolved, i) turn off the machine and leave it for 24 hours or longer, ii) perform
the print head cleaning, and iii) print the nozzle check pattern again.
5) If the problem still persists after steps 1) to 4), the print head may be faulty. Replace the print head.
(2) Paper feed motor adjustment
1) When attaching the motor, fasten the screws so that the belt is properly stretched (in the direction
indicated by the blue arrow in the photo below).
2) After replacement, be sure to perform the service test print, and confirm that no strange noise or faulty
print operation (due to dislocation of the belt or gear, or out-of-phase motor, etc.) occurs.
The screws securing the paper feed motor may be loosened only at replacement of the
paper feed motor unit. DO NOT loosen them in other cases.
57 / 64
(3) Carriage unit replacement
To replace the carriage, the carriage rail must be removed from the main chassis (by removing the screws).
Before removing the screws, put a mark on the main chassis to indicate the carriage rail position.
After replacing the carriage, return the carriage rail to the original position while aligning the rail to the
mark on the chassis.
(4) Document pressure sheet (sponge sheet) replacement
1) Peel off the cover sheet from the double-sided adhesive tape on the back of the document pressure sheet.
With the long-side down, position the upper-left corner of the document pressure sheet at the scanning
reference point on the platen glass (back left where the red lines cross in the photo above).
2) Slowly close the document pressure plate while maintaining the hinge position. The document pressure
sheet will attach to the plate frame.
3) Open the plate to confirm the following:
- No extension of the sponge edges over the mold part of the upper scanner cover.
- No gap between the platen glass reference edges and the corresponding sponge edges.
- No shades or streaks in monochrome test printing without a document on the platen glass.
(5) Ink absorber counter setting
Before replacement of the logic board, check the ink absorber counter value, and register it to the replaced
new logic board. (The value can be set in 10% increments.)
In addition, according to the ink absorber counter value, replace the ink absorber (ink absorber kit). When
the ink absorber is replaced, reset the applicable ink absorber counter (to 0%).
- How to check the ink absorber value and the way to set the ink absorber counter:
See 4-2. Service Mode.

5. MACHINE TRANSPORTATION
This section describes the procedures for transporting the machine for returning after repair, etc.
1) In the service mode, press the ON 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 by pressing the ON button to securely lock the carriage in the home position.
(When the machine is turned off, the carriage is automatically locked in place. DO NOT disconnect the
power cord until the carriage is completely 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. Make sure that the carriage is locked in place at power-off.
- 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).
