(3) LF / Eject correction
After replacement of the feed roller, platen unit, LF / Eject encoder, carriage encoder film, or logic board in repair
servicing or in refurbishment operation, perform the adjustment to maintain the optimal print image quality.
If the print quality is considered unaffected by replacement of those parts, it is not necessary to perform LF / Eject
correction.
1) Print the LF / Eject correction pattern.
Click LF/EJECT of the Service Tool, select the paper source and the paper type, and print the pattern. 5 sheets
of A4 paper will be used for the pattern printing.
- Paper source: Select either Rear tray or Cassette.
- Media type: Select one from HR-101, GF-500/Office Planner, HP Bright White, and Canon
Extra/STEINBEIS.
2) When printing is finished, the machine returns to be ready for selection of another function ( " A function was
finished " is displayed on the screen).
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).

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 Scroll Wheel is rotated clockwise 1 round (6 steps), press the OK button.
2-3) Rotate the 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.
48 / 62
2-4) When the Scroll Wheel is rotated counterclockwise 1 round (6 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.
2-5) Press the ON button to turn off the machine.

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.
(6) Disc label print position correction
Set the disc label print position value to a new EEPROM after the logic board is replaced in servicing.
This function can be also used in solving user complaints in the field, however, use of the application software is
recommended for solution of user complaints.
1) Before replacement of the logic board, check the disc label print position value in EEPROM information print.
2) After replacement of the logic board, set the disc label print position value in the service mode using the
Service Tool, CD-R Correction section.
3) If the disc label print position value from the original logic board is not available due to the logic board failure,
etc., print the CD-R check pattern and confirm that the intersection of the X axis and Y axis is at the center of
a printable disc.

(1) For smeared printing, uneven printing, or non-ejection of ink
When smeared printing, uneven printing, or non-ejection of ink occurs, print the nozzle check pattern to determine
whether the print head is faulty or not.
& lt; Procedures & gt;
1) Examine the ink tank conditions.
- Is the outer film completely removed to open the air-through?
- Re-install the ink tanks.
- Is the ink tank Canon-genuine or not?
- Is the ink tank refilled one or not?
2) Remove and clean any foreign material from the caps of the purge unit.
3) Perform print head cleaning or deep cleaning.
4) Perform print head alignment.
5) Print the nozzle check pattern.
6) If the nozzle check pattern is not printed properly, the print head may be faulty. Perform troubleshooting
while referring to the Print Head Workshop Manual or the Print Head Service Manual, 1-4. Troubleshooting.

(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.
52 / 62
(3) Carriage unit replacement
In the MG5100 series, the carriage rail needs to be removed from the main chassis.
Before removing the screws from the carriage rail, 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.

6. 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 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 pigmentbased 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).
