Note
•
If the cutter is damaged, contact your Canon dealer for assistance.

About the Printhead
• If the printhead rubs against the paper during printing, this may cause damage to the printhead. If the printhead is
rubbing against the paper, configure the
Vacuum Strength in the Step 5: Configure the amount of ink used
dialog box as follows.
• For paper-based media such as Heavyweight Coated Paper: Set to Strong or Strongest
• For film-based media such as CAD Tracing Paper: Set to Standard , Strong , or Strongest
• For thin paper of thickness 0.1mm or less: Set to Weakest
Note
•
If the printhead still rubs even after changing the Vacuum Strength , set the Head Height to be higher in the Step 5: Config-
ure the amount of ink used dialog box.
•
For details on how to handle the printhead rubbing against the paper, see "Paper rubs against the printhead."

About Borderless Printing
•
When performing borderless printing on paper where the ink does not dry well, the cutter unit may leave scratches
where it touches the printed surface, or may not cut correctly. In this kind of situation, configure the amount of time
to wait for the ink to dry after printing using
Drying Time in the Roll Paper Settings dialog box.
Alternatively, if the paper cannot be cut well by the cutter, set the Automatic Cutting Settings to User Cut in the
Roll Paper Settings dialog box, and cut the roll paper using scissors, etc.
About the Print Quality
•
If the edges of images are blurry, set the Vacuum Strength to be weaker in the Step 5: Configure the amount of
ink used dialog box.
• If lines are warped or scratched, set the Head Height to be lower in the Step 5: Configure the amount of ink
used dialog box.
• If the amount of ink used is too much, wrinkles may appear and the ink may bleed in the printed material. Further-
more, if the amount of ink used is too little, color production may be poor and lines may become scratched. In this
kind of situation, change the amount of ink used in the
Step 5: Configure the amount of ink used dialog box.
• If horizontal bands with different color tone appear in the printed material, execute Paper Feed Adjustment in the
Step 4: Paper feed adjustment dialog box. If you have already executed Paper Feed Adjustment , execute Adj.
Fine Feed from the printer control panel and fine tune the amount of paper feed.
Note
•
For details on Adj. Fine Feed ,
see "Fine-Tuning the Paper Feed Amount."
→P.807
•
If horizontal bands appear even after executing Adj. Fine Feed , refer to "Banding in different colors occurs" in "Trouble-
shooting". (See "Banding in different colors occurs.")
→P.990
• If printed sheets are affected by banding in different colors toward the end of the sheet (about 20–30 mm from the
edge), try adjusting the feed amount of the trailing edge of sheets.
(See "Adjusting Color on the Trailing Edge of
Sheets.")
→P.809
• If you cannot obtain sufficiently high print quality, change the maximum ink usage, or change the media type used
as the basis for the custom paper in the
Step 1: Select the standard paper dialog box.
• If there is no luster in printed material, set the paper used as the basis for the custom paper to a paper that uses
photo ink as the Black ink.
The types of Black ink used are displayed on the right side of each media type in the
Step 1: Select the standard
paper dialog box.
