Warnings
Take note of the following warnings when added custom paper other than Canon genuine paper and feed confirmed
paper to the printer driver and the printer itself.
About the Cutter
Depending on the paper, there are types that cannot be cut by the cutter unit, and types that speed deterioration
•
of the blade and cause damage to the cutter. For thick paper, hard paper, etc. do not use the cutter unit, and in-
stead cut the roll paper using scissors, etc. after printing. In this case, select User Cut as the Automatic Cutting
Settings in the Roll Paper Settings dialog box.
• If the cutter is damaged, contact your Canon dealer for assistance.
Note • For details on the methods for cutting roll paper, see "Specifying the Cutting Method for Rolls."
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
•
• 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.
Note
• 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.
• For details on Adj. Fine Feed, see "Fine-Tuning the Paper Feed Amount."
618
• If horizontal bands appear even after executing Adj. Fine Feed, refer to "Banding in different colors occurs" in "Trouble-
Note
shooting". (See "Banding in different colors occurs.")
