Paper Is Smudged/Printed Surface Is Scratched/Ink Blots/Paper Curl

  1. Check1 Check paper and print quality settings.

  2. Check2 Check paper type.

    Make sure you are using the right paper for what you are printing. To print data with high color saturation such as photographs or images with dark colors, we recommend that you use Photo Paper Plus Glossy II or other Canon specialty paper.

  3. Check3 Correct curl before loading paper.

    When using Photo Paper Plus Semi-gloss, even if the sheet is curled, load one sheet at a time as it is. Rolling this paper in the opposite direction to flatten it may crack the paper surface and reduce the print quality.

    We recommend putting unused paper back into the package and storing it flat.

    • Plain Paper

      Turn the paper over and reload it to print on the other side.

    • Other Paper such as envelope

      If the paper corners curl more than 0.1 in. / 3 mm (A) in height, the paper may smudge or may not feed properly. Follow the instructions below to correct the paper curl.

      1. Roll up paper in opposite direction to paper curl as shown below.

        roll up paper

      2. Check that paper is now flat.

        We recommend printing curl-corrected paper one sheet at a time.

    Note

    • Depending on paper type, the paper may smudge or may not feed properly even if it is not curled inward. Follow the instructions below to curl the paper outward up to 0.1 in. / 3 mm (C) in height before printing. This may improve the print result.

      (B) Print side

      We recommend feeding paper that has been curled outward one sheet at a time.

  4. Check4 Set printer to prevent paper abrasion.

    Adjusting the setting to prevent paper abrasion will widen the clearance between the print head and the paper. If you notice abrasion even with the media type set correctly to match the paper, set the printer to prevent paper abrasion using the operation panel or the computer.

    This may reduce the print speed.

    * Once you have finished printing, undo this setting. Otherwise, it will apply to subsequent print jobs.

    Select (Setup) on HOME screen, select Printer settings > Print settings in this order, and then set Prevent paper abrasion to ON.

    Note

    • If User management settings is enabled, the user selection screen is displayed before the HOME screen is displayed.

  5. Check5 If ink bleeds, make sure that Improve bleeding and thickened black text/lines (plain paper) is checked. (Windows)

    It may be possible to improve the bleeding of characters and lines when printing on plain paper.

    Set it at Print Options dialogbox on Page Setup sheet in the printer driver.

    Restore the setting after printing.

  6. Check6 If brightness is set low, increase brightness setting and try printing again.

    If you are printing with a low brightness setting on plain paper, the paper may absorb too much ink and become wavy, causing paper abrasion.

    • Printing from your computer (Windows)

      Check the brightness setting in the printer driver.

  7. Check7 Is platen glass dirty?

    Clean the platen glass.

  8. Check8 Is paper feed roller dirty?

    Clean paper feed roller.

    Note

    • Cleaning the paper feed roller abrades it, so do this only when necessary.

  9. Check9 Is inside of printer dirty?

    During duplex printing, ink may stain the inside of the printer, smudging the printout.

    Perform bottom plate cleaning to clean inside of printer.

    Note

    • To prevent staining inside the printer, be sure to set the correct paper size.

  10. Check10 Set longer ink drying time.

    This allows the printed surface to dry, preventing smudges and scratches.
