Printed Surface Is Scratched/Paper Is Smudged

Clean the Paper Feed Roller. Cleaning the Paper Feed Roller will wear the roller, so perform this procedure only when necessary. For details on cleaning, see "Cleaning the Paper Feed Roller (Roller Cleaning) ".

When performing duplex printing, if the specified page size does not match the actual size of paper loaded in the paper source, the inside will become stained with ink, causing printed paper to become smudged.

Perform the Bottom Plate Cleaning to clean the inside of the machine.

For details on cleaning, see "Cleaning the Inside of the Machine (Bottom Plate Cleaning)".

Caution

Set the Ink Drying Wait Time longer.

Doing so gives the time enough to dry the printed surface so that paper curling and ink blots are prevented.

(1) Make sure that the machine is turned on.

(2) Open the printer properties dialog box.

(3) Click the Maintenance tab and then Custom Settings.

(4) Drag the Ink Drying Wait Time slide bar to set the wait time, and then click Send.

(5) Confirm the message and click OK.

(1) Make sure that the machine is turned on.

(2) Open the Canon IJ Printer Utility.

(3) Select Custom Settings in the pop-up menu.

(4) Drag the Ink Drying Wait Time slide bar to set the wait time, and then click Send.

(5) Confirm the message and click OK.

If you are using paper with either any of the corners or the whole printing surface curled, the paper may become dirty, not feed properly, or both. Use such paper after correcting paper curl as follows.

(1) With the printing side (A) facing up, cover the paper with a fresh sheet of plain paper to avoid staining or scratching the surface.

(2) Roll up the paper in a direction opposite to paper curl as seen below.

(3) Check to see that the paper curl is within approximately 0.08 to 0.2 inches / 2 to 5 mm (B) in height.

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

Caution

Selecting the Prevent paper abrasion setting will widen the clearance between the Print Head and the loaded paper. If you notice abrasion even with the media type set correctly to match the loaded paper, set the machine to prevent paper abrasion by using the Operation Panel on the machine or the printer driver.*

* Deactivate the Prevent paper abrasion setting once printing is complete. If not, this setting remains enabled for all subsequent print jobs.

From the HOME screen, select Settings, Device settings, and Print settings in this order, and then set Prevent paper abrasion to ON.

Open the printer properties dialog box, and in Custom Settings in the Maintenance sheet, select the Prevent paper abrasion check box, and then click Send.

In the Canon IJ Printer Utility, select Custom Settings in the pop-up menu, select the Prevent paper abrasion check box, and then click Send.

Especially if you are using plain paper to print images with high intensity, the paper may absorb too much ink and become wavy, causing paper abrasion.

Reduce the Intensity setting in the printer driver and try printing again.

(1) Open the printer properties dialog box.

(2) On the Main sheet, select Manual for Color/Intensity, and then click Set.

(3) Drag the Intensity slide bar to adjust the intensity.

(1) Open the Print dialog box.

(2) Select Color Options in the pop-up menu.

(3) Drag the Intensity slide bar to set the intensity.

See "Copying" and reduce the Intensity setting. Then try printing again.

If you are printing beyond the recommended printing area of your printing paper, the lower edge of the paper may become stained with ink.

Resize your original document in your application software.
