Solution
Are you using appropriate paper?
- Check the supported paper types and replace with an appropriate type. Also, set the paper size and type correctly. For details on the procedures for loading paper, see the "User's Guide" from the Canon website (canon.com/oip-manual).
Do you print data without margins?
- This symptom occurs if a margin is set to none in the printer driver. A margin of 5 mm or less around the edge of paper or 10 mm or less around the edge of envelopes is not printable with the machine. Make sure to have margins around the document to print.

Do smudges appear when using the machine in an environment with low humidity?
- Change the setting for <Low Humidity Mode>. The improvement effect is stronger with <Mode 2> than <Mode 1>. First try with <Mode 1>. For details on the procedure for setting, see the "User's Guide" from the Canon website (canon.com/oip-manual).
NOTE
- If <Low Humidity Mode> is specified, print density may be lower or uneven when the machine is used in an environment with high humidity.
Do smudges appear on printouts depending on the paper type or the operating environment?
- Change the setting of <Correct Blurry Image>. The improvement effect is weakest with <Mode 1> and strongest with <Mode 4>. Try the adjustment starting with <Mode 1>. For details on the procedure for setting, see the "User's Guide" from the Canon website (canon.com/oip-manual).
NOTE
- Setting a stronger improvement effect may result in lighter print density or slower printing speed. It may also result in less sharp edges and rougher details.
- If [Barcode Adjustment Mode] in the printer driver is specified, the <Correct Blurry Image> setting is disabled.
Is the machine installed in an environment where the temperature changes rapidly and drastically?
- When the temperature changes rapidly in the environment where the machine is installed, condensation occurs, which may cause fading or bleeding in images and text. If <Control Condensation> is set to <On>, condensation inside the machine will be removed. Condensation removal may be performed automatically due to temperature change. For details on the procedure for setting, see the "User's Guide" from the Canon website (canon.com/oip-manual).
IMPORTANT
- While condensation removal is being performed, printing may not be performed properly and blank paper may be output.
- If you set to <On>, you need to keep the machine turned ON to maintain the effect of condensation removal.
NOTE
- The setting for <Auto Shutdown Time> is unavailable when <Control Condensation> is set to <On>.
