Smudges Appear on Printouts

A possible cause may be that appropriate paper is not used or there is a problem with the operating environment. Check the following.

Are you using appropriate paper?

Check usable paper, and replace with appropriate paper.

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>.  
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>.  
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.  
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.
If you set to <On>, the setting of Auto Shutdown is disabled.  

Do smudges appear on copy job output depending on the paper type or the environmental conditions?

Changing the setting of <Correct Blurry Image for Copy> may solve the problem. The improvement effect is weakest with <Mode 1> and strongest with <Mode 3>.  
NOTE
Setting a stronger improvement effect may result in lighter print density.
