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>.
●
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>.
<Correct Blurry Image>(P. 482)
●
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.
<Control Condensation>(P. 484)
●
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.
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>.
<Correct Blurry Image for Copy>(P. 483)
●
Setting a stronger improvement effect may result in lighter print density.
