Step 4: Checking the Usage Environment of the Machine
Does the Printed Toner Flake Off Depending on Paper Type or Usage Environment?
If so, setting [Reduce Toner Flaking] to [Mode 1] may improve the problem. If that does not work, select [Mode 2].
* When this setting is enabled, ghost images may appear in unprinted areas.
Are You Using Very Dusty Paper?
Setting [Talc Paper Mode] to [On] may solve the problem.
* Specifying [On] in this setting may lead to changes in the image quality.
Are You Using the Machine in an Environment with Sudden Temperature Changes?
Sudden temperature changes can create condensation, which can result in faded or blurry images and text. Continuing to use the machine under these conditions may result in paper jams, printing defects, faults, or other problems. Allow the machine to adjust to the ambient temperature and humidity for at least 2 hours before use.
