Replacing the Toner Cartridges

* Depending on the usage condition of the machine, the actual remaining amount of toner may be lower than indicated or the parts may be deteriorated. If the condition persists even after replacing the toner cartridge indicated to have a low amount of toner, it is recommended to replace the other toner cartridges as well.

Step 3: Checking the Occurrence of White Spots

Do White Spots Occur on the Leading Edge of the Paper?

This symptom may occur when printing on thin paper. Setting [Correct Void] to [On] may solve the problem.

[On]

* When you select [On], the printouts may be faded.

Step 4: Checking the Usage Environment of the Machine

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. Setting [Control Condensation] to [On] may solve the problem.

[Control Condensation]

[On]

* During condensation removal, a blank sheet of paper may be output without being printed correctly. If you set this to [On], you can set whether to restrict printing.
* If you set this to [On], you must keep the machine ON to continuously remove the condensation. The automatic shutdown setting is disabled.

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].

Are You Using the Machine in an Environment with Low Humidity?
