Replacing the Toner Cartridge

* 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.

Step 3: Checking the Usage Environment of the Machine

Are You Using the Machine in a Humid Environment?

Setting [High Humidity Mode] to [On] may solve the problem.

* Setting this to [On] may blur images and text in an environment with low humidity.

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.

Is the Machine Installed in a Location Subject to Strong Wind Such as from an Air Conditioner?

If so, adjust the air direction and volume of the air conditioner.
If that does not work, setting [Switch Paper Feed Method] to [Print Side Priority] may improve the problem.
