Printing Is Uneven

Troubleshoot by checking in the following order:

Step 1: Checking the Paper

Are You Using Appropriate Paper?
Check whether the paper in the machine is usable, and replace it with appropriate paper, as needed.
Usable Paper
Loading Paper

Step 2: Checking the Toner Cartridge

Check the Remaining Amount of Toner in the Toner Cartridge.
If the remaining amount of toner in the toner cartridge is low, replace the toner cartridge.
Checking the Remaining Amount of Consumables
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.
[Home] screen on the operation panel  [Menu]    [Adjustment/Maintenance]    [Adjust Image Quality]    [Special Processing]    [High Humidity Mode]    [On]  
* 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.
[Home] on the operation panel [Menu]    [Function Settings]    [Common]    [Paper Feed Settings]    [Switch Paper Feed Method]    [Drawer 1]  [Print Side Priority]  
* When you select [Print Side Priority], the printing speed for 1-Sided printing will decrease.
