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
Are You Using Rough Paper?
If you are using paper with a rough surface, printed images may appear faint, particularly where the images use two or more toner colors overlaid. If so, specifying [On] for the paper source may improve the print results.
[Home] screen on the operation panel [Menu] [Adjustment/Maintenance] [Adjust Image Quality] [Special Processing] [Special Paper Processing]  [Rough Surface Paper Mode]  [On]
* Specifying [On] in this setting may lead to slower print speeds or changes in the image quality.

Step 2: Checking the Toner Cartridges

Check the Remaining Amount of Toner in the Toner Cartridges.
Check the remaining amount of toner in the toner cartridges, and replace any toner cartridges, as needed.
Checking the Remaining Amount of Consumables
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: Adjusting the Print Quality

Try Correcting Print Fading.
Setting [Prevent Print Fading/Misalign.] to [On] may improve the problem.
[Home] screen on the operation panel [Menu] [Adjustment/Maintenance] [Adjust Image Quality] [Special Processing] [Prevent Print Fading/Misalign.] [On]
* When you select [On], the printing speed may decrease.

Step 4: 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. Setting [Control Condensation] to [On] may solve the problem.
[Home] on the operation panel [Menu] [Adjustment/Maintenance] [Maintenance] [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 Auto Shutdown Time setting is disabled.
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]  [Print Side Priority]
* When you select [Print Side Priority], the printing speed for 1-Sided printing will decrease.

Step 5: Checking Whether Uneven Gloss Occur at the Edges of Printed Paper

Does Uneven Gloss Occur at the Edges of Printed Paper?
Setting [Correct Uneven Gloss] to [On] may solve the problem.
[Home] screen on the operation panel [Menu] [Adjustment/Maintenance] [Adjust Image Quality] [Special Processing] [Correct Uneven Gloss] [On]
* When you select [On], the printouts may be faded.
