Printouts Are Faded

Troubleshoot by checking the following steps:

Step 1: Checking the Paper and Toner Cartridge

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
Set the paper size and type correctly according to the loaded paper. Specifying the Paper Size and Type
Is Printing Faded When Printing Envelopes?
When printing on envelopes with a rough surface, setting [Rough Surface Envelope Mode] to [On] may solve the problem.
[Home] screen on the control panel [Menu] [Adjustment/Maintenance] [Adjust Image Quality] [Special Processing] [Special Paper Processing] [Rough Surface Envelope Mode] [On]
* This setting is only available when the paper type is set to [Rough Surface Envelope Mode].
* Specifying [On] decreases the printing speed.
* Specifying [On] disables the [Paper Curl Correction] setting.
Have the Toner Cartridge Reached the End of Their Lifetime?
Parts inside the toner cartridge may have deteriorated. If this symptom occurs, it is recommended to replace the toner cartridge regardless of the remaining amount of toner or messages displayed. 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. If the problem persists, replace the toner cartridge.

Step 2: 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.
[Home] on the control 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 automatic shutdown 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 control 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.
