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. If the problem persists, replace the toner cartridge.

Step 3: 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 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 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.
