Troubleshoot by checking in the following order:

Step 1: Checking the Paper

Check whether the paper in the machine is usable, and replace it with appropriate paper, as needed.

Step 2: Checking the Toner Cartridge

If the remaining amount of toner in the toner cartridge is low, replace 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.

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.

other problems. Allow the machine to adjust to the ambient temperature and humidity for at least 2 hours

before use.
