If there is a problem with the quality of printing, first check the condition of the machine.

Possible Cause | Solution
--- | ---
There is a problem with the machine's location. | Make sure that the machine is on a level surface. Place the machine where it will not be subject to vibration or shock.
Unsupported types of paper is used. | Make sure that the paper being used is supported by the machine. See Supported Paper for Each Tray.
The paper type setting is incorrect. | Make sure that the paper type setting of the printer driver matches the type of paper loaded. See Specifying Paper Type and Paper Size.
A non-genuine print cartridge is being used. | Refilled or non-genuine print cartridge reduces print quality and can cause malfunctions. Use genuine print cartridge only. See Consumables.
An old print cartridge is being used. | Print cartridge should be opened before their expiration date and used within six months of being opened.
The machine is dirty. | See Cleaning, and clean the machine as required.
Humidity level surrounding the machine may be too low. | Using the machine in a room where humidity level is too low may cause black lines of a few millimeters thick appearing on printouts with 75-millimeter spaces in between. Selecting [On] for [Low Humidity Mode] under system settings may help to prevent these lines from appearing. See System Settings.
