Print Quality Problems

Checking the Condition of the Machine

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 page 35 "Supported Paper".

The paper type setting is incorrect.

Make sure that the paper type setting of the printer driver

matches the type of paper loaded. See page 35 "Supported

Paper".

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 page 251 "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 page 201 "Maintaining the Machine", 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 to appear on

printouts with 75-millimeter spaces in between. In this case, set

[Low Humidity Mode] to [On].

For details about how to configure the settings, see page 147

"System Settings".
