Colors Are Unstable or Uneven

Did you shake the ink cartridges gently

before installing them?

Before you install a new ink cartridge, gently shake
the cartridge.

Is the media wrinkled?

If the media is wrinkled and comes loose from the
platen, colors may be uneven or printing quality
may suffer.



P. 156, "Media Wrinkles or Shrinks, or Feed Is Unstable"

Is the media sagging?

Performing printing using sagging roll media makes
uneven colors more likely.

Was printing paused partway through?

When printing is paused, the coloring at the seam
may be altered when printing resumes. Avoid paus-
ing printing. With the factory-default settings, print-
ing pauses when an ink cartridge runs empty. Before
you perform lengthy printing, check the amount of
ink remaining in the ink cartridges. Printing may
also pause when data is not sent from the computer
quickly enough.

Are the operating parameters set to appro-

priate values?

Depending on the settings for such menu items as
[FULL WIDTH S] and [PERIODIC CL.], uneven colors
may occur. If the settings have been changed, try
restoring them to their default values.

Is the printer installed in a level and stable

location?

Never install the machine in a location where it is
tilted or where it may wobble or experience vibration.
Also, ensure that the print heads are not exposed to

wind or blown air. These factors may lead to missing
dots or reduced printing quality.

Is the printer being used in a location sub-

ject to severe changes in the operating

environment?

Large fluctuations in temperature or humidity while
printing is in progress may cause the colors to change
partway through. When you're performing printing,
use the machine in a location where temperature and
humidity are stable.

Are the settings for the [PRESET] menu item

appropriate?

If the settings selected with the [PRESET] menu item
are not suitable for the type of media, printing may
be adversely affected. Choose settings optimized to
the media you're using.

The Media Becomes Soiled When Printed

Do the print heads contact the media?

The height of the print heads may be too low. Also, if
the media is not loaded and set up correctly, it may
wrinkle or come loose and strike the heads.

ness"

Are the print heads dirty?

The following may cause ink to drip on the media
during printing.

• Buildup of fibrous dust (lint) around the

heads.

• Ink transferred to the heads due to rubbing

against the media.

If this happens, clean the heads using the clean-
ing kit. We recommend carrying out periodic head
cleaning.
