Attractive Printing or Cutting is Impossible…

FAQ

The Media Becomes Soiled When Printed

Does the print head contact the media?

The height of the print head 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.

 P. 107, "Adjusting Head Height to Match Media Thickness," p. 151, "Media Feed is Not Smooth"

Is the print head dirty?

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

 Buildup of brous dust (lint) around the heads.

 Ink transferred to the heads due to rubbing against the media.

If this happens, clean the print head manually. We recommend carrying out periodic head cleaning.

 P. 75, “Maintenance that Should Be Performed More Than Once a Month”

 Tow Low Humidity.

Use this machine in the environment of 35 to 80 %RH (non condensation).

Are the pinch rollers or the media clamps dirty?

Periodically clean them.

 P. 72, "Cleaning"

Cutting Is Misaligned or Skewed

Is the media loaded and set up correctly?

If the media is not loaded and set up correctly, or media feed is not smooth, cutting may be adversely aected.

Make sure the media is loaded and set up correctly.

 P. 151, "Media Feed is Not Smooth"

Are the settings for the cutting conditions appropriate?

Misalignment or skewing may occur if the cutting speed is too fast or the blade force is too high. Try chang-

ing the cutting conditions. With media having a strong adhesive layer, the adhesive layer reattaches to itself

immediately after cutting. However, if a cutting test shows that the peeling of the media and the blade traces

on the backing paper are optimal, then the media is being cut properly. Be careful not to make the blade

force too high.

 P. 114, “Fully Utilizing Cutting Function”

Is the length of output too long?

For printing followed immediately by cutting in particular, the longer the page length (that is, the longer the

distance the media is returned after printing), the greater is the chance of misalignment occurring. It is a good

idea to keep the size of each single page to the minimum necessary.
