2. Using the Heater Unit

2-4 What to Do If ...

The results of printing are coarse.

The results of printing may be coarse when the media is not warm enough. In particular, the edges of the media tend not

to become as warm as the center, which may result in ink drips or unevenness, depending on the printing data. If this

happens, increase the preset temperature and perform printing again. If the printing results don't improve even when you

increase the preset temperature, the ambient temperature may be too low. Be sure to perform printing in the recom-

mended operating environment.

Setting the [SCAN INTERVAL] menu item for the printer may improve printing quality. Please refer to "3-2 Additional

Menus on the Printer."

Media wrinkles when performing printing.

Depending on the type of media, it may wrinkle when performing printing after it is left on the platen for 30 minutes to

an hour with the heater temperature at 40˚C. When you are not printing continuously, remove the media or reduce the

preset temperature to 30˚C.

Media warps before performing printing.

Depending on the type of media, it may tend to warp when there is

a large difference between the ambient temperature and the heater

temperature.

If the left and right edges of the media warp . . .

Use media clamps.

If the front edge of the media warps . . .

Reduce the heater temperature or increase the ambient temperature.

It may be possible to prevent media from warping by setting the

[VACUUM POWER] menu item of the printer. Please refer to "3-2

Additional Menus on the Printer." Front edge of the media
