2-2 Loading Media

About the Ambient Temperature During Heater Use

To ensure stable printing quality, we recommend use in an environment where the ambient temperature is 20˚C (68˚F)

or higher.

At low temperatures, warm-up may take a long time, or the temperature may fail to reach the preset value, or large

differences in temperature may occur. Inadequate temperature may result in coarse printing.

If the media fails to warm up sufficiently, try setting the heater to a higher temperature. If this fails to resolve the

problem, raise the temperature of the room.

Points to Observe When Loading Media

Check and observe the following points when loading media. For detailed information on how to load media, refer to

the user's manual for the printer.

Use Media With a Width of about 1 m (40 in.) or More

We recommend using media having a width of about 1 m (40 in.) or more. Media of narrower width may take a long

time to heat, or may fail to reach the preset temperature.

Also, in no event should media having a width of 50 cm (19-11/16 in.) or less be used. Doing so may lead to danger of

overheating.

Before Loading Media, Allow the Heater to Cool Down to 30˚C (86˚F) or Lower

Before loading media, switch off the controller or set the preset temperature to 30˚C and allow the heater to cool down.

Loading media when the heater is 30˚C (86˚F) or more may cause the media to wrinkle or warp due to the sudden rise

in temperature.

When Printing, Use the Media Clamps

Set the height of the printing heads to either "Middle" or "High," then engage the media clamps. Depending on the

media, the edges of the media may warp due to heat or the media may strike the printing heads, causing jams or

malfunction.
