Caution in handling of medias

Pay attention to the followings for handling of medias.

• When handling media, wear the gloves.

If you touch the media with your bare hand, the media may be stained due to fingerprints or oil of your finger. Be careful about it.

•Do not leave the media with the heater ON for a long time. Waviness may occur on the media and it may cause media clogging.

When the pinch roller is at the lower position, even if it is for a short time, impression produced by the pinch roller is left depending on the media material. Perform test feeding (P.2-19)to check the media status.

•Use media recommended by RIOCH to ensure reliable, high-quality printing. Set the heater temperature to meet the characteristics of the media.

•Set the temperature of the Pre-heater, Print heater and Post-heater according to the type and characteristics of the media used.

Automatic temperature setting can be made on the operation panel by setting the profile on the dedicated RIP. For setting on the RIP, refer to the instruction manual for your RIP.

•Pay attention to the expansion and contraction of the media.

Do not use media immediately after unpacking. The media can be affected by the room temperature and humidity, and thus it may expand and contract.

The media have to be left in the atmosphere in which they are to be used for 30 minutes or more after unpacked.

•Do not use curled media.

This may result in paper jamming.

If a regular-sized coated sheet of media is rolled and stored, the coated side has to face outside.

•Be careful to dusts on the edge face of the medium.

Some rolls have dusts contained in the package gathered on the edge surface of the roll. If you use as it is, the drawing quality may be degraded due to nozzle missing or ink drops. Be sure to set the roll after removing dusts adhering on the edge face of the roll.

•Use a media wider than 450 mm when performing the ink drop position correction for bidirectional printing. Correcting the ink drop position for bidirectional printing cannot be performed on narrower media. Use unidirectional printing in such a case. Also, select [STRONG] in the [VACUUM] setting if the media is not securely adhered to the media transfer surface when using a media such as narrow media.
