Banding - Oce Arizona T220 User Manual

Océ | Operating the Arizona T220
• If the image is too narrow then drying time will be affected. Offset the
image from the side of the table or widen the image.
• If the media is cold, drying will be affected. The heaters turn on before the
print starts to help preheat the media, but if the media has been stored in
colder environment this will be less effective.
• Ensure the ambient temperature is within the printer's operating range. If
the table is too cold (even after the ink warm up procedure) then on thinner
media or media that are good conductors of heat, the drying will be
affected. Use the plastic perforated panels to help insulate the media from
the table.
• Consider reducing the ink limits in the PosterShop profile.

Banding

3.5.5
Banding can occur in an image for a number of reasons. Typically it occurs due to
neighbouring nozzles not firing or nozzles firing with poor directionality. This will occur
if debris has been picked up from the media or table by a printhead. If this happens,
closely inspect the underside of the carriage with a flashlight and remove the debris with
a solvent-soaked foam-tipped swab. Also check the foam capping pads for any debris.
Caution: Severe banding may be caused by the blot cloth
running out. Also, DO NOT re-use a blot cloth as this may
scratch the print and could scratch the print heads as well as
cause banding.
Keeping the table surface clean and ensuring the media is clean and dust free is highly
recommended to reduce banding.

banding.
The alignment and delays of the print heads have been calibrated at the operating
temperature. If the ink has not been allowed to warm up to its operating temperature,
then the alignments will be significantly affected and may cause banding.
Recommendations to Reduce Banding
• Keep the printer clean.
• Store the media in a warm and dry environment.
• Take care when loading the blot cloth, otherwise tracking will be affected
and the cloth will not advance. A good blot is essential for reliable print
quality.
