Maintaining Print Quality |

• 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
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.
Keeping the table surface clean and ensuring the media is clean and dust free is highly
recommended.
The alignment and delays of the print heads have been calibrated to a minimum ink
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.

Other Recommendations
• 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.
• After opening the carriage cover always check that the tubes exiting the
bottom of the ink reservoirs are clipped to the side of the ink reservoir,
otherwise the acceleration of the carriage may affect the performance of the
heads.
• Ensure that the Prefire Stripe Catcher is set to the correct height. Also make
sure that any sacrificial media or the aluminum hold down strips used for
bleed or for prefire stripes is at the same height or no more than 1mm
thinner than the media.
Note:
Using the Diagnostic Stripe helps to quickly pinpoint the cause of any
banding.
