My prints show banding – Whats the cause?
Banding can come in many forms, horizontal (direction of print head), vertical (direction of paper travel), micro, etc. In general, bands are a result of the printing mechanics failing to place the ink on the paper evenly. The type of bands you are seeing will give you clues as to what part of the mechanical printing process is failing. Horizontal banding can indicate a print head alignment problem. To cure this run the print head alignment procedure as indicated in the printer manual. It may also be due to a blocked nozzle. Try a print head clean from the printer driver. Vertical banding may be caused by the printer performance and by the environmental conditions. Banding may be indicative of too low humidity. To correct this, the humidity needs to be raised so that it falls within the media manufacture’s specifications.
