INK RECYCLING IN A TEXTILE PRINTER

Abstract:

A method of recycling ink used in non-printing nozzle dispensing operations in an ink jet printer, comprises collecting the ink from the non-printing operation in a collection tray, draining the ink from the collection tray into a closed cell, draining the ink from the closed cell, filtering the ink draining from the closed cell, and adding the ink back to a main ink supply after filtering, the main ink supply containing fresh ink. To maintain the quality of the ink supply the proportion of recycled to fresh ink may be limited to a maximum.
