ABSTRACT:
An ink supply system for use with high speed multiple layer form collators includes a first ink supply reservoir in fluid communication with a second ink supply reservoir, and a pump to enable flow of ink from the first ink supply reservoir to the second ink supply reservoir. The second ink supply reservoir supplies ink to a print head. The second ink supply reservoir is divided into an inlet chamber into which ink from the first ink supply reservoir is received, an outlet chamber, the outlet chamber having a one or more outlets leading to print heads, and an overflow chamber. Internal partitions within the second ink supply reservoir ensure that the inlet chamber fills before overflowing into the outlet chamber and that the outlet chamber overflows into the overflow chamber. Ink settles in the inlet and outlet chambers thus allowing any turbulence to dissipate. A constant head pressure in the outlet chamber promotes constant ink flow and even print density.
