METHOD AND APPARATUS FOR DISPENSING MATERIAL IN A PRINTER
First Claim
1. A printer for printing a viscous material at predetermined positions forming a pattern on a substrate, the printer comprising:
- a frame;
a device, mounted to the frame, having a number of perforations arranged to form the pattern;
a support apparatus, coupled to the frame, that supports the substrate in a printing position beneath the device; and
a material dispenser having a chamber to contain the viscous material to be printed on the substrate, the chamber having an opening through which the viscous material is dispensed, the material dispenser being coupled to the frame, positioned over the device, and constructed and arranged to dispense the viscous material through the perforations in the device and onto the substrate, the material dispenser having a retraction device that prevents leakage of the viscous material from the opening after dispensing is complete.

Abstract
A printer for printing a viscous material at predetermined positions forming a pattern on a substrate. The printer includes a frame, a device, mounted to the frame, having a number of perforations arranged to form the pattern, a support apparatus, coupled to the frame, that supports the substrate in a printing position beneath the device, and a material dispenser. The material dispenser has a chamber to contain the viscous material to be printed on the substrate. The chamber has an opening through which the viscous material is dispensed. The material dispenser is coupled to the frame, positioned over the device, and constructed and arranged to dispense the viscous material through the perforations in the device and onto the substrate. The material dispenser has a retraction device that prevents leakage of the viscous material from the opening after dispensing is complete.

18. A method for printing a pattern of viscous material on a substrate using a dispenser having a chamber with an inlet to receive viscous material and an outlet from which viscous material is dispensed, the chamber having a volume, the method comprising steps of:
-
positioning the dispenser over the substrate;
applying pressure to the viscous material in the chamber to dispense viscous material from the outlet of the chamber onto the substrate;
relieving the pressure applied to the viscous material to discontinue dispensing; and
expanding the volume of the chamber to retain the viscous material in the chamber. - View Dependent Claims (19, 20, 21)
