Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
194 words
A method of printing, which comprises: (a) providing an ink jet droplet emitter on a scanning carriage; (b) providing a record surface positioned such that when said ink jet droplet emitter emits droplets, it prints on said record surface along a predetermined line of printing; (c) causing said ink jet droplet emitter to scan said record surface in a direction parallel to said predetermined line in a first direction; (d) causing said ink jet droplet emitter to scan said record surface in a second direction parallel to but opposite in direction from said first direction; (e) causing said ink jet droplet emitter to emit droplets while said ink jet droplet emitter is scanning in said first direction and in said second direction; (f) providing a dryer for directing a drying gas positioned on both sides of said ink jet droplet emitter on said scanning carriage such that said dryer is positioned to dry droplets on said record surface in the vicinity of said droplet emitter by directing drying gas to said vicinity on both sides of said ink jet emitter; and (g) operating said dryer to dry ink jet droplets on said record surface.
Claim 2
Independent Claim

A method of printing, which comprises: (a) providing an ink jet droplet emitter on a scanning carriage; (b) providing a record surface positioned such that when said ink jet droplet emitter emits droplets, it prints on said record surface along a predetermined line of printing; (c) causing said ink jet droplet emitter to scan said record surface in a direction parallel to said predetermined line in a first direction; (d) causing said ink jet droplet emitter to scan said record surface in a second direction parallel to but opposite in direction from said first direction; (e) causing said ink jet droplet emitter to emit droplets while said ink jet droplet emitter is scanning in said first direction and in said second direction; (f) providing a dryer for directing a drying gas positioned on both sides of said ink jet droplet emitter on said scanning carriage such that said dryer is positioned to dry droplets on said record surface in the vicinity of said droplet emitter by directing drying gas to said vicinity on both sides of said ink jet emitter; and (g) operating said dryer to dry ink jet droplets on said record surface.
Claim 3
Dependent Claim
15 words
