1.2 Super Fine Interlace Processing (720dpi) This is a method to perform printing using nozzles moved at 4/360 inch pitch using nozzles spaced at 2/360 inch pitch. Fig. 2.2 below shows the relationship between the printing area and the line feed amount for each head print pass. pass2 pass3 pass4 pass5 pass6 pass7 pass8 pass1 (Position to start to printing) pass2 pass3 pass4 pass5 pass6 pass7 pass8 pass1 pass2 Area covered by the printing head Interlace table 1 Interlace table 2 Interlace table 3 Interlace table 4 Interlace table 5 Interlace table 6 Interlace table 7 Interlace table 8 Interlace table 1 Interlace table 2 Interlace table 3 Interlace table 4 Interlace table 5 Interlace table 6 Interlace table 7 Interlace table 8 (Line feed amount) 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 62/1440 Fig. 2.2 The printing operation is performed by repeating the following sequence:(30/720 line feeding + 30 nozzle printing + 30/720 line feeding + 30 nozzle printing + 30/720 line feeding + 30 nozzle printing + 33/720 line feeding + 30 nozzle printing + 30/720 line feeding + 30 nozzle printing + 30/720 line feeding + 30 nozzle printing + 30/720 line feeding + 30 nozzle printing + 27/720 line feeding + 30 nozzle printing +).
