2-6-5. Firing Adjustment of the Print Heads

When Print Head preparation is complete, adjust the firing timing to improve print quality. The Print Heads
operate bi-directionally, and therefore the timing of the firing is essential in order to obtain sharp, vibrant prints.
Failure to adjust the timing properly may result in a loss of detail such as single vertical straight lines being
printed as 2 lines. Consequently, printed images will become dull and hazy, and some colors will be granular
with dots of ink color. Due caution is thus advised when adjusting the timing.
Execute the Firing Adjustment in "GT-3 Maintenance Tool".

Prepare several sheets of A4 or letter-sized white paper in executing Color Print Head adjustment.
