4-5-3 Confirmation test
<Confirmation test>
Using Photo Paper Pro, and with the paper thickness lever set to the left position (normal
position), print an image and confirm that the print quality is proper, and the ink cartridges are
free from contacting the paper.
If the print quality is not proper, or an ink cartridge contacts the paper, adjust the head-to-paper
distance in the following procedures:
<Procedures for adjusting the head-to-paper distance:>
1. At the bottom edge of the boss beside the red screw on each side of the chassis, put a mark
to indicate the current position.
2. Loosen the red screws, and adjust the head-to-paper distance.
To prevent the ink cartridges from contacting the paper: Raise the carriage rail from
the current position.
To improve the print quality: Lower the carriage rail from the current position.
(See the step 1 of the carriage rail adjustment
Part 1 - 33
