Examine the test pattern for adjustment. Determine the
straightest set of lines.

 

Open the Top Cover and move the Angle Adjustment Lever to
match the number (or the square) of the straightest set of lines.
If no single set of lines is perfectly straight, move the Angle Ad-
justment Lever to a position between the numbers (or between
the number and the square) of the two sets of lines that are
least misaligned.

 

Close the Top Cover.
The Printhead is now straight, and adjustment is complete.

The Printhead height setting affects printing quality.
Specifying a low Printhead height makes images clearer and enhances printing quality but may cause paper to rub
against the Printhead.
