ADJ X HEAD SLANT (B/C HEADS)

This function prints a check pattern (one-at-a-time for each head) to make
sure the printheads are installed straight up-and-down. Use the patterns to
determine whether one or both printheads need adjustment. To correct any
slant, use "Head Adjust Lever A" as described below.
1. Make sure "Adj: x Head Slant" appears in the LCD, and press the Enter
button. (x = B or C depending on the printhead) After the check pattern
prints, "x Slant Check End" (x = B or C head) appears in the LCD.
2. Compare the printed pattern with the illustration below. Press Enter if the
lines are parallel, as shown in the "OK" examples below. If there is a
slant, open the front cover, release the carriage lock by hand, and move
the carriage away from the carriage cap position.

back to the capping position by hand and close the front cover.
6. Select "Print Adj Pattern" with the SelecType or Item button, and print the
pattern again to make sure there is no slant. Adjust again if necessary. If
there is no slant, press Enter.
