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.

4.Using tweezers, or a similar tool, push in the head toward the back of the printer, and then tighten the screw.

5.After making sure both heads are correctly installed, move the carriage 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.
