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. If the pattern confirms one or
both heads are offset, at a slant, use the corresponding "Head Adjust Lever A"
to straighten the slanted head.
1. Make sure "Adj: x Head Slant" appears in the LCD, and press the Enter
button. (x = B or C depending on the printhead)
2. After the check pattern prints, "x Slant Check End" (x = B or C head)
appears in the LCD. Compare the printed pattern with the illustration
below. Press Enter if the adjust level is OK like the top row shown 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. Next remove
the CR cover and loosen the installation screws in the affected head, then
correct the "Head Adjuster A" to correct the inclination. Then tighten the
head installation screws. The movement direction of the head adjuster at
this time is as follows depending on the degree of inclination. (The check
pattern color will differ during C head adjustment.)
