B HEAD SLANT/C HEAD SLANT ADJUSTMENT (HEAD ANGLE)
This function prints a check pattern that lets you adjust each printhead straight
up-and-down. If the pattern shows staggered or uneven lines, the printhead is
misaligned. Use the printhead’s adjusting lever as shown in
Figure 5-5
to
straighten it out.
1. Make sure "Adj: x Head Slant" appears on the LCD, and press the Enter
button (x = B or C depending on the printhead).
2. Load paper if not already loaded.
3. The check pattern prints and "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 adjustment is correct like the top rows shown below.
If the adjustment is incorrect, open the front cover, release the carriage
lock by hand, and move the carriage away from home position. Loosen
the screw securing the head that is printing at a slant, and then move
the Head Adjust Lever left or right depending on the slant direction.
Tighten the screw and print another test pattern to check the
adjustment.
4. After adjusting both heads, move the carriage back to the capping position
by hand and close the front cover. Make sure "x Slant Check End"
appears, and press Enter to conclude the adjustment.
