BC HEAD SLANT ADJUSTMENT (HEAD HEIGHT)
This function prints a check pattern that lets you adjust the vertical alignment of
Head C in relation to Head B. If the lines in the test pattern are not aligned, you
need to reposition Head C using the Head Adjust Lever shown in
Figure 5-6
.
1. Make sure "BC Head Slant" appears on the LCD, and press Enter.
2. Load a sheet of paper into the printer. The test pattern automatically prints.
3. Compare the printed pattern with the illustration below.
Press Enter if the adjustment is correct like the top row.
Otherwise, if the lines are staggered or uneven, open the front cover,
release the carriage lock by hand, and move the carriage away from
home position. Loosen the screw securing Head C, and move the
Head Adjust Lever left or right. Tighten the screw and then print
another test pattern to check the adjustment.
4. When done, make sure "BC Slant Check End" appears and press Enter.
Return the carriage to the capping position by hand and close the front
cover.
