Step 14 : Implement the “Color Head Tilt Verification”. (Refer to “Check Color Head Tilt”)
This will run unidirectional printing with four colors. Here, Head Adjuster A is used to adjust the
depth of the Color Head relative to the Black Head.
Step 15 : Check the printing and move the carriage to the centre. If the cyan or yellow printing appears is
more forward than the black printing, slide Head Adjuster A up and fasten it. If the opposite
applies, slide it down. When fastening the Print Head, push it towards the taper of the Head
Adjuster A for depth and towards the taper of Adjuster B for tilt. (The scales on Head Adjusters A
and B represent a change of about 0.1 mm per graduation.)
Step 16 : Implement the “Color Head Tilt Verification”.
Repeat Steps 13 and 14 until the positioning matches that of the Black Head.
Step 17 : After completing the Black Head and Color Head positioning adjustment, return to the previous
menu level.
Step 18 : Implement “Repeatability Printing Positioning”. (Refer to “Aligning Repeatability Printing Position”)
This will run single-pass, bidirectional printing three times and compensate for any offset of the
second line (CCW printing) relative to the first and third lines (CW printing).
Step 19 : Check the printing and enter a positive value to move the second line (CCW printing) towards the
Cap, or a negative value to move it in the opposite direction. Register first for Black, then for
Color. (After registering, follow the message on the LCD.)
Repeat until all bidirectional printing is aligned.
