4.1 OVERVIEW
This section describes adjustments required when the printer is disassembled and assembled after
repair. Since this printer has both a black and color head, it needs new adjustments not required for
previous printers. Refer to the following table to perform the appropriate adjustments.
WARNING
❏Always perform the adjustments in the order indicated.
❏After performing steps 1-5, perform a cleaning operation for the black and color
printheads. the cleaning operation is needed because printing sample patterns for the
head angle, Bi-D alignment, and the head gap increases the viscosity of the ink, and the
printer will not print the correct value. For instance if you replace the black head, you
must do the following adjustments in the order shown:
(1) Black head angle, (2) black-color head vertical, (3) head gap, (4) Bi-D alignment.
❏After removing an ink cartridge, always install a new cartridge immediately. During
adjustments and testing, use cartridges designed exclusively for service
(Monochrome: 1020626, CMY: 1020627).
