Table 4-1. Required Adjustments - Epson Stylus Pro Service Manual

Stylus Pro Service Manual
4.1 OVERVIEW
This section describes adjustments required when the printer is disassembled and assembled after repair.
Since this printer has both black and color heads, it needs new adjustments not required for previous printers.
Refer to the following table to perform the appropriate adjustments.
r Always perform adjustments in the order indicated.
r After performing destination setting, head angle adjustment, head vertical position
head gap adjustment, or bidirectional adjustment, perform the cleaning
operation for the black and color printheads. The cleaning operation is necessary because
printing sample patterns for these adjustments 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 perform the following adjustments in the order shown:
(1) black head angle, (2) black-color head vertical, (3) head gap, (4) Bi-D alignment.
r After removing an ink cartridge, always install a new cartridge immediately. During
adjustments and testing, use the cartridges designed exclusively for service:
Monochrome: 1020626, CMY: 1020627.
