ADJUSTMENT PROCEDURES
To maintain optimum performance and print quality, periodically mechanical adjustments will
have to be made. These adjustments are typically required following the replacment of a
component.
Other adjustments may be required due to variations in media size or quality and due to different
print image denseness. Instructions relative to those conditions are not covered here. Refer to
the Installation and Operation units for those relative instructions.
This chapter provides instructions on the performance of those activities that are mechanical in
nature and are responsive to maintenance activities. The table below provides common print
defects and their relative cause.
