Introduction
Repair-Adjustment Initial Issue
Introduction Overview The Repair / Adjustment section, Section 4 of the Service Manual, provides information that
enables the Service Representative to restore the product to within specification after fault iso-
lation.
Section Contents The Section Contents lists, in sequence, all the items of the section, with page references.
Each entry in the section contents appears exactly as it appears in the manual.
Repair Procedures This repair subsection contains instructions for removal and replacement tasks. A removal and/
or replacement task is included when it is not obvious how components are removed and
replaced, or when special conditions (such as an adjustment) must be met during these tasks.
Step-by-step removal procedures for a specific component or assembly are provided. Numbers
in the illustrations refer to steps in the procedure. For example: if step 3 in a procedure
instructed you to remove a screw, the screw in the illustration would be labeled 3.
Illustrations are used to assist you with the procedures. You should refer to the specific Parts
List illustration (listed under the repair title) for locating most components within a procedure.
NOTE: Always reinstall the correct type and size screws. Using the wrong screw can damage
tapped holes.
NOTE: Do not use excessive force to either remove or install a part.
Locations, such as left, right, front, or rear, given in the repairs assume you are facing the
printer Control Panel.
Adjustment The N2025/2825 printer does not contain any field adjustable components.
WARNING
Use of controls or adjustments other than those specified in this manual may result in
an exposure to dangerous laser light.
