Important Note: If acetone is used as a cleaning solvent, a second follow-up cleaning of the optical
surface using alcohol is required to remove any acetone residue. Use a clean lens wipe on each
pass. The wipe will pick up and carry surface contaminants that may scratch optical surfaces or coatings
if reused.

Troubleshooting Introduction
This section is designed to help isolate problems to the module level only. Problems on circuit boards or
the laser tube are not within the scope of this guide because they are not user-serviceable assemblies; do
not attempt to repair them. Contact NOVANTA® or a NOVANTA Authorized Distributor for repair or
replacement information.
To troubleshoot the 32-1 laser, it is necessary to understand the sequence of events that must happen
before the laser can turn on and operate. Before you attempt to perform any service, we advise you to
read the entire troubleshooting guide and review the relevant schematic diagrams. Symptoms and
possible causes are highlighted by dark print and bullet points throughout this section. Information about
each symptom and cause can be found in the paragraphs following each heading.
Caution: Possible Equipment Damage
Do not allow the nozzle of the air bulb to touch the optical surface. Any contact may damage the
optic by scratching coatings on the optical surface.
Do not use compressed shop air to blow contamination from the optic. Compressed air contains
significant amounts of water and oil that form adsorbing films on the optical surface.
Do not exert pressure on the surface of the optic during cleaning. Optical surfaces and coatings are
easily scratched by dislodged contaminants.
Use a new lens wipe on each pass as contaminants picked up by the wipe may scratch the optical
surface.
