COURSE ADMINISTRATION

OVERVIEW
Okidata developed this course in order to provide the information necessary to install and
maintain the Pacemark 3410. Upon successful completion of this training course, you will be
able to do the following.
Install and operate the product
Locate the major assemblies of the product
Identify fault indications
Perform corrective and preventive maintenance
The Service Handbook is the primary reference manual for this course. You cannot, however,
successfully complete this course by referring only to this manual. Take the time to familiarize
yourself with all of the documentation in the training kit. This additional information will
greatly simplify working with the product.
Okidata’s Technical Training Program is designed to build a knowledgeable and efficient
service and support group for Okidata products.
One step in becoming an Authorized Okidata Service Center is obtaining a training kit for the
appropriate product. This acquisition allows the Dealership to have reference materials
available during service jobs. Having, and using, these reference materials will minimize the
time and money spent on repairs.
Technicians complete Certification Tests as part of Okidata’s Authorization process. Testing
familiarizes the technician with the product and reference materials.
This training course provides assembly level repair information to the field technician. No
attempt is made to provide basic training in being a technician. This kit strives to train a
technician to service the product. Okidata views service technicians as representatives of
Okidata. Through this course, Okidata seeks to provide the means and the motivation that will
make good service a reality.
Remember
Component level servicing is provided only at Okidata Service Repair Depots!
