CHAPTER 5
REPLACEMENT PROCEDURES
This chapter consists of part replacement procedures for those items either found or suspected of
malfunctioning. These procedures cover the items checked during the troubleshooting
presented in the previous chapter. However, this manual does not cover all components and
only represents an attempt toward identifying a potential set of components. As a result,
servicing personal may discover additional items that warrant procedures.
3M Products encourages servicing personal to report these and any other problems in support of
continuous product improvement, publication of Tech Notes, and revision of this manual. For
servicing beyond the scope of this and the other 3M Max Secure publications, 3M Products
offers factory repair and Technical Support assistance as options.
As with all well-designed products, most parts should remain operational well beyond a typical
product life. Therefore, product abuse may cause most failures. In this regard, the operating
environment most likely acts as the prime factor influencing card-image quality, with airborne
particles the chief cause of problems. Servicing personnel should advise users to adjust cleaning
frequency to the rate airborne particles accumulate inside the printer and make sure that
someone at the site understands the use of the various cleaning materials. Users should replace
the outer sheath of the Cleaning Roller on a regular basis and anytime image problems appear.
Also, users should not ignore the CLEANING message for extended periods. Users should plan
a shut-down for cleaning as soon as possible.
Descriptions show how the various components fasten to the printer and the best sequence for
their removal. This makes the procedures reversible, meaning installation of a new component
typically occurs by reversing of the removal procedure.
