5.3 Lubrication
The SNAP 500 printer has ball bearings that do not require lubrication. However,

feed assembly that do require lubrication.
Figure 18a: Lubrication Locations
Caution: AVERY DENNISON recommends lubricating the
bronze bushings with one drop of multi-use oil once every
month during normal operation.
5.4 Rotary Knife Assembly

mounting bracket and is locked in place with a single screw. You can expect an

cuts if you are cutting coated tapes. Knife life decreases when foreign objects are
inserted into the assembly.
There are no field replacement components. When the blades become dull,
replace the rotary knife assembly. Replacement knife assemblies are sold ready
to install with no adjustments required.
