Preventive Maintenance Unimark Sprite
This section describes the preventive maintenance procedures for the SPRITE.
Although the SPRITE will perform dependably right out of the box, the operator must
do a periodic inspection and cleaning to keep it in good working order. With proper
care, the SPRITE enclosure, print head, magnetic encoder (when so equipped),
transport assembly, and other components can be expected to continue to provide
good service for many years. The following inspection and cleaning procedures are
presented separately for clarity, but may be performed at the same time.
Periodic Inspection and Cleaning
Like any piece of office equipment, the SPRITE ATB printer will need periodic
maintenance. Every three months or 12,000 coupons, the printer should
be cleaned and visually inspected. This process should take no more than ten
minutes.
Examine the enclosure's external and internal surfaces, ventilation slots,
transport assembly, and internal components for dust buildup. All dust should be
removed at least every three months to maintain performance.
Vacuum dust accumulation from the ventilation slots and other external
surfaces of the SPRITE.
Dampen a soft cloth or paper towel with a mild solution of soap and water or
a mild commercial cleaner and wipe the surface.
Dry the cleaned area with a clean, dry cloth or paper towel.
Dust is primarily produced by ticket stock passing through the transport
assembly inside the SPRITE enclosure. Clean the internal surfaces of the
enclosure as follows:
Toggle the POWER switch to 0 (OFF).
Unplug power cord from back of the enclosure
Unlock door on left side of enclosure and open to a maximum of 90º.
Remove all card stock from enclosure by rotating knurled knobs along
transport path as required.
Vacuum as much dust as possible from inside enclosure.
Use compressed air to blow dust from ticket stock path grooves in transport
assembly.
