ADDITIONAL CONSIDERATIONS

MACHINE MOUNTING ORIENTATION

The ink supply from the ink bottle to the ink pad is gravity fed on standard models. Any

mounting orientation is possible as long as ink is being fed by gravity. Rotation of ink

reservoir assembly will handle most mounting orientations. In upside down mounting

orientations (where the ink must feed against gravity) a wick is used in the reservoir

assembly to assure continuous feeding of ink to the pad (see diagram below).

Switches used to activate the machine can include but are not limited to the following

methods:

» mechanical / electrical timer

» proximity switch

» mechanical trigger switch

Since each customer can have a different preference, a common system is not supplied

for cycling the machine but left to the customer to determine the most ideal method.

A common way to signal retraction is to use a Reed / Hall effect switch (optional

magnent-on-piston air cylinder required) which senses a magnent on the piston (all

models except Model 22 / 28) has come into position at the bottom of the piston stroke.

Upon sensing the proximity of the magnent-on-piston a signal is sent to the four-way

valve to return the marking head to retracted position.

Another popular way to return cycle the machine to the ink supply position is utilizing

a micro-pilot actuator (installed on the rod-end port of the air cylinder) and flow controls

that restrict the flow of air. This switch senses the movement of air thru the line. When

the marking head is in full contact with the surface to be marked, the switch senses an

absence of air movement which immediately signals the four-way valve to return the

marking head to the retracted position. This switch is available as optional equipment

because of its uniqueness and applicability to the equipment operation.

A broad variety of inks are offered that are specially formulated for compatibility

with the Sprinter Marking machine. A complete stock of dye and pigmented inks to

mark virtually any surface, absorbent or non-absorbent is available in a range of colors

(including white) to suit customer needs. Alcohol-based dye and/or pigmented ink

grades meet most customer's requirements. Typically they dry-to-touch in less than

two seconds.
