2.0 Thermal Print Mechanism<br />

The thermal print mechanism is a Seiko model LTP3245 Thermal Printer Mechanism.<br />

2.1 Thermal Print Head<br />

The pdnter mechanism contains a thermal print head is a 384 dot thermal<br />

element. It has a 2.28 inch (58mm) wide paper path with a print width of 1.89<br />

inches and a resolution of 203 dots per inch. Print speed is rated at 1 to 2<br />

inches per second.<br />

2,2 Feed Mechanics<br />

The feed mechanics consist of a geared stepping motor driving a rubber platen<br />

roller. Feed rate is approximately 2 inches per second. On the side of the roller<br />

is a manual feed knob for assistance in paper loading. Also next to the manual<br />

feed knob, there is a lever to raise the print head off the platen to allow for<br />

pushing the paper through the mechanism and clearing jams.<br />

2.3 Sensors<br />

There are three sensors on the print mechanism. The paper presence sensor is<br />

an infrared reflective device located in the bottom of the mechanism at the<br />

paper entrance. The head up sensor is a mechanical switch that is cam<br />

actuated by the head up lever. Head temperature detection is via a thermistor.<br />

All three sensors signal the controller interface electronics to inhibit printing.<br />

3.0 Interface Controller Electronics<br />

The interface controller electronics is responsible for communicating with the host<br />

controller and managing the print mechanism and paper cutter. The primary functions<br />

are explained below. The controller must be of a page mode printing type architecture<br />

which supports coupon creation and storage in the controller memory. There must be<br />

some type of non-volatile memory, resident on the controller, to allow retention of<br />

coupons in the event of power loss.<br />

3.1 Functions<br />

The main function of the controller electronics is to provide a communications<br />

interface with the vending machine controller (VMC), the program port, and to<br />

control the thermal printer mechanism via the thermal head and ddve motor. It<br />

controls speed and print density using a power monitoring function to prevent<br />

overload of the system power supply. Further, it monitors the print mechanism<br />

sensors to inhibit or modify printing as necessary.<br />
