Unit 1: Introduction

GENERAL DESCRIPTION

The MB200/201i are compact, transportable printers designed for frequent, but intermittant use. Their direct thermal print head not only allows high performance two-color printing (with special media), but also clear barcode printing.

Their ABS housing provides a durable, impact-resistant product. An intergrated dispenser enables application of labels upon print. Rechargeable battery packs and a DC power transformer ensures operation anywhere, under any conditions. An automatic power off function turns the printers off after the last print.

THEORY OF OPERATION

When activated, the media is fed past the print head by an integrated drive train. The drive train is electric motor driven, coupled to a gear configuration located on the left side of the printer chassis. Kinetic energy is transferred to a platen roller which is the driving force of media movement. Paper guides within the chassis assembly ensure that the media remains properly positioned during the printing process and is fed unimpeded through an opening in the front.

A series of strategically located sensors sends signals to the processing unit. The processing unit in turn sends response signals to the various features based on programmed and received data.

Correct signals initiates print head activity.
