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.
