1. UNPACKING

Each printer mechanism is packaged in an antistatic bag. Observe precautions for handling in

electrostatic protected areas.

2. OVERVIEW

Based on static thermal printing technology, the CM/XM series is a family of user-friendly, highly

reliable devices which have been specially designed to fit in the minimum space.

CMxx : Printer only or printer with optional tear bar cover

XMxx : Printer with cutter

Very small size printer and cutter

Silent mechanism

Option of 4 dots/mm or 8 dots/mm print-heads

Optional cover with tear bar

Optional cover with Guillotine cutter (XMxx)

Easy to connect (only one connector for motor, printhead, opto-sensor and cutter)

Front and bottom paper introduction possible

Optional drive for paper rewinder
