Lexmark 248X ユーザーズマニュアル

Section 1: Introduction

Your printer supports the following burst print speeds in characters per 
second (cps).

Your printer uses dot-matrix impact technology to generate characters. The 248x 
has a 9-wire printhead. The 249x has a 24-wire printhead.

The 248x printhead has nine wires arranged in a single vertical column. The 
diameter of each wire is 0.30 mm (0.012 in.). The center-to-center distance 
between wires is 0.353 mm (1/72 in.). The printhead has an impact force 
sufficient to generate readable copies on multipart forms and envelopes up to 
and including 6-ply forms (original plus 5 copies).

The 249x printhead has twenty-four wires arranged in two parallel vertical 
columns of twelve wires each. The diameter of each wire is 0.22 mm (0.009 in.). 
The wires in each of the rows are vertically separated to produce a 0.141 mm (1/
180 in.) space between the centers of adjacent dots. The printhead has an impact 
force sufficient to generate readable copies on multipart forms and envelopes 
up to and including 4-ply forms (original plus 3 copies).
