DESCRIPTION OF THE MECHANISM
The main characteristics of the series CM thermal printing mechanism are
definitely the reliability, the quality and the long lasting performance, making it
the suitable product for industrial environments such as weighting, control,
safety systems, as well as medical and portable applications.
The sturdy aluminium alloy casing for a higher thermal efficiency and a much
better rigidity of the structure.
The series CM mechanisms prints at a high 203 dpi resolution on paper
weights between 58 and 80 gr/m2(also labels).
The mechanism is featured with a high torque paper-pulling motor, and with a
silicon rubber roll.

2. PRINT HEAD
CMxxx2-1
2.1 PRINT HEAD
CMxxx has a thickfilm thermal printhead. Scanning Line Time (SLT) is the
time to print one complete line using all strobes available.
The relation between the printhead supply voltage and “On Time” (Ton) is as
follows:
oI=oP
2
=vaRx daeHV
2
vaRx
)ciR+vaR(
2
=noT oE
oP
2.2 OPERATION PRECAUTIONS
1. When continuous printing is performed the supply energy should be
reduced so that the substrate temperature show in Maximum Condition
Table
2. Power On and Off sequence must be in the following order to prevent the
dot element damage: Turn On= Apply the logic supply voltage (Vdd) first
and then the printhead supply voltage. Turn Off= Switch off the printhead
supply voltage first and then turn the logic voltage off.
3. The printhead shall be disabled in STB during Power ON/OFF, or Power
(VH)-Logic(Vdd) sequence described in note 2 shall be kept.
4. Heat elements and IC’s shall be anti-electrostatic in order to prevent the
electrostatic destruction. Do not touch the connector pins with naked
hands.
5. The printhead substrate surface is coated with glass and mechanical
stress or shock (including dust scratch damage) should be avoided to
prevent damage.
6. When the printhead operation is finished, printsupply voltage (including
the charged voltage with capacitor) should be reduced to the ground level
and remained until next printhead operation occur.
7. Condensation should be avoided. If condensation occurred, do not switch
on the printhead power until condensation disappear.
8. If printing sound, for example sticking sound, occured, please adjust the
paper feed speed or pulse to avoid these kind of mechanical resonance.
9. Please pay attention that the paper used does not include bad factor to
affect printhead life.
