Tentative SE3002-DC90A
Printheads Under development

High speed thermal printhead
(300 dots / inch)

SE3002-DC90A

High speed, high quality, and high durability are achieved by using step free structure with high performance partial glaze
and highly conductive overcoat la yer. SE300*-DC 90A series are lined up which can accommodate with all types of
barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).

zApplications

Bar code printer
Label printer
Packaging printer
ATM
Ticket printer

zFeatures

1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high ef ficiency.

2) Standard glazed components to accommodate thick paper.

3) High speed clock to facilit ate external hea t history control.

4) Using a hard conductiv e film as a protective film on t he heating element offers excellent resistance to electrostatic

damage.
