Printhead
Thick film thermal printhead
(with thermal historical control)
KF2006-GM50A
GM50 series is the new product that newly added the future history control and driver LSI which has the function of
thermal historical control, to GL50 series which is employing the conventional thick-film fast response thermal element.
!Applications
High speed label printer
High speed bar code printer
High speed ticket printer
Various high speed terminal printers
!Features
1) Newly developed thick-film fast response thermal element and driver LSI with the function of thermal history control
which is added the future history control are employed for this series. It is possible to print with super high speed of 10
inches / s or 250 mm / s.
2) 150km life realized by attributing durable new protection film.
3) New partial glaze construction makes it compatible with the thermal transfer application.
4) Market-proven G-series printhead construction ensures high reliability.
