Citizen CL-S621/631 Thermal Label Printer

The devices of the CL-S621/631 family provide absolutely professional production of labels and tickets using either direct thermal or thermal transfer printing. This flexible solution combined with the printers’ high performance guarantee smooth integration into almost every application.
These desktop printers can handle small to medium-sized labels with a maximum width of 118 mm. The CL-S621 prints pin-sharp logos, pictures and barcodes particularly efficiently with 8 dots/mm (203 dpi), the CL-S631 with 12 dots/mm (300 dpi). A speed of up to 150 mm per second always ensures fast production and impresses with short waiting times.

The entire printhead mechanics is based on a sturdy metal structure that opens wide enough to make roll and ink ribbon changes as easy as possible. With thermal transfer ribbons of up to 360 m in length, print about 6,800 labels without ink ribbon changes, reducing interruptions to a minimum. The adjustable media sensor has been optimised in the new version and guarantees absolute accuracy as well as hundred percent correct placement, which is critical for frequently changing media. High reliability, durable, stable construction and the extendible, adaptive concept make the Citizen CL-S621/631 a first-choice label printer.

Patented features further impress through first-class performance: the ARCP system regulates the ink ribbon tension automatically during thermal transfer printing, thus preventing wrinkled ribbons and subsequent failures. The printer switches automatically between the Datamax, EPL and ZPL languages. Together with the up to 16 MB flash memory, this cross-emulation guarantees you a number of applications. The CL-S621 comes standard with integrated serial and USB interfaces. Optionally, you can also install a parallel, Ethernet or Wi-Fi card for optimal connection to existing infrastructures. Equipped with a tear-off edge in the standard version, the desktop printers can be retrofitted if needed with easily-installed label dispensers or cutters. This is especially useful for ticket and other applications where tags and continuous feed media are cut into predefined lengths.
