Original StarFire SG1024/SC Printhead

The StarFire™ SG1024/SC is a compact, self-contained unit built to withstand the harsh environment of industrial ceramics production. It uses field proven materials to deliver consistent output over a long service life with continuous ink recirculation and two-color operation at 400 dots-per-inch. Equipped with a single replaceable metal nozzle plate that is designed to withstand abrasion and resist damage. The unit is compatible oil-based ceramic inks.

Combining superior jetting performance with a high nozzle packing density in a compact, self-contained unit, the StarFire SG1024 uses field proven materials to deliver a long service life with consistent and reliable output.

Each SG1024/SC printhead has 1024 independent channels arranged in 8 rows in a single nozzle plate for single color operation at 400 dpi.

Equipped with a singular, durable, collar mounted, metal nozzle plate to withstand abrasion and resist damage, it is removable for cleaning or replacement. The printheads are available in extra small, small, medium and large drop sizes. Fujifilm Dimatix’ breakthrough VersaDrop allows multiple fixed drop sizes in binary mode and grayscale capability from one printhead, with no loss to productivity. In binary operating mode, the SG1024 SC 1C Ceramic printheads are designed to eject adjustable drop sizes from 12 up to 33 picoliters and can support grayscale levels as defined by the user’s control electronics.

The StarFire SG1024 Ceramic printheads are compatible with oil based ceramic inks and maintenance fluids. Using RediJet technology, the SG1024 continuously recirculates inks through the printhead at the nozzle and refill chamber to increase open time, reduce downtime and improve startup, especially for highly pigmented and fast drying inks. RediJet allows StarFire printheads to be quickly and easily primed with minimal ink waste thereby increasing the inherent productive capacity of the printing system by reducing maintenance times and associated costs.

The StarFire SG1024 printhead has simplified interfaces. The electrical interface consists of one 60-pin connector located topside for power, ground, data, control signals and fire pulse. Two fluid connections facilitate easy priming, flushing and continuous ink recirculation and connect to an ink supply via Luer fittings.

Heating configuration includes an internal heater/thermistor for precise control of ink viscosity at temperatures up to 50°C. Precise registration points enable drop-in alignment with customer provided mounting features, reducing set-up and alignment costs during printhead replacement and also allow multiple printheads to be accurately arrayed into print bars for wide width, higher resolution and multi-color printing devices.
