Xaar 501 GS8 Printhead

Xaar 501 GS8 O Printhead - XP50100009

The new Xaar 501 printhead reaches higher levels of performance in inkjet graphics. Whether printing large exterior banners or indoor point-of-sale material, this premium printhead delivers exceptional print quality, excellent reliability, and high production up-time. Value-added effects such as printing on transparent or colored substrates or adding varnishes are made easy with the Xaar 501.

The new and unique PrecisionPlus™ architecture of the Xaar 501 builds on Xaar’s incredibly successful Hybrid Side Shooter™ architecture. This new architecture optimises the actuator performance giving more uniform drop formation across the print swathe and therefore exceptional print quality for stunning graphics.

PrecisionPlus architecture flips the PZT’s (Piezo actuators) supporting substrate on its side so the PZT is on the edge of a rigid block of the substrate. This architecture means that there is more stiffness in the z-axis (better support for the PZT).

The Xaar 501 GS8 O is suitable for oil-based printers with a vacuum (gravity) fed mode ink system. The last chance ink filter fitted on the inlet port avoids particles, debris or air bubbles get into the printhead.

The Xaar 501 GS8 O has a WFG (wide format graphic) nozzle guard which is closer to the actuator providing protection from substrate damage. This nozzle guard wraps around the front of the actuator.

The Xaar 501 GS8 O can be used as a replacement to Xaar 500/40 printheads (discontinued). An ICM (Interface connection module) enables X500/40 based printers to communicate with Xaar 501 printheads. The ICM requires a waveform loaded onto it by Xaar. In many cases, the ink system of the Xaar 500/40 based printer will also need some modification as Xaar 500 printheads have 4 ink feeds whereas Xaar 501 printheads have 1 ink feed). Our engineer team can help implementing these changes to migrate existing printers from 500/40 to 501 printheads.
