Xaar XP55500016 XUSB Drive Electronics Board for Xaar 1003 Printhead

Product Overview

The Xaar XP55500016 is an XUSB (Xaar Universal Serial Bus) drive electronics board designed to control Xaar 1003-series industrial inkjet printheads. It serves as the interface between the system controller (impulse generator) and the printhead, generating the precise high-voltage waveforms needed for drop ejection. This board is a critical component in digital inkjet printing systems for labels, packaging, ceramics, and direct-to-shape printing.

• Mounting: Chassis mount with standoffs

Integration into Industrial Printing Systems

The XP55500016 is typically installed in a printing system’s electronics enclosure, near the printhead. It receives image data from a formatter board or PC via USB, and generates the digital signals that control each nozzle’s firing. The board’s onboard processor manages the timing of multiple channels, enabling high-frequency drop ejection (up to 32 kHz for Xaar 1003). The board also monitors printhead temperature and health, reporting back to the host.

Waveform Customization

Using Xaar’s software tools (e.g., XaarDrive SDK), system integrators can create custom drive waveforms for various inks and operating conditions. The waveform can be tuned to optimize drop velocity, volume, and satellite control. The XP55500016 stores multiple waveform sets in its non-volatile memory, allowing switching between different print modes (draft, production, high-quality).

Printed Circuit Board Construction

The board is designed for reliability in industrial environments. It features conformal coating to protect against humidity and dust. Large heat sinks and a fan header (optional) help dissipate heat from the high-voltage drive stages. Connectors are keyed to prevent misconnection.

Applications

• High-speed label and packaging printing

• Ceramic tile decoration

• 3D object printing (cylindrical items, bottles)

• Textile and banner printers

• Fluid dispensing systems

Troubleshooting and Replacement

Common failure modes include damaged high-voltage output channels (due to shorted piezo actuators) or USB communication loss. Replacement requires careful handling due to static sensitivity. Always use an anti-static wrist strap when handling the XP55500016.

Conclusion

The Xaar XP55500016 XUSB drive electronics board is a high-performance, robust solution for driving Xaar 1003 printheads in demanding industrial inkjet applications. Its flexible waveform capability and high-speed data handling make it central to modern digital printing systems.
