The HP 774 printhead for DesignJet is a single-pack printhead module with dedicated Photo Black and Light Gray pigment nozzles designed to restore accurate black and gray output for large-format photo and grayscale printing.

How to use

Power off the printer or follow the printer’s on-screen instructions for safe printhead replacement.

After installation, follow the printer prompts to align and charge the new head if required and run any recommended cleaning or calibration cycles to ensure optimal output.

Recommendations

For best long-term performance, use Original HP pigment inks and perform routine maintenance cycles as recommended by the printer’s manual. Store unused printheads in their original packaging at room temperature and install promptly to avoid contamination. When producing high-volume photo or grayscale work, periodically inspect nozzle health and run automated nozzle checks to maintain consistent image quality.
