Pigment black printhead for porous media

This HP Q7456A printhead uses TIJ2.50 technology to deliver 600 dpi output through 300 nozzles firing at up to 12 kHz. The aqueous pigment ink formulation provides high optical density and water resistance on porous substrates. It is built for both intermittent and high-volume printing environments.

Suited for coding and marking on porous surfaces

Operations needing durable black codes on cardboard, paper or similar porous materials will benefit from the long decap time and pigment stability. Buyers who require colour output, non-porous substrate adhesion or solvent-based ink chemistry should look at alternative printhead assemblies.

300-nozzle array at 600 dpi resolution

The fixed 300-nozzle configuration at 600 dpi determines the maximum print swath and native resolution available in a single pass. This specification decides whether the printhead matches the required print width and detail level for the target application.

Questions about this item

What clearance does the 2 x 4.5 x 7 printhead need inside the printer?

The unit measures 2 by 4.5 by 7 and mounts with the nozzles facing up or to the side, so allow space for that orientation and the connector assembly.

How do I install the HP Q7456A printhead without damaging the connector?

Align the printhead with the carriage, press firmly until the connector seats fully, then run the printer's alignment routine; skipping the alignment step causes misregistration.

When should I replace the TIJ2.50 printhead after printing with pigment black ink?

Replace it when nozzle checks show missing lines that cleaning cannot restore; the 300-nozzle head is rated for 12 kHz firing and long decap time, so life varies with volume and idle periods.
