Gray / Dark Gray printhead for Designjet T7100

The HP CH647A is a new inkjet printhead supplying gray and dark gray channels. It is built for HP Designjet T7100 series large-format printers used in technical and graphic environments. The unit installs directly into the carriage to restore native colour fidelity. Sold as a single each.

For owners maintaining a T7100 series printer

This part suits technicians or operators replacing a worn or clogged gray / dark gray printhead on a compatible Designjet. It will not fit printers outside the T7100 series, nor does it provide other ink colours or a full printhead set. Buyers needing cyan, magenta, yellow, matte black or photo black channels must source the corresponding printheads separately.

Ink colour channels: gray and dark gray only

The printhead delivers exactly two channels — gray and dark gray — which together produce neutral grays and subtle tonal transitions in CAD, GIS and presentation output. If your workflow requires a different colour pair or a complete six-channel configuration, this CH647A unit alone will not meet that need.
