NShi PGI-280XXL CLI-281XXL 5-pack ink cartridge

Five-cartridge set for Canon PIXMA printers

This pack contains five aftermarket ink cartridges built to replace Canon PGI-280XXL and CLI-281XXL models. It supplies one large black PGI-280XXL cartridge, one small black CLI-281XXL cartridge and one each of cyan, magenta and yellow CLI-281XXL cartridges. The set fits a wide range of PIXMA TS and TR series inkjet printers used in homes and small offices. Buyers who need the Photo Blue cartridge that some PIXMA models require will not find it in this pack.

Thermal performance and power use

Ink cartridges have no moving parts, fans or electronic circuits that generate measurable heat or noise during printing. The printer itself manages ink delivery and head heating, so the cartridges add no thermal load or acoustic signature of their own. Power draw is determined entirely by the printer's own supply and is unaffected by the choice of compatible cartridges. No thermal, acoustic or electrical specifications apply to the cartridges themselves.

Bundled chips enable printer recognition

Each cartridge carries an integrated circuit chip that communicates ink levels and authenticity data to the printer firmware. This allows the PIXMA models listed to display remaining ink estimates and to accept the cartridges without manual overrides. The chips do not alter print resolution, colour gamut or drying time; they only provide the handshake the printer expects. No additional software, drivers or maintenance tools are included in the package.
