Aster Graphics Inc 4 Pack 58X CF258X Black Toner Cartridges 10000 Pages

Ready-to-use 4-pack for HP 58X printers

This set contains four black toner cartridges built to replace the HP 58X CF258X series. Each unit ships new with its own chip so the printer recognises it immediately. The cartridges are manufactured to ISO 9001 and ISO 14001 standards and come with a two-year shelf life. Installation follows the normal printer routine and needs no special tools.

Offices that print mostly monochrome documents

The 10 000-page yield per cartridge suits departments that run high-volume black-and-white output on the listed LaserJet models. Buyers who need colour toner or who operate printers outside the M404, M406, M428 and M430 families should look at other supplies. The pack is not designed for inkjet hardware or for machines that take a different HP cartridge series.

10 000 pages per cartridge at 5 % coverage

This yield figure is the single number that tells you whether the pack matches your print volume. If your monthly output is far lower the toner may sit unused past its shelf life; if it is far higher you will replace cartridges more often than expected. The rating follows the standard ISO test method quoted in the specifications.
