Frequently Asked Questions

What's in the box?

Five 90X black cartridges, every one bagged and sealed. It is a cupboard quantity for one department: enough depth that the shelf, not the delivery schedule, decides when a printer gets its next cartridge.

Our floor mixes 600-series printers and M4555 copiers — does one pack serve them all?

Yes, and that is its main virtue. The LaserJet Enterprise 600 M601, M602 and M603 printers and the M4555 multifunction series all take the same cartridge — the CE390X, sold here under its short name 90X — so one shelf stock covers every monochrome machine on the floor.

How do we keep cupboard stock fresh?

Oldest first. Note the arrival month on the carton, always pull the longest-held cartridge, and leave the rest sealed — rotation takes seconds and keeps every unit in its prime when its turn comes.

Should cartridges be opened ahead of time to save minutes later?

No. The seal is what protects the toner; opening early saves nothing at swap time — the bag tears in seconds — and a cartridge sitting open in a cupboard only gathers dust and knocks.

What yield does each unit carry?

24,000 pages at standard coverage, per cartridge. Across a mixed fleet that translates into long, quiet stretches between orders — the cupboard needs attention a few times a year, not every month.

What cover applies to the pack?

A 1-year warranty and 1-year free returns stand behind each cartridge on its own merits: a problem unit is replaced or refunded individually. Questions are answered Monday through Friday, 9 AM to 5 PM CST.
