Frequently Asked Questions

What does this 10 pack hold?

Ten 90X black cartridges, each individually sealed. It is print-room stock: the deep reserve a high-throughput room keeps so that a machine running dry mid-job is a thirty-second interruption, not a stopped line.

Which part number goes on the print-room stock card?

Record CE390X, the full part number; 90X is its short form and names the same cartridge. Writing the full code on the stock card keeps shelf labels, order forms and the printer's own supply page in agreement.

How does deep stock change a mid-run swap?

The operator walks to the shelf, not to a phone. With sealed units always in reach, the swap happens inside the run: out with the spent cartridge, in with the next, and the job continues while the empty goes to recycling.

How should ten cartridges be shelved?

Flat, sealed, in arrival order, away from heat and sunlight. A date on each carton end turns the shelf into its own stock record — the front unit is always the next one to fit.

What reorder floor suits a print room?

Set it by your busiest week, not your average one. Many rooms reorder when three sealed cartridges remain: enough to absorb a surge and a slow delivery at the same time. Adjust the floor once you know your room's rhythm.

What warranty and returns apply to the pack?

Each cartridge carries its own 1-year warranty and 1-year free returns, so one faulty unit is replaced or refunded without putting the other nine in question. Support is staffed Monday through Friday, 9 AM to 5 PM CST.
