Frequently Asked Questions

What kind of check volume justifies five cartridges at once?

Volume with many destinations: a property-management office or a firm paying out across dozens of accounts prints checks in long batches, and this 90X-MICR (CE390X) five-pack keeps that line supplied without a standing weekly order. Each cartridge is rated at 24,000 pages.

How do we stop MICR and standard cartridges being mixed up in a busy stockroom?

Label the shelf, not just the box. Keep the MICR units on their own marked shelf or in a labelled bin, apart from the standard 90X stock for the same machines; the cartridges look alike, and a standard unit fitted on check day is a wasted run. A strip of coloured tape on each MICR box settles it at a glance.

Which printers draw from this pack?

Any on the CE390X platform — LaserJet Enterprise 600 M601, M602 and M603 printers and the M4555 series, including the Enterprise M4555f. A five-pack commonly feeds two or three check stations across one office.

Does a big batch run change the bank-acceptance picture?

The rule is the same at any volume: acceptance is not guaranteed by the toner. Before a new cartridge or a new box of check stock enters service, print test checks on that stock and confirm readability with your bank — once per change, not once per batch.

How long can sealed cartridges wait on the shelf?

Sealed, flat and kept in a cool, dry room, they wait well. Work oldest-first, note arrival dates on the boxes, and do not strip seals until a cartridge is actually going into a printer.

What happens if a unit underperforms?

Each cartridge is covered by a 1-year warranty and 1-year free returns, judged on its own output. Support is staffed Monday through Friday, 9 AM to 5 PM CST.
