Frequently Asked Questions

The M4555fskm is the fully loaded model — does it use a different cartridge?

No. However the machine above it is configured, the supply bay takes the same cartridge: the CE390X high-yield black unit, also called the 90X, rated at 24,000 pages. Confirm the code on your current cartridge and it will read CE390X, exactly as listed here.

Which of the fskm's functions draw on this cartridge?

Printing and copying — the two functions that put toner on paper. Scanning, fax reception to memory and the machine's document-handling features use no toner. In a busy fskm installation, walk-up copying is often the largest single consumer, so its volume belongs in your page estimates.

How should a high-use MFP like this manage its spare?

Keep one sealed CE390X at the machine and treat fitting it as the reorder trigger. At 24,000 pages per cartridge, changes are infrequent, but on a machine serving a whole department an empty supply idles every function at once — the spare is cheap insurance against that.

Describe the actual swap on the M4555fskm.

Open the top cover, lift the spent cartridge out, pull the sealing strip from the new 90X, slide it in until it seats, and close the cover. None of the finishing, scanning or fax hardware is involved, no settings change, and the machine returns to ready on its own.

Will pages fade before the cartridge stops completely?

Yes — fading is the early warning. Text greys gradually as the toner runs down, and a gentle side-to-side rock of the cartridge typically restores even density for a final stretch of work before the replacement genuinely has to go in.

What terms cover this cartridge?

A 1-year warranty and 1-year free returns, with support available Monday through Friday, 9 AM to 5 PM CST. If the unit supplied for your LaserJet M4555fskm arrives damaged or fails early, it is replaced or refunded.
