Frequently Asked Questions

My M4555f MFP says toner is low — how much printing do I actually have left?

More than the warning suggests. The low message on the M4555f is an early alert, triggered while a useful reserve is still in the cartridge — typically enough for days of ordinary office work. Treat it as your reorder signal, not an emergency: place the order when the message first appears and the replacement will be on the shelf before this cartridge truly runs dry.

Prints still look fine after the warning. Should I swap anyway?

No. Swap on output quality, not on the message. While pages come out dense and even, the CE390A still has work in it. The genuine end shows itself on paper — text greying, then fading unevenly across the page. Changing early throws away the reserve the rating already paid for.

Can I stretch a fading cartridge to finish a job?

Yes, once or twice. Power through the current job by removing the 90A, rocking it gently side to side to redistribute the remaining toner, and refitting it. That levels the powder over the drum and restores density for a short run. When fading returns after a shake, the cartridge is honestly finished.

Do copies fade at the same time as prints?

They draw on the same cartridge, so yes — a copy made through the document feeder fades on exactly the same schedule as a printed page. Scanning, by contrast, uses no toner at all. If scans look fine while copies wash out, that contrast confirms the cartridge, not the machine, is the problem.

What yield should I plan around between warnings?

10,000 pages at standard coverage for a full CE390A. An MFP that also copies heavily will move through that count faster in calendar terms than a print-only machine with the same page rating, because every copy is a page too. At $48.70 a cartridge, most offices simply keep the next one ordered when the warning shows.

What if the cartridge fades long before its rating?

That is a fault, not wear, and it is covered: the cartridge carries a 1-year warranty and 1-year free returns. Keep the faded output samples if you can — they help our team, available Monday through Friday, 9 AM to 5 PM CST, diagnose quickly. The shipping & returns page covers how exchanges move.
