Frequently Asked Questions

Which cartridge should be on the purchase order for an M603dn?

CE390A — the cartridge HP also sells as the 90A. It is the single black supply for the LaserJet Enterprise 600 M603dn, priced at $48.70 with a rated yield of 10,000 pages. If your stores system shows either number, it is pointing at this unit.

Our M603dn duplexes statements by the thousand. How is yield best estimated?

By printed pages, which is what the 10,000-page rating counts. Duplexing halves the sheets an M603dn consumes but each side still draws toner, so a 10,000-page cartridge covers roughly 5,000 two-sided sheets at standard coverage. High-coverage statement layouts will bring the real figure in below the rating.

The supply warning appeared in the middle of a statement run. Now what?

Keep going — the warning is set with reserve in hand. Should pages begin to wash out, pause, remove the cartridge and rock it side to side to level the toner, then finish the run. Fit the fresh CE390A once the deadline has passed rather than stopping mid-batch.

Is there anything model-specific about fitting toner in the M603dn?

Nothing beyond the standard 600-series routine: cover up, spent cartridge out by the handle, seal off the new cartridge, slide it home. The duplex unit and network board are not touched by a toner change, and the job takes about two minutes.

Does this cartridge also serve our other 600-series machines?

Yes. The CE390A is the shared supply across the Enterprise 600 family and the M4555 multifunction series, which is why a spare bought against the M603dn can be redeployed to any sibling machine that runs dry first.

What backing does the cartridge come with?

A 1-year warranty and 1-year free returns: early failure, leaks or streaking from new are grounds for a replacement or refund. Questions are handled Monday through Friday, 9 AM to 5 PM CST.
