Which toner fits the HP LaserJet M436dn?

Monochrome laser · machine reference 2KY38A

The HP 56A toner (CF256A, about 7,400 pages) or the 56X (CF256X, about 13,700 pages), and a 57A drum (CF257A) rated for 80,000 pages. That last figure is the one to remember: nearly eleven standard toners for a single drum, the widest ratio in the whole catalogue.

Eleven toners to one drum

On small lasers the drum is shut inside the cartridge: every toner change renews a part that could have lasted far longer, and you pay for it every time. It is convenient, and it is expensive.

The M436dn separates the two. You buy powder when you run out of powder, and the cylinder — the expensive part — is replaced once in eleven times. That is most of the reason why a machine of this type, dearer to buy, works out clearly cheaper per page than a compact laser.

The drum is not eternal for all that. It scratches and marks, and its signature is recognisable: a fault that always comes back at the same place on the page. A toner at the end of its life, by contrast, gives uniformly pale pages.

A3, and what the format changes

The M436dn prints, copies and scans up to A3, at 23 pages per minute, with automatic duplex. Since toner yields are measured on A4 pages, output entirely in A3 uses twice as much: a 56A there produces about 3,700 pages rather than 7,400. The subject is developed on the LaserJet Enterprise 700 M712dn page, the catalogue's other monochrome A3 machine.

56A or 56X

13,700 pages against 7,400, so 1.85 times more. On a machine whose cycle reaches 50,000 pages a month, the 56X is the natural format: it halves the number of interventions on a printer that weighs 25 kg and is rarely within arm's reach.

Frequently asked questions

Is the 57A drum changed at the same time as the toner?
No. It holds 80,000 pages against 7,400 for a 56A: you will change about ten toners before the drum comes into question. Replacing them together means throwing away an almost new part.
How do I know whether the fault is the toner or the drum?
Look at how regular the fault is. Uniformly pale pages or light bands come from the toner. A spot or a line that comes back at exactly the same place on every page comes from the drum — the cylinder has a fixed circumference, so the fault repeats at a constant interval.
Will a 56A toner fit a LaserJet Pro 4003?
No. The 4003dn takes a 151A, with no separate drum. Both machines are monochrome and of neighbouring class, but their consumables have nothing in common.
