Frequently Asked Questions

Which toner cartridge does the LaserJet 4240N use?

The LaserJet 4240N uses the Q5942A (standard yield) or the Q5942X (high-yield) toner cartridge. Confirm the code printed on your current cartridge matches before ordering a replacement.

Can the LaserJet 4240N be shared on an office network?

Yes — the LaserJet 4240N has Ethernet connectivity, so plug it into your network and install the driver on each workstation. Every computer can then send jobs directly to the LaserJet 4240N.

How do I fix smudged toner on prints from the LaserJet 4240N?

Smudges usually mean loose toner dust inside the LaserJet 4240N — printing a few blank pages flushes it through. If smudging continues, check that the cartridge is seated properly in the LaserJet 4240N and not leaking.
