LaserJet 4345X

HP's 4345X was an expanded configuration of the LaserJet 4345 multifunction — extra capability for offices whose 2004-era MFP needed to do more. The core print/copy/scan formula stayed the same reliable performer.

It takes the HP 45A cartridge (Q5945A). We carry compatible 45A toner and genuine OEM Q5945A for the 4345X.

Frequently Asked Questions

Which toner cartridge does the LaserJet 4345X use?

The LaserJet 4345X uses the Q5945A toner cartridge. Confirm the code printed on your current cartridge matches before ordering a replacement.

Does the LaserJet 4345X warn me before the toner runs out?

The LaserJet 4345X displays a toner-low or replace-toner message when the cartridge nears empty, so you get advance notice. Keep a spare Q5945A on hand so a deadline job never catches the LaserJet 4345X without toner.

When should I replace the toner cartridge in the LaserJet 4345X?

Replace the cartridge in the LaserJet 4345X when prints stay faded after redistributing the toner, or when the printer reports it empty. Running the LaserJet 4345X on a fully depleted cartridge risks blank pages mid-job.
