Frequently Asked Questions

Which toner cartridge does the LaserJet 9040 use?

The LaserJet 9040 uses the C8543X toner cartridge. Confirm the code printed on your current cartridge matches before ordering a replacement.

Why is my LaserJet 9040 printing faded or streaky pages?

Faded or streaky output on the LaserJet 9040 usually means the cartridge is running low. Remove the C8543X and gently rock it side to side to redistribute the toner; if fading persists, the LaserJet 9040 needs a fresh cartridge.

How do I clear a ‘Toner Low’ message on the LaserJet 9040?

On the LaserJet 9040, the Toner Low message means the cartridge is nearly empty — you can keep printing for a while, but order a replacement now. Installing a fresh cartridge clears the warning on the LaserJet 9040 automatically.
