True Color 646X 4-Pack for HP CM4540

This four-pack supplies black, cyan, magenta and yellow high-yield toner cartridges that replace OEM numbers CE264X, CF031A, CF032A and CF033A. It is intended for offices running the HP Color LaserJet Enterprise CM4540 MFP series and needing consistent colour output across high-volume print jobs.

Installing the four cartridges

Each cartridge slides into its colour-coded slot until it clicks, requiring no tools or firmware updates. The most common issue is forgetting to pull the sealing tape completely from the drum unit, which leaves a blank stripe on the first few pages; a second issue is inserting a cartridge into the wrong colour position, which the printer will flag immediately.

Checking your printer before ordering

Confirm the machine is a CM4540 MFP variant, because other HP LaserJet models use different cartridge shapes and chip identifiers. Verify the current cartridges show the part numbers CE264X for black and CF031A, CF032A, CF033A for the three colours, and ensure the printer reports no existing supply errors that could prevent recognition of new chips.
