Compatible HP 51A Replacement
This LD Products Q7551A cartridge replaces the original HP 51A black laser toner. It is built for offices and home users who need reliable monochrome printing on supported Hewlett Packard printers. The remanufactured unit delivers an economical alternative to OEM supplies without voiding the printer warranty.
Remanufactured Build Quality
Each cartridge is fully disassembled and rebuilt with up to 85 percent new parts including wiper blades and OPC drums. An electronic smart chip provides accurate toner level readout during normal use. The process aims to match or exceed OEM page yield while maintaining consistent print quality.
Drop-In Cartridge Fit
The cartridge installs directly into the printer’s toner bay with no extra hardware or adapters required. It frees up budget compared to original HP cartridges while fitting the same slot and workflow. Buyers who need colour output or a different page yield should look for the appropriate cartridge model.

Questions about this item
How do I install the LD Q7551A cartridge and what step is often missed?
Remove the cartridge from its packaging, pull the sealing tape straight out, then insert it until it clicks; forgetting to remove the tape blocks toner flow.
Which parts will need replacement after extended printing?
The cartridge is rebuilt with up to 85% new parts including wiper blades, OPC drum and smart chip; when toner is depleted the whole unit is replaced.
What limit appears first during continuous high-volume printing?
The page yield matching the original 51A specification is reached first, requiring a new cartridge to continue printing.
