Two-pack black toner cartridge

This pack contains two new black toner cartridges built to replace the HP 51A Q7551A original. Each unit is manufactured to meet or exceed the OEM specification and carries a two-year shelf life. The standard-yield formulation is intended for everyday monochrome laser printing in compatible HP LaserJet Pro and P3005 series devices.

Suited for high-volume mono printing.

Offices and workgroups that run HP LaserJet Pro MFP M3027, 3027x, 3035, 3035xs, P3005, P3005dn, P3005n or P3005x printers will find a direct drop-in replacement. Buyers who need colour output, require a different page-yield tier, or operate printers outside the listed model range should look at other supplies.

Standard-yield page count determines cost per page

The cartridges are rated at standard yield, so the total number of printable pages per unit sets the ongoing cost for each print job. Users who print larger monthly volumes may prefer a higher-yield alternative to reduce replacement frequency, while lighter users will match the standard yield to their needs.

Questions about this item

What is included in the 2 pack and do I need to buy anything else?

The box contains two new black toner cartridges. Each unit is a complete replacement for HP 51A Q7551A. No extra parts or bottles are required.

Both cartridges are labelled Standard Yield — is there a high-yield version in this listing?

This listing only includes the Standard Yield version. Both cartridges in the 2 pack share the same yield rating.

What does Standard Yield mean for page output in my HP LaserJet P3005?

Standard Yield matches the original HP 51A rating. Actual page count varies with coverage, but the cartridge is designed to meet that benchmark.
