HP Black Plain Paper Print Cartridge

LegacyBlack~750,000 characters3 ml

HP 51604A is the HP Black Plain Paper Print Cartridge, rated at ~750,000 characters (HP approximate character count) — for owners keeping a legacy HP printer in service.

 

Before you order: HP no longer publishes a printer list for this legacy cartridge. Send us your printer model before ordering and we will confirm it takes 51604A.

What's in the Box

  • 1 x HP Black Plain Paper Print Cartridge (51604A) in HP retail packaging
  • Cartridge only — other colours and printer accessories are sold separately

What It Means in Practice

  • ~750,000 characters is the HP rated average (HP approximate character count). Pages with photos, large colour areas or frequent single-page jobs use more ink, so real-world yield varies.
  • 3 ml of ink.
  • Installation: open the cartridge door, wait for the carriage to stop, unclip the old cartridge, remove the protective tape from the new one and click it in. The printer may run a short alignment.
  • Genuine HP supply: the printer recognises it and does not show non-original supply warnings.

What Will Not Work

  • Printers not listed here that use a different cartridge number — 51604A is a 96-dpi plain-paper cartridge; later HP cartridges such as 51626A or 51629A use different heads and are not interchangeable.
  • It does not print colour — this is a black-only cartridge.

Frequently Asked Questions

Will I really get about 750,000 characters?
That figure is the HP average under a standard test pattern. Text-only pages usually do better, photos and full-colour pages worse. Printing often also helps, because the printer uses ink for maintenance when it sits idle.
How do I know this is the right cartridge?
Check the number on your current cartridge or on the label inside the cartridge door — it must say 51604A. If the number is different, this cartridge will not fit.
Singular Expert Insight · Buyer's Guide
Most problems with ink orders are simply the wrong number: 51604A is a 96-dpi plain-paper cartridge; later HP cartridges such as 51626A or 51629A use different heads and are not interchangeable. Match the number on your old cartridge first, then choose capacity by how much you print. You can compare all original ink cartridges and bottles in our catalogue.
✓ Buy it if your printer takes 51604A cartridges — for example legacy 96-dpi HP thermal inkjet printers.
✕ Skip it if your printer uses a different number, or was bought outside Europe.
→ Also consider a current HP printer if yours is out of support — we can suggest one with low running cost.
Not sure which cartridge your printer takes? Send us the printer model (on the front panel or the label under the scanner lid) and we will confirm before you order.
