Finding the right cartridge is straightforward once you know where to look.
Step 1: Find Your Model Number
- Front panel or inside front cover
- Label on back or bottom
- Print a configuration page
- Check computer printer settings
Write down the FULL model number including suffixes. "HP LaserJet Pro M404dn" — the "dn" matters.
Step 2: Cartridge Numbering Systems
HP
CF258A (standard) or CF258X (high yield). A=standard, X=high yield.
Brother
TN-760 (high yield), TN-730 (standard). Drums (DR-730) are separate parts.
Canon
Canon 055 (standard), 055H (high yield).
Lexmark
Complex numbering — search by printer model instead.
Step 3: Verify Compatibility
- Check the cartridge currently in your printer
- Use supplier compatibility search
- Cross-reference cartridge number and printer model
Common Mistakes
- Confusing toner with drum units (Brother/Lexmark)
- Ignoring CMYK color designations
- Mixing up similar model numbers
When in doubt, contact your supplier with your printer model. A good supplier confirms the exact cartridge.
Color Printers
- Black runs out 2-3x faster than colors
- Multipacks save money for full sets
- You can mix remanufactured and OEM in the same printer
Remanufactured Alternatives
Same part numbers as OEM — direct replacements, no adapters needed.
