Wolfgray Compatible Ink Cartridges — 4-Pack (934XL Black + 935XL Cyan, Magenta, Yellow) | Replacement for Use in OfficeJet 6220, 6800, 6812, 6815, 6820, 6822, 6825, OfficeJet Pro 6230, 6830, 6835, 6836

Brand: Wolfgray. Not manufactured by, endorsed by, or affiliated with HP. Wolfgray is an independent manufacturer of compatible replacement ink cartridges. The cartridge reference numbers (934XL, 935XL) and printer model numbers listed below are used solely to identify which printers these cartridges are designed to fit. Wolfgray cartridges are third-party products made to the same physical and ink specification as the original cartridge slot they replace.

This is a 4-cartridge multipack: 1 × 934XL Black + 1 × 935XL Cyan + 1 × 935XL Magenta + 1 × 935XL Yellow. XL cartridges contain more ink than standard-yield cartridges and are rated for a higher page yield per cartridge, reducing the cost per page and the frequency of replacement. At £9.99 for a full 4-colour BCMY set, these are positioned as a cost-effective alternative to purchasing four separate OEM cartridges.

Page Yield (Wolfgray-Stated, at 5% Coverage)

• Black (934XL replacement): up to 1,250 pages
• Colour (935XL replacements, each): up to 850 pages per cartridge

Page yields are stated by Wolfgray based on printing at 5% page coverage on A4/Letter paper — a standard industry testing condition. Actual yield will vary depending on print content, settings, coverage percentage and usage patterns.

Important Notices

• Not manufactured by HP. Wolfgray is the manufacturer. The cartridge reference numbers and printer model names are used for compatibility identification only.
• Using a compatible cartridge does not void your printer warranty under UK and EU consumer rights legislation (Block Exemption Regulation); a manufacturer cannot require you to use only their own-brand consumables as a condition of warranty.
• Some printers display a “non-original cartridge” notice when a compatible cartridge is installed; this is a firmware message and does not indicate a fault with the cartridge; accept the prompt to continue printing.
• Store unused cartridges in a cool, dry place away from direct sunlight; do not remove the protective cap until ready to install.
