Package contents

• 1 × Plutoos 337XL Ink Cartridge Black · 18 ml · up to 550 pages · OEM ref. C9364EE

Installation & first use

1. Unpack only right before installing and pull the protective strip.
2. Insert until it clicks — the cartridge is recognized automatically, no resetter needed.
3. Confirm the “non-genuine cartridge” notice with OK — this is normal.
4. Print a nozzle check after installation.

Care & storage

• Store sealed, upright, at 5–35 °C, away from direct sunlight — best used within 24 months.
• Print a few pages at least every 2–3 weeks so the nozzles do not dry out.
• Never leave the printer without a cartridge — the print head can dry out.
• Storing an opened cartridge: seal all open ports with the original protective tape, a tank tape or ordinary scotch tape, cover the contacts, store upright at room temperature.
• (Our advice: once opened, use the cartridge up completely rather than storing it — opened cartridges are very likely to dry out or start leaking.)
• Recycling: Return empty cartridges to us free of charge, drop them at any electronics store (e.g. Media Markt, Fust or Interdiscount) or hand them in at a recycling centre.

Good to know

• “Non-genuine cartridge” message: One-time notice — confirm with OK, printing continues normally. The printer warranty remains valid.
• Firmware updates:Printer manufacturers occasionally release updates that restrict the recognition of non-original cartridges — as a rule, only the latest firmware versions are able to identify and block compatible cartridges. Many customers and user forums report that those who want to use compatible cartridges improve their chances of trouble-free operation when automatic firmware updates remain switched off in the printer settings. If an update has already been installed and messages such as “Cartridge not compatible” or “Ink level low” appear, other customers report that rolling the firmware back to the previous version has helped — instructions can be found via a Google/YouTube search for your printer model and “firmware downgrade”. We pass on these experiences of other customers in good faith; whether and how you apply them is solely your decision and responsibility — results may vary from printer to printer.
• Ink level display: The printer reports ink levels; on some models the display may differ slightly — the actual fill volume is not affected.
