1. Power on the printer and open the ink access door.
2. Wait until the carriage stops moving, then press the tab to release the empty cartridge.
3. Unpack the new cartridge and remove protective tape (avoid touching contacts/nozzles).
4. Insert the cartridge firmly until it clicks, then close the cover.
5. If prompted, run alignment or print a test page to confirm installation.

• WPS method (if supported): Press the Wi-Fi button on the printer, then press WPS on your router within 2 minutes.
• Screen setup: Use Wireless LAN Setup on the printer display, select your network, and enter the password.
• No-screen models: Use Canon setup software/app on your computer/phone and follow the on-screen steps.
• If it fails, restart printer + router and confirm the correct Wi-Fi password and compatible band (often 2.4GHz).

Cartridge series depends on your exact Canon printer model. Use the finder on this page, or check the label inside the cartridge door or your printer manual. Canon typically lists supported cartridge numbers there.

• PG/CL series usually indicates Black + Color cartridge families.
• XL versions (when supported) provide higher yield and better cost per page.

1. Confirm the cartridge series matches your exact Canon model.
2. Remove and reinsert the cartridge until it clicks; ensure all protective tape is fully removed.
3. Power cycle the printer (off, unplug 60 seconds, restart).
4. Gently wipe cartridge contacts with a dry lint-free cloth (no liquids).
5. If it still fails, email support@starinkshop.com with your model and the error message.

• Run a Nozzle Check to see which color/channel is missing.
• Run Cleaning once, then re-test (avoid repeated cycles back-to-back).
• Confirm paper type and print quality settings; verify the correct printer is selected.
• Make sure cartridges are seated correctly and not empty.
• If it continues, try Deep Cleaning once, then contact support with your model.

Refilling may work for some cartridges, but results vary and it can increase the risk of leaks, clogs, and inconsistent output. For a cleaner, repeatable experience, use a compatible replacement that matches your exact Canon model and install it like a standard cartridge.
