Step-by-Step Replacement Instructions
When the printer’s LCD screen notifies you that the maintenance cartridge is full, follow these steps to replace it:
-
- Preparation: Ensure the printer is powered off.
- Access: Use a coin to loosen and remove the screw from the maintenance cover on the printer
- Removal: Put your finger in the hole of the cover to remove it, then pull out the old maintenance cartridge until it stops. Lift it slightly and pull it all the way out.
- Disposal: Immediately place the used cartridge into the plastic bag provided with the new unit. Seal it tightly and keep it level to prevent ink leaks.
- Installation: Slide the new MC-G03 maintenance cartridge straight into the slot until it stops firmly.Â
- Secure: Reattach the maintenance cover, align its tabs, and tighten the coin screw clockwise to secure it.
Comparison: MC-G03 vs. MC-G04
While both serve similar functions, they are designed for different printer lines:
- MC-G03: Specifically for the MAXIFY MegaTank line (e.g., GX3020, GX4020).
- MC-G04: Targeted toward PIXMA MegaTank G-series printers, such as the G1230, G2270, and G3270. (Note: You previously purchased a Canon Pixma G2430, which specifically requires the MC-G04 cartridge rather than the MC-G0
