Canon G3660 MegaTank Ink Bottles
Your PIXMA G3660 MegaTank uses the GI-61 ink bottles along with MC-G02 maintenance cartridges. Ink Depot has been supplying reliable consumables for this printer since Aug 2022. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance. This refillable printer handles high-volume home office tasks efficiently. Document-heavy output depletes GI-61PGBK pigment black ink faster, while graphic jobs draw evenly from GI-61C, GI-61M, and GI-61Y colour supplies.
Expected Page Output and Refill Cycles
Canon tests page yields under the ISO/IEC 24712 pattern for ink bottle systems. Because MegaTank reservoirs hold large fluid volumes, refill cycles occur far less frequently than standard cartridge replacements, maintaining steady output quality across extended document and photo printing sessions.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| GI-61PGBK | Standard | Black | 6,000 | $0.003 |
| GI-61C | Standard | Cyan | 7,700 | $0.002 |
| GI-61M | Standard | Magenta | 7,700 | $0.002 |

Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Choosing Between Genuine and Compatible Options
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Standard compatible bottles provide significant savings while maintaining high page yields and rich print contrast. Read our blog comparing genuine and compatible options to determine which bottle type suits your printing requirements.
MC-G02 Maintenance Cartridge Requirements
The MC-G02 maintenance cartridge is a separate consumable designed to absorb waste ink generated during automatic printhead cleaning cycles and borderless photo printing. Replacing this unit when prompted prevents internal ink overflow and keeps your printer functioning smoothly.

Pro Tip
Always inspect your printer's physical clear ink windows before topping up ink reservoirs, as filling a chamber past the upper fill line can lead to pressure imbalances inside the printhead assembly.
Frequently Asked Questions
Can I top up GI-61 ink reservoirs before they are completely empty?
Yes, you can top up the GI-61 ink tanks at any time. The nozzle tops are designed to fit securely onto the correct colour reservoir and stop automatically once filled, preventing accidental overfilling.
Can I mix genuine Canon GI-61 ink bottles with compatible GI-61 bottles in the printer?
Yes, compatible GI-61 ink formulations are designed to blend seamlessly with genuine ink inside the tanks. However, switching fully to a single brand type per colour channel ensures consistent tone and archival durability.
How do I know when the MC-G02 maintenance cartridge needs replacement?
The printer screen alerts you when the MC-G02 maintenance unit is nearly full. It is best to purchase a replacement promptly so high-volume print jobs are not halted unexpectedly when the unit reaches full capacity.
