Canon PIXMA G3675 MegaTank Ink Bottles
Your PIXMA G3675 MegaTank uses the GI-61 ink bottles. Ink Depot has been supporting high-volume home printers with reliable consumables since Oct 2023. This continuous ink supply system relies on separate ultra-high-capacity bottles for each colour channel, plus a user-replaceable maintenance cartridge. Because the pigment black and dye colour inks deplete at vastly different intervals depending on document composition, monitoring actual liquid levels visually prevents internal printhead starvation. Purchasing bundled multipacks ensures you have replenishment bottles ready, keeping your running costs down to fractions of a cent per page.
Page yield expectations and real-world usage
Genuine GI-61 ink bottles deliver exceptionally high page outputs, benchmarked by Canon using the international ISO/IEC 24712 pattern for continuous color inkjet printing. Black ink bottles yield up to 6000 pages, while individual cyan, magenta, and yellow bottles provide roughly 7700 pages each under standardised test conditions.
| 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 |
| GI-61Y | Standard | Yellow | 7,700 | $0.002 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Managing other printer consumables
Unlike older desktop printers, this MegaTank printer features a user-replaceable MC-G04 maintenance kit. This waste ink box collects excess fluid from automated printhead cleaning cycles and borderless border printing. Keeping a spare maintenance cartridge prevents your printer from locking up during urgent print jobs when the absorbent pads saturate.
Experience Tip: When replacing the MC-G04 maintenance box, ensure the printer is switched on so the internal counter resets correctly when the new unit clicks into place.
Stocking up and delivery options
If your daily print volume heavily favors black text documents, securing extra pigment black bottles is sensible. For colorful graphics and creative projects, complete ink bundles offer a protective backup against uneven colour depletion. We ship your printing supplies directly from five capital city warehouses located across Melbourne, Brisbane, Sydney, Perth, and Adelaide to ensure prompt delivery times. Free delivery applies on all orders over $99 (conditions apply). All purchases remain fully protected by our standard return policies, which you can read in detail on our dedicated returns policy page. For users operating different models across an office setup, exploring our complete Canon ink cartridges catalog helps find corresponding genuine consumables.
Pro Tip
Never rely solely on software prompts for ink monitoring with this continuous ink supply system; visually inspect the front-facing tank windows frequently to prevent air from entering the printhead lines.
Frequently Asked Questions
Can I mix third-party inks into the GI-61 ink reservoirs?
Mixing different formulations inside continuous ink tanks alters fluid density and viscosity, which frequently leads to printhead clogging or color contamination that is difficult to purge. Stick to genuine GI-61 bottles to safeguard the thermal printhead.
Why does the MC-G04 maintenance kit fill up even if I rarely print borderless photos?
Every time the printer initiates a printhead cleaning cycle to clear microscopic nozzle blockages, it pumps ink through the system into the maintenance kit. Regular printhead maintenance contributes directly to the saturation of the waste box.
What happens if the ink levels fall below the lower line on the tanks?
Allowing the liquid level to drop below the physical minimum line risks drawing air bubbles into the ink supply tubes. This disrupts internal pressure and causes irregular ink delivery, requiring a heavy ink flush to rectify.
