The Canon PFI-3700 Blue Ink is a genuine 700 ml LUCIA PRO II pigment ink tank for the Canon imagePROGRAF PRO-2600, PRO-4600 and PRO-6600, as well as the GP-2600S, GP-4600S and GP-6600S large format printers.
Blue is one of the extra colours in the LUCIA PRO II set, helping these printers reproduce deep blues and violets that are hard to achieve with cyan and magenta alone. The 700 ml capacity means fewer tank changes on long runs.

Why choose the genuine Canon PFI-3700 Blue Ink?
What sets apart a genuine Canon PFI-3700 compared with a refilled or copied cartridge:
- Accurate, consistent colour. Genuine Canon inks are formulated for imagePROGRAF colour profiles and print heads.
- Long-lasting prints. Canon’s inks are designed for durable output on the media your printer supports.
- Protects the print head. Filtered Canon ink helps prevent nozzle clogs on expensive print heads.
- Reliable ink tracking. The printer reads genuine tanks accurately, so you know when to reorder.
It suits print shops, studios and photo labs running an imagePROGRAF PRO or GP series printer at high volume.

- Wait for the printer to confirm the new tank before continuing to print.

Troubleshooting tips
If the Canon PFI-3700 Blue Ink isn’t printing as expected after installation, these quick checks solve most problems:
- Tank not recognised: Re-seat the tank firmly and make sure it’s in the correct colour slot.
- Colour looks faint: Run a nozzle check and, if needed, a cleaning cycle.
- Ink level shows incorrectly: Close the cover fully and leave the printer on so it can read the new tank.
Looking after your printer between cartridge changes
- Shake new ink tanks gently before installing, as Canon recommends for pigment inks.
- Keep the printer switched on standby so automatic nozzle maintenance runs.
- Replace empty tanks promptly to avoid air entering the ink system.
- Run nozzle checks before long or important jobs.
- Keep spare tanks stored at room temperature away from sunlight.
Storage, handling and recycling
To keep a spare Canon PFI-3700 Blue Ink in top condition until you need it:
- Keep it sealed. Leave the tank in its packaging until needed.
- Store at room temperature. Avoid heat, frost and direct sunlight.
- Use before the date. Install before the date printed on the box.
- Recycle the empty. Return empty tanks via Cartridges 4 Planet Ark.
Canon Australia supports free cartridge recycling through Cartridges 4 Planet Ark, so your empty PFI-3700 can be dropped at a participating store instead of going to landfill. For full product information, visit Canon Australia.
Genuine vs compatible cartridges
Compatible cartridges can cost less up front, but quality varies a lot between brands. The Canon PFI-3700 Blue Ink is made by Canon for these printers, is covered by Canon’s manufacturer warranty against defects, in addition to your rights under Australian Consumer Law, and is designed to deliver its rated yield. Our article on OEM vs compatible printer cartridges compares the two in more detail.
Every cartridge we sell under the Genuine label is brand new and sealed in Canon retail packaging. If you’re ever unsure whether a cartridge is authentic, check the box for Canon’s security label and an intact factory seal, and buy from a supplier that lists the Canon part number.

Canon PFI-3700 Blue Ink FAQs
Is this Canon PFI-3700 Blue Ink genuine Canon?
Yes. It’s a brand-new, genuine Canon cartridge supplied in sealed Canon retail packaging, not a compatible or remanufactured product.
How many pages does the PFI-3700 print?
It holds 700 ml of ink. The number of pages depends on what you print and your print settings.
Which printers use the PFI-3700?
It suits the Canon imagePROGRAF GP-2600S, Canon imagePROGRAF GP-4600S, Canon imagePROGRAF GP-6600S and 3 more models. Check the full compatibility list above before ordering.
What is the Canon part number?
Look for the code PFI-3700 on the cartridge label or box.
How much does delivery cost?
Delivery is a flat $19.99 per order within Australia, no matter how many items you buy, and generally arrives 3–7 business days after dispatch.
Do you deliver to regional and remote areas?
Yes. We ship to every Australian state and territory at the same flat rate. Remote addresses can take a little longer. We don’t currently ship internationally.
Will I get tracking?
Yes. Tracking details are emailed to you once your order is dispatched, where the courier provides them.
Can I return it if I change my mind?
Yes, let us know within 30 days of delivery. The cartridge needs to be unopened and unused, and change-of-mind return shipping is paid by the customer. Approved refunds are processed within 7 business days.
What if my PFI-3700 is faulty?
Contact us with your order number and a short description of the problem, plus photos if you can. We cover return shipping for faulty products and will arrange a replacement or refund in line with Australian Consumer Law.
Can I replace the PFI-3700 while printing?
Many imagePROGRAF models allow hot-swapping ink tanks during a job. Check your printer’s manual for its exact procedure.
Should I shake the ink tank?
Gently shake pigment ink tanks a few times before installing so the ink is evenly mixed.
How long does an ink tank last once installed?
It depends on print volume and coverage. Canon recommends using ink within the period printed on the box.
Do I need every colour installed to print?
Yes. imagePROGRAF printers need all ink tanks installed to print, so replace an empty tank as soon as the printer asks for it. Keeping a spare of your most-used colours avoids downtime.
What does the ml capacity mean for my printing?
The capacity tells you how much ink is in the tank. How many prints you get depends on the media, print quality setting and how much of each page is covered, so large photographic prints use far more ink than line drawings.
