Canon imagePROGRAF TC-21 Ink Cartridges
Your imagePROGRAF TC-21 uses the PFI-050 cartridge series. Our 4.8 Google Star rating highlights our commitment to delivering dependable cartridge options coupled with premium print performance. Ink Depot has supported users by supplying consumables for this printer since Jul 2025. The printing architecture incorporates high-capacity individual refill channels for black and colour channels, a setup specifically optimised for handling architectural layouts, line drawings, and bright office posters. Managing individual fluid levels is direct and simple, though the printer naturally draws minute amounts of ink from both housings during routine cleaning cycles to keep the micro-nozzles clear.
Real-world cartridge yield and performance
Expected page delivery depends heavily on the volume of graphic elements, line thickness, and background text density present in your daily print runs. Standard manufacturer test ratings are calculated according to industry standard continuous printing benchmarks for large format inkjet systems, offering a reliable comparison metric based on steady technical illustration workloads rather than dense full-bleed presentation prints.
Evaluating alternative consumable options
Maintaining clear technical documentation layouts is simple when operating with original fluid formulas designed to interact properly with your technical plotting machinery. Under Australian Consumer Law, using certified alternative items does not automatically invalidate your system equipment assurances. Choosing factory original lines guarantees your fluid media maintains correct physical fluid mechanics to preserve proper precision line tracing and long-term storage qualities.

Managing print workloads and ordering setups
Professional design offices handling regular technical administration find that choosing high-volume supply arrangements helps avoid unexpected interruptions during long project deadlines. If your workload involves drafting line blueprints with only minor color callouts, pairing value-pack multi-packs alongside a dedicated black tank ensures your system maintains uninterrupted operational continuity. Genuine manufacturer ink solutions feature stable formulation standards for complete reassurance. Every transaction is processed in accordance with the provisions outlined in our official Returns policy. Free delivery applies on all orders over $99 (conditions apply), with shipments coordinated instantly from our localised distribution hubs in Perth, Brisbane, Sydney, Melbourne and Adelaide.

Pro Tip
Always fill the internal ink reservoirs as soon as the control panel signals a low fluid alert rather than waiting for the tanks to empty completely. Refilling early prevents microscopic air bubbles from entering the sub-ink tank lines, ensuring consistent plotting precision and avoiding accidental printhead alignment issues during critical CAD operations.
Frequently Asked Questions
Are these products plastic cartridges or replacement ink refill bottles?
The PFI-050 series consists of specialised high-capacity ink refill bottles designed to replenish the printer's integrated eco-tank reservoir system. They feature a unique physical key design at the nozzle entry to ensure that each color can only be inserted into its corresponding internal tank port.
Can I mix the different colors from this series together during refilling?
No, each color must be poured exclusively into its designated color-coded slot on the front of the printer. Accidentally mixing ink colors within a single chamber will contaminate the color output and require a comprehensive system flush to restore correct graphical performance.
Why are there no compatible or third-party ink options listed for this model?
Large format technical plotters require precise chemical formulations to ensure line accuracy and prevent the dense printhead arrays from clogging. Currently, only genuine Canon PFI-050 original inks are available to maintain the structural integrity and performance requirements of your imaging equipment.
