Canon PIXMA TR4665 Home Office Ink Cartridges
Your PIXMA TR4665 Home Office uses the PG-645 / CL-646 cartridge series. This printer utilises a two-cartridge system, consisting of one dedicated pigment black cartridge for crisp text and one tri-colour cartridge for all colour graphics and photos. We have been supplying consumables for this printer since 2021, helping users manage the unique replacement behaviour of integrated printhead cartridges. Because the tri-colour unit houses cyan, magenta, and yellow together, depletion of a single primary colour requires replacing the entire colour cartridge to maintain accurate colour reproduction.
Getting the most out of your cartridge yield
The number of prints you can expect depends heavily on whether you use standard or high-yield XL versions. Canon determines these page yields using the ISO/IEC 24711 international standard for continuous printing on plain A4 paper. For home office users, the XL cartridges are almost always the more logical choice, providing more than double the capacity of the standard versions. This significantly reduces the frequency of cartridge swaps during larger document runs.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| PG-645 | Standard | Black | 180 | $0.14 |
| CL-646 | Standard | Colour | 180 | $0.19 |
| PG-645XL | High Yield | Black | 400 | $0.11 |
| CL-646XL | High Yield | Colour | 400 | $0.11 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Strategic buying for home office use
For those who primarily print text documents with occasional colour logos or charts, the black cartridge will naturally deplete faster. However, purchasing PG-645 and CL-646 bundles is the most effective way to secure a lower price per unit compared to buying them individually. If you find your printer sitting idle for weeks, ensure you run a nozzle check once a month to prevent the ink in the integrated printhead from drying out.

Pro Tip
Since the PIXMA TR4665 uses a tri-colour cartridge, printing photos with heavy saturation in one specific colour (like a blue sky) will exhaust that cartridge faster, even if the other colours are full. To extend the life of your colour ink, use 'Draft' or 'Grayscale' settings for internal documents that don't require professional presentation.
Frequently Asked Questions
Can I install a PG-645XL cartridge if my printer came with a standard PG-645?
Yes, the XL cartridges have the exact same external dimensions as the standard versions. They are designed to fit the same carriage slot in your PIXMA TR4665 but contain a higher volume of ink inside the casing.
Why does my printer show the colour cartridge is low when I only print in black?
Even when printing in black and white, the printer uses a small amount of colour ink for maintenance cycles and to "undercoat" certain shades of grey to improve contrast. Over time, this leads to the colour cartridge needing replacement even without heavy image printing.
What happens if one colour runs out in the CL-646 cartridge?
Because the CL-646 is a tri-colour unit, if any one of the three internal chambers (cyan, magenta, or yellow) is empty, the entire cartridge must be replaced to continue printing accurate colours. The printer cannot pull yellow from another source if the yellow chamber is dry.
