Question:
Are Canon 275 and 276 standard cartridges the same in volume as the 275XL and 276XL? If I’m refilling them, can I put the same amount of ink in both versions?
Answer:
Canon 275 vs. 275XL: Physical Dimensions vs. Ink Capacity
At first glance, Canon’s 275/276 standard cartridges and the 275XL/276XL variants appear identical—and in fact, they are the same size physically. They both fit interchangeably into your Canon TR4722 or similar models. However, the key difference lies in the amount of ink pre-filled at the factory and the size of the internal sponge.
Standard Cartridges (275/276):
-
Contain less ink (typically around 4–6 mL).
-
Have a smaller sponge that limits the amount of refillable ink.
-
Intended for light or occasional use.
XL Cartridges (275XL/276XL):
-
Come pre-filled with more ink (usually around 8–12 mL).
-
Use a larger sponge, allowing them to hold a higher ink volume.
-
Designed for extended use with fewer replacements or refills.
Refiller's Perspective: How Much Ink Can You Add?
From a refiller’s point of view, you can fill a standard cartridge with as much ink as it can physically hold, but you’lponge size. Ove quickly limits your optionsrfilling a standard sponge can cause leaks, poor flow, or internal pressure issues.
If your goal is to extend refill intervals, you have two effective upgrade options:
Option 1: Larger Sponge Upgrade
You can convert a standard 275 or 276 cartridge into a higher-capacity version by replacing its smaller sponge with a larger sponge, similar to what’s found in XL models.
We offer a modification kit that includes appropriately sized sponges and tools:

This lets you safely increase the ink volume and helps reduce how frequently you need to refill.
Option 2: Spongeless Conversion with Pressure Regulation
Consider removing the sponge altogether and installing a spongeless pressure-regulated cap for an even more reliable and high-capacity setup. This design removes the limitations of sponge absorption and provides:
-
More consistent ink delivery.
-
Better protection against leakage.
-
Easier refilling with syringes or funnels.
We carry a spongeless modification kit that fits Canon cartridges, including the 275/276 series:

Wear and Tear Consideration: Why More Ink Means Longer Cartridge Life
One significant advantage of modifying your cartridge to hold more ink—whether through a sponge upgrade or spongeless setup—is reducing the number of times you need to remove and reinstall the cartridge. Each removal cycle wears down the nozzle contact point and chip interface, reducing print quality or cartridge-recognition errors over time.
