MC-G04 MCG04 5813C001 Waste Ink Cartridge Maintenance Kit Compatible for Canon G1230 G2270 G3270 G3272 G4270 Printers, High-Capacity, Pack of 4

Why does it hold so much ink despite its small size?1---The interior isn’t an “empty box,” but a high-density absorbent sponge.The interior is almost entirely composed of compressed, high-density absorbent cotton (composite fiber/porous polyurethane).This sponge has extremely fine pores, extremely high density, and a high compression ratio: When dry, it’s small and very hard. After absorbing ink, it slowly expands, locking in the ink and preventing it from flowing or leaking.Simply put: 1cm³ of dry sponge ≈ can absorb 1–2cm³ of ink.Therefore, a palm-sized box has an effective ink-absorbing volume close to the outer shell volume, naturally justifying its 300ml capacity.2---Structure: Fully sealed + layered flow, no wasted space.Completely sealed shell: No extra cavities; all ink is locked inside the sponge.Multi-layer/honeycomb structure: Ink is injected from the top, evenly penetrating the entire sponge, preventing localized ink buildup and short circuits.Unlike ordinary sponges that “overflow when partially saturated,” its utilization rate is close to 100%.3---The actual amount of waste ink produced by the printer is not much.You might think “300ml is a lot,” but for the printer:Each printhead cleaning: only a few milliliters of waste ink are discharged.Borderless printing: a small amount of waste ink at the edges.Daily document printing: almost no waste ink is produced.The official xxx-page lifespan is calculated based on: Standard document + a small amount of cleaning + a small amount of borderless printing.If you clean the printhead daily and print photos frequently, the lifespan will be noticeably shorter, but 300ml will still last a long time.It doesn’t seem large because the sponge is compact when dry; the high ink capacity comes from high-density sponge that securely holds several times its own volume in ink, avoiding leaks and wasted space.
