CANON CLC 10 / BC 40 CARTRIDGE
If the cartridge will only accept 10-15ml. of ink, the ink has not flowed through the internal sponge. The cartridge should be swung through a slow pendulum action with the print head facing down to move the ink towards the nozzles. N.B. Ink may leak from the nozzles. Use absorbent material to prevent spillage.
Note: Empty cartridges should be refilled immediately.
