https://community.usa.canon.com/t5/Office-Printers/Canon-137-cartridge-roller-exposed/m-p/601400#M31224 <P>I just bought a new OEM Canon 137 cartridge, and the blue roller is exposed. On all my previous ones, the roller was covered by a plastic flap. I looked at two other new cartridges and found their rollers exposed, too. Are these all defective, or is that a design change?</P><P>Thanks!</P><P>&nbsp;</P> Tue, 07 Jul 2026 18:40:34 GMT vknowles 2026-07-07T18:40:34Z https://community.usa.canon.com/t5/Office-Printers/Canon-137-cartridge-roller-exposed/m-p/601400#M31224 <P>I just bought a new OEM Canon 137 cartridge, and the blue roller is exposed.
