Also with me wb-can were delivered instead of LS-CAN. However, this was not to me, I have no idea what it means but the WB can not print correctly in my 5450th Until I have guessed what it is passed weeks. I have the print head cleaned for days because I thought he was constipated, also a new printhead I ordered. All to no avail. Then I read the reviews about incorrect delivery with wb-can and looked at the cartridge carefully and in fact it was the case with me. That would otherwise never occurred to me. Then I made a pure LS-can cartridge and everything worked again. The WB-CAN cartridges I can dispose now probably. I'm pissed off. In a set with all the colors that I have ordered from the same supplier were the LS-CAN it. may be the the WB can work with other printers, the mg5450 they do not.
