The issue of voiding warranty as espoused by the OEM is illegal under the Trade Practices Act and so the threat to not fix a fault in the printer when under warranty because the owner has used a remanufactured or compatible cartridge can not be enforced. All products supplied from Ink on the Run are fully guaranteed to perform as well as if not better than the OEM product with at least the same volume of ink/toner as per the OEM specifications.
