Xerox 8265 Ink Chip
Since two different cartridges of different colors are not working, it’s unlikely that the problem is due to the cards. However, there is one more thing that you might want to check, and that is the position of the cards.
Make sure that your card is placed at the correct distance from the edges of the cartridge as shown in this picture:
Furthermore, in case the card is too thin and is not touching the card reader, try elevating the card by stuffing paper under it to raise it by up to 3mm. This will make sure that the card makes sufficient contact with the reader.
If this still does not work, see if you have any used cartridges bought from us previously. When you insert the used cartridge, it should display “Nearing End of Ink”. However if it still displays the “Not Original Ink” message you currently have, then it means something is wrong with your card reader.
If you follow these steps and the problem persists, it most likely lies within your card reader and not the cartridges.
