Lexmark CS714DN colour Laser Printer (with wireless module)

Note this is currently not working so is for Spares or Repair

It has two issues:

1) The rollers were replaced after which I guessing it wasn't put back 100% correctly as when printing in colour the page had a Cyan colour wash over it - Although it printed perfectly fine in B&W

2) Before trying to fix the above issue, the printer firmware was updated, which then locked the printer into using Lexmark "chipped" Toner cartridges. The ones currently in the printer are either non-Lexmark or older Lexmark ones, so it won't allow you to print. Also from what I could find it is not possible to reverted the firmware version.
