Fax/Printer Cartridge

[ss30]

HI last month our fax machine broke so the wife went to argos and pick up a Xerox Office Fax IF 6020 we only use it for sending faxes (we receive faxes on a PC) so all that gets printed from the fax machine is the report after a fax has been sent. It came with a cartridge which is now low on ink and a replacement cartridge is £42.00 I have a look with google to try and find a compatible one but I cant find one, here are a few pics anyone know if it's used by another manufacture.

On the sticker it says "intended for single use only"

Xerox call it IC601




Thanks ss30

EDIT: sorry about the shite pic's
