I have an IBM Infoprint printer that is working fine - but on the front panel of it, it says "ITU Life Warning". When i open a web browser and go to its IP address - I can select an option to see Supplies Status - this shows the status of the colour cartridges. At the bottom of this list it also has an item called ITU and it looks empty. To the right of it it says "Life Warning".
I have looked on the IBM website and googled it but I cant find out what ITU stands for!
We have a service contract with IBM - but I dont want to call it in if it just means pressing a button somewhere to get it sorted.
Thanks for your help.
