HP4005 - Resetting Transfer Kit Count

[Sam_Brown]

We have a HP Laser Jet 4005 which needed a new Transfer Kit. Luckily we had one from an old 4005 which has only been used for about month before the printer died.

 

I thought great... saves having to buy a new one! Stuck the "new" transfer kit into the needy 4005 and noticed that it's still moaning about only having 400 pages before it requires changing. Been through all the menu options and no way to manually reset the figure from what I can see. On further investigation it appears as if only brand new transfer kits will automatically reset the count.

 

Anyone know how to reset the count manually? Google isn't helping.
