succumbed and bought one, complete with bottles, syringe and my favourite..2 small ball bearings. Please see enclosed instruction sheet, the problem is there isn't one! Could someone please give me some helpful advice? Thank you
Have a look at the site Stratitec.com.
There are plenty of instructions according to either the refill number or the Printer model.
There are pictures and full instructions.
The ball bearings are only required for certain types of cartridges.
Hope this helps.
