Hallo again,
A question!
Those with new printers like 9000 Epson series - if you
look very close to the tubes - it's very tiny, and hard to find.
Can You see any "type number" or brand on them!
If on those printers they must be good - however bending flexibility
might be different - and the main last support may be modified.
Simple done with a thin plate of aluminium that is cut out and bended,
and fixed to hold the tubeset free!
Made three CFS's myself - the weak link is the tubes! Cheap things!
both on MIS and CIS version of CFS-systems!
(I know what it is! Water permeable and used for short term in
hospitals and universities!)
For those interested have a look here!
Alcohol at least seems to be one ingredient:

Fiat Lux!
