I will not use the printer for a long time, how to save the CISS system?

Question

Continuous Ink Supply System

There is an Epson printer with a continuous ink supply system. Who will be without a job for the next six months.
How to properly prepare the printer for such downtime? How to protect CISS from drying out?

Answer 1

The situation is hypothetical for me (since mine turns on at least once a month - to print utility bills), so I will answer speculatively - how I would put the printer into hibernation myself if it were impatient.
1. First of all, I would drain the CISS and rinse with flushing fluid for jets. Which, if you believe what they write on the Web, is ordinary distilled water, and you can get it in commercial quantities from battery workers and doctors.
2. I would fill the entire ink supply path with this very water.
3. To guarantee filling, I would print several pages with this very water (in each color - both in black and in other mono-colors), until the shade of the previous color disappears on paper. Then there will be nothing to dry.
And when removing from suspended animation - in the reverse order, and also print out for testing.

Answer 2

The original ink does not "dry", unlike the compatible ones used in CISS. It is still optimal to use the device at least once a week.
