Here is a few questions for my epson 3880 pro
1- Can I extend the expiration date of the inks if the bottles are not opened, and kept in a cool place in the dark ? If so for how long ? Please list problems using inks after expiration date.
2- How do you clean your syringe and needle after filling a cart for the next filling time ( greater than 4 months), in order to avoid contamination or clogging ?
3- The same two questions for Thrift Inks
