Repair the CSIC contacts

The structure of the CSIC, especially its contacts is different from the previous series and models. Not only in the number of contacts, but also with it’s the shape and size. Contacts for Epson XP are longer, so be careful when inserting and removing the CISS cartridges and the refillable cartridges. 

There have been cases when, due to the careless removing of the cartridges, the plastic ledge that holds the chip in CISS or refillable cartridges wrest the central contact. We recommend cutting this ledge, but if you haven’t done it and you broke the contact on CSIC, then this article is for you.

Here is the ready pad

Figure 1 shows the CSIC, where the 3 contacts are broken.
