Process of replacing the printhead

When the printhead is broken, you have to replace it as followings:

1. Take the cartridges out of the carriage unit as the picture shows.

2. Take off the plastic flake which covers the flat cables, there are 2 buckles, you have to separate them from the carriage. Do the same to the other end and take off it.

3. Separeate the flat cable which is inserted into the slot with the chip touches from the carriage with a cylindrical toll

Please note: Be careful of the chip contacts on the flat cable, make sure they would not come off or be removed.

4. Prepare a tool made of hard iron wire like the picture

5. Loose both left and right buckles with the iron toll and then take our the chip contact.
