This is a teardown of the Epson Stylus 820 Photo color printer.

-
-
-
The main stepper motor, the part most likely to fail, is easy to remove.
-
The ink cartridges are easily replaceable.
-
Many parts inside the printer have ink on them, making repairs messy.
-
The other stepper motor is very hard to access and requires disassembling most of the printer.
-
The midframe, which contains the gearbox and secondary stepper motor, is attached to the case with blobs of melted plastic that must be cut off to remove.
-
The case is very hard and tedious to open without breaking tabs.
-
-
-
Bonus Teardown Time!
-
Time to see what is underneath the 'Do not remove' sticker located on the ink cartridge.
-
What is this network of labyrinthine passageways?
-
The answer is a capillary tunnel to reduce ink pressure. The lower row of holes leads into the cartridge itself, while the top row leads to the ink nozzles.
