Here I'll post step by step modification on my Epson S22/T22 to a PCB printer.
Below is a Epson S22/T22:
Taking bits apart:
Power Module off:
Pull the pins/plug off the board, then pull the power module out.
I put 2 washers under each point where the screws are, to raise the X-rail or the head rail, 1 washer = 1.04mm...
I got an error and my guess was that I raised the rail a bit too high, so I changed the washers to a thinner one, 1 washer = 0.75mm. Some people would raise the printer Head rest mechanism the same height as the washers, but I'm not doing that.
Just few minutes ago I was trying out Epson printing options to get the best result of black ink on to the copper clad board, started by choosing Quality option---> photo the paper option--->Epson Photo--->print, then back to paper option--> Epson Glossy-->print and so on. The one that I prefer the most were Photo + plain paper, before printing I use a piece of sand paper fine grade and sand it over the copper clad so that the ink stick better, see the result:

Adding Aluminium railings for PCB feed.
I used glue gun to hold the left rail to the printer housing, is faster.
Now build the right rail, this rail is not glued on to the housing.
Here is the dimension of the rails:
