Could you send some images before curing and after curing to figure out the problem?
Keep in mind that If you use single color it will be low resolution. You need to use color black printing by this way printer mixes 3 colors to obtain black and get maximum resolution. I don't have R300 but with my CX4200 I am still getting excellent results and I am always using 3 colors.

Now I have tried to make PCBs with it but no success.
I've tried to prepare the pcb with Bora's HCL method, and sandpaper
but seems like the problem isn't this because the results are equally bad.
I tried to cure the ink in an oven, and with a heat gun but again, the
results were equally bad.
After etching, the board shows just a faint image of the layout I
tried to get, almost all the copper is gone and just small dots remain
so that I can see the layout. I etched with a strong ferric chloride.
I don't know if the problem is printing. Because I've heard that the
mispro YELLOW is the best one, I bought a yellow cartridge. At first I
wanted to install that in the black ink position but my printer won't
allow me to do so. So I have to export my design from EAGLE editor as
an image, and I change the color in Paint shop pro to Yellow...
Please help, I really need to get this system working because it
allows so much faster production of PCBs.
