Yesterday, in the middle of printing, the l1800 stopped printing red.
Now I immediately tried the standard things, to clean the head,
blow out the dumpers, in the end, I replaced the dumpers and the head,
I changed the paint and the bottle where the paint was, I checked the flat cables ..


I have no more ideas, everything looks normal but there is no red.
I even replaced the computer, USB cable, and drivers.

Any ideas?

Checking is not enough. Cracked ribbon cables are tricky.
It could also be the mainboard.

Thanks, I will buy a new MB and new cabel and try. Thanks

I change MB and flat cable, and I think maybe its cap, is it possible? The same thing with all new parts, and i think that the last option is cap i change all other things..?
