I changed my ink cartridges in my printer. Did the alignment. Then printed something and it printed ok. Now I have a cartridge error #1203 and it says to check manual but I don't have a manual and I can't find it when I check online. My question is what is this error? I now can't use my printer at all. I checked the cartridges again. Turn off printer remove cartridges and installed again. Still have that error message #1203. Please explain what to do next and what the message means. Thanks!
