6180 prints repeating lines of every color on whole page 1 1/8" between same color
This 6180 was not used for quite a while because it was out of black. I bought a black cartridge and it started working, sort of. It prints horizontal lines of each color in a repeating pattern. They are about 1 1/8" between same color. See attached.
I am thinking transfer unit, but wanted to ask before investing so much.
