This has been a problem since first purchasing my Mutoh Falcon Outdoor (48") in August 2005. Nobody can diagnosis this.
What is happening is throughout most of my prints, not all but mostly ones with saturation of one color like green, purple, blue, I get a small block or large block of fade/dark of that one color that is usually 1-2 inches or 6-8 inches in width. It will do this fading in the same spot in certain files and nothing I do corrects it.
Sometimes the block is darker or lighter of that color. For example, In the one attached photo below it is a print of a palm tree with dark green on top. Every time I print this one particular file I will get the same results..the dark green then it goes into a lighter green then an even lighter green in a pattern just like that. It is like this each time I print it. It is not all images or files though. I can take numerous files and print them all at once and only one of those images will have fading in it. Everything else around it is fine. In the other example photo this is a print with a light green. Each time I print this file I get a 6 inch band of a dark green. Only in one spot on the print does this happen and each time. Then there are other prints I can do that have the opposite, a white fade on it in the same manner, not a dark color.
The third photo is of a red hat and on the top of the purple feather is an example of the color (dark purple) going into a fade (lighter purple).
I have done the following to help correct this:
New print heads, dampers, maintance station. I've tried different media, profiles, computer, files, all sorts of heater settings. I've moved the printer from room to room all different environments with no change. Another printer was nice enough to take one of my files and test it and they didn't get the same results so it is not a file issue.
Any ideas?
maybe a bad heater, media feed motor?? I think it's something mechanical with the printer. But need to find out what exactly. Thanks.
