Hello, my name is Tarina and I live in Gothenburg, NE. I am trrying to help my mom fix her printer. We currently have been having problems with our Roland and the print looks like its streaks through in our prints, we always make sure our heads our clean and have had no problems until now. We have changed the calibration, scraper, wipers and we're getting ready to change the caps. If this doesn't work we are leaning towards changing the head. I have concerns on how to take it out and install the new one. Any ideas or help would be great! Thank you
