I have been into sign making for 35 years. From the paint brush to vinyl & just now, large format printing. Just when I was about to figure it out, the rules got changed. I am a one man shop. I am very grateful for this forum. I found it trying to figure out my used Mutoh 1604. Menus & error codes, Oh My! I found answers here. That's why I am here. I hope to be of help to others, if you don't mind old technolgy. Glad to be here & thank-you.
