Attention to new print monitors:

If you’re a new print monitor, and don’t know how to switch the paper roll for Epson 7900 and other issues for either Epson 4880 or 7900, you may find the printer manuals in the OP1222 printing room. I will suggest you to read the manuals and practice more to ensure you are capable of switching the paper roll especially. Let me know if you have further questions or problems.
