Printer Keeps Ejecting the Roll Paper
When a sheet is selected on the HOME screen, loading a roll paper with its surface left loose may make the
printer recognize the loaded roll paper as a sheet.
In this case, selecting Remove paper on Paper menu may allow the printer to keep ejecting the paper.
Check the paper feed settings on the printer.
After roll ejection stops, follow these steps to reload the roll.
1. Push release lever back.
2. Using both hands, rotate the roll holder toward the back to rewind the roll.
At this time, ensure that both ends of the roll are rewound evenly.
3. Pull release lever forward.
