Margins are wide
Check 1 Is auto cut being used on printed material with a wide margin on the trailing
edge only?
Rolls are advanced a specific amount before cutting to prevent problems with cutting and paper ejection.
This operation is normal.
Check 2 Is leading edge detection set to Do not detect ?
Do not detect may have been set by responding to the message Do you want to set to detect the leading
edge of the paper? when Cutting mode was set to User cut in the touch screen menu.
If the message Do you want to set to detect the leading edge of the paper? appears when setting Cutting
mode to User cut , select Detect (recommended) .
Please note that if Detect (recommended) is selected and the paper has a strong curl, the Print head may rub
against the edge of the paper when printing starts.
