Peel off labels within15mm from the end of the media and set the end emerging 10mm from
the cutter. This prevents the label from sticking inside of the printer.

Receipt paper with black mark
Recommend designing black marks on the receipt as shown in below.
No gap type continuous label should use the same design.
・
If PCS of black marks is less than 0.9, black marks are not sensed and the page
might be skipped or the right length not detected. It causes the failure of sensing.
・
Prohibit pre-printing in the area designated for black marks.
・ There is a feed tolerance ±2% between calculated value and actual length.
Please take into account this tolerance when pre-printed paper is used.
※
The position of black mark is decided by that of black mark.
※
When 58mm
