Epson TM-m30 Technical Reference Manual page 51

Amount of top margin by backfeed
• 2.0mm (initial settings)
• 9.5mm (no backfeed) (initial settings)
• Remove all ejected paper before printing with backfeed.
• Disable the automatic top logo setting when enabling backfeed.
• Backfeed is not performed during the self-test, even if you have enabled backfeed.
• If setting a top margin of 5 mm {0.2"} or less, confirm that no errors occur in your environment of
usage. Usage in a hot and humid environment or usage of paper that curls easily may increase
the risk of paper jams.
• When implementing a backfeed, rubbing smears may occur due to slack in the paper. We
recommend using thermal paper with high rub resistance.
• You can specify values in 0.5mm steps if you use TM-m30 Utility or TM Utility for iOS/Android.
