This most likely indicates that the printer cover is open, the printer is out of paper, the paper roll is not loaded correctly, or that the cash drawer has failed to open.
- Open the printer cover and remove the paper roll, or reload a new roll if your printer’s paper is running low.
- Reload the paper roll and close the cover. Please ensure that the paper roll is loaded in the correct direction.
- Remove anything that may prevent the cash drawer from opening. In the SwipeSimple app > Settings > Device Management, select your mPOP and Test Cash Drawer.
