If you use the cash register system on a Mac (MacBook, iMac, Mac Pro) in combination with the mPOP cash drawer-bond printer combination, you can check here how to solve any problems.
Prerequisites Checklist
Is the device properly connected to the computer via USB cable?
Check if the USB cable is connected to the correct port on the mPOP drawer:
Only a single blue light should be on at the mPOP device
- If yes: Everything is fine here
- If no light is on: Is the mPOP device connected to power?
- If a red light is on: Is the receipt drawer closed properly? Is the paper empty or incorrectly inserted?
Tip: The receipt drawer can be opened by pressing against it.
Is there a stable internet connection?
- Test: Please open a website that hasn't been opened in a long time.
- If the page doesn't load (or loads very slowly): Check your internet connection.
Restart Satellite
- Right-click on Satellite icon > Exit
- Restart Satellite
Printer is available
- Is the mPOP cash register listed in the Mac's printer settings and available?
- To do this, click on the small magnifying glass (top right in the menu bar) and search for "Printers & Scanners".
- Open your Mac's settings from the suggestions list and check the list of installed printers.
Possible problems and their solutions:
Red light on the mPOP cash register is on: Is the receipt roll empty?
- Is the receipt roll inserted correctly?
- Is the paper empty?
- Solution: Insert a full receipt roll correctly and close the receipt drawer properly.
Tip: The receipt drawer can be opened by pressing against it.
