When the YUMBI Printer displays a "not registered error," it typically indicates a network-related issue preventing the printer from connecting to the network, a condition known as the “printer is not polling.”
During normal operation, the YUMBI Printer will show a signal bar on the left side of the screen. This is accompanied by the letter 'G' and an arrow in the top-left corner, indicating a successful network connection. An example of a fully operational YUMBI GSM Printer is depicted in the image provided below.
It is important to note that several factors could contribute to network issues such as:
- The aerial antenna might not be securely fastened and positioned at a 90-degree angle (adjust according to your printer model).
- Unstable or weak network coverage in the vicinity of the network provider configured on the printer.
- Interruptions such as load shedding.
The networks we configure on the YUMBI printers are MTN and Vodacom. If a store experiences poor network connection with one network, we recommend reconfiguring to the alternative network between the two for better functionality. Should you opt to swap the networks, please complete the following YUMBI PRINTER Fault online form here for assistance. Note: The store will need to determine the optimal network coverage in the area before proceeding with the swap.
