[Sonic Mini] Checking the Touch Panel

If you're experiencing issues with the touch panel on your Sonic Mini, such as unresponsiveness or erratic behavior, don't worry, there are some steps you can take to see if the issue is simply a loose or poorly connected. This can happen if the pins of the cable have become loose or shifted out of place.

In this guide, we'll walk you through the process of reseating the cable and updating the latest firmware to avoid common touch panel-related issues and keep your printer running smoothly.

1. Checking touch panel cable

One of the first things to check is the touch panel ribbon cable, which may have become loose or disconnected over time.

Power Down and Prepare

• Turn off your printer and unplug it from the power source
• Carefully lay the printer down on a flat surface 
• Loosen the 4 screws on the bottom case, and then open the case

Identify the touch panel ribbon cable connecting the touch panel to the mainboard

• Locate the ribbon cable clip on the mainboard

Reseatting the Ribbon Cable

• Open the cable clip on the mainboard
• Detach the ribbon cable
• Insert the cable all the way into the connector
• Once the cable is fully inserted, lock the cable clip to secure the cable in place

Install the bottom case securely

• Install the bottom case to the printer and ensure it is securely in place

Turn on the printer and confirm proper functionality.

• Plug in the power cord and switch on the printer.
• Check if the touch panel is functioning normally.

2. Updating the Firmware

Reflashing the firmware can solve touch panel issues caused by outdated software conflicts

By doing so, you can make sure the printer's software is fully compatible with the touch panel, which can help to prevent issues such as unresponsiveness or erratic behavior.

Download the firmware to USB drive

• Download the latest firmware version for your Sonic Mini from Phrozen Help Center
• Format a USB to FAT32 and set the allocation to 2048 bytes ( USB 2.0 with 8GB or 16GB is suggested)
• Select a firmware file for your model from the table below, download and unzip the file
• Save all files in the root folder of the formatted USB

Upload the firmware to the printer

• Insert the USB drive into the printer and turn it on
• Printer will automatically update files

Complete the update

• Once the update is complete, unplug the USB drive and reboot the printer

Confirm proper functionality

• Check if the touch panel issue is resolved

To avoid potential damage to your printer, always ensure that you download and install the latest firmware version specifically designed for your model. Installing incorrect firmware may render the printer inoperable.
