Symptoms
When connecting the scanner, various types of connection error messages appear in the software, or the Wireless Hub (Cradle) is not recognized by the PC.
- “Connection failed” message when the scanner tries to connect to the router.
- Bluetooth pairing failure message when connecting the scanner.
Troubleshooting
A. When using a router for Wi-Fi connection
1. Check the scanner status
Confirm that the scanner LED is blinking white.
If it shows a different status, proceed with the following steps:
- Reboot the scanner (press the battery power button, make sure the battery LED and the scanner LED are off, then turn it on again).
- Remove and reattach the scanner battery.
- Close and restart Medit Scan for Clinics.
2. Check the Bluetooth status
Bluetooth is required during the initial pairing (connection setup) process when connecting via Wi-Fi.
- Check if Bluetooth is turned on in the PC/iPad.
- Check the distance between the PC/iPad and the scanner.
- If multiple devices are connected, disconnect those other than the scanner.
After confirming the above, reboot the PC/iPad.
Turn Bluetooth off and on again, then attempt to reconnect.
(On iPad, delete the registered Bluetooth list and try again.)
3. Check Wi-Fi Status
Refer to the linked document to check your Wi-Fi environment.
[Guide] Recommended Wi-Fi Specifications and Installation Guide
If there is no issue with the Wi-Fi environment, proceed with the following steps:
- Disconnect and reconnect Wi-Fi on the PC/iPad.
- Restart the router and try connecting again.
4. If Wi-Fi connection via router fails, connect the Wireless Hub (Cradle) and try again using another method.
If the issue persists, professional assistance may be required.
Please submit an inquiry including the details of your inspection, which will help in resolving the problem.
⚠️Caution
If the Pairing Manager does not appear in Medit Scan for Clinics, check whether the Mobile Scanner Connection function under Scanner in the settings is turned on.
(Default: On)
B. When using the Wireless Hub connection
1. Check the scanner status
Confirm that the scanner LED is blinking white.
If it shows a different status, proceed with the following steps:
- Reboot the scanner (press the battery power button, make sure the battery LED and the scanner LED are off, then turn it on again).
- Remove and reattach the scanner battery.
- Close and restart Medit Scan for Clinics.
2. Check Wireless Hub Status
When connecting with the Wireless Hub, the hub handles the initial pairing (connection setup) process.
- Check the distance between the Wireless Hub and the scanner.
-
Check the hub’s connection status.
Disconnect and reconnect the cable between the hub and the PC.
When the hub is connected properly, two devices will be visible under Device Manager.
If they are not visible in Device Manager, there may be an issue with the connection port or the Wireless Hub.
Try connecting the hub to another USB-C port or to a different PC. - Uninstall Medit Link, then download and reinstall the latest version.
If the issue persists, professional assistance may be required.
Please submit an inquiry including the details of your inspection, which will help in resolving the problem.
Symptoms
The scanner disconnects intermittently or scanning is slow.
Troubleshooting
1. Check Wi-Fi Status
Refer to the linked document to check your Wi-Fi environment.
[Guide] Recommended Wi-Fi Specifications and Installation Guide
2. Check Laptop/iPad Charging Status
- For laptops, the charger must be connected to prevent performance degradation.
- For iPads, performance may decrease when the battery is low due to power management, and performance may also degrade due to heat while charging.
Symptoms
When i900 Mobility is connected, if the Medit Link Express app is sent to the background, the connection is lost after 1–2 seconds.
[Example Scenario]
When pressing a button in the Medit Link Express app that connects to a website (e.g., the “Manage Account” button in Clinic Profile), the scanner connection is not maintained.
Troubleshooting
Reboot the scanner (press the battery power button, confirm that the battery LED and the scanner LED are off, then turn it back on).
⚠️ Caution
Do not leave the Medit Link Express app in the background; keep it running in the foreground.
Symptoms
During scanning, if the battery is removed or the power button is pressed to turn off and then on again, the connection fails.
- Wireless Hub (Cradle) connection method: It attempts automatic reconnection, but the connection drops, and after repeating 2–3 times, reconnection becomes impossible. At this point, Medit Scan for Clinics shows the scan button as active.
- Wireless router connection method: Automatic connection to Medit Scan for Clinics fails, but manual connection is possible.
Troubleshooting
Reboot the scanner (press the battery power button, confirm that the battery LED and the scanner LED are off, then turn it back on). Depending on the situation, two reboots may be required.
Symptoms
At the first connection, it works normally, but after rebooting the PC, the Wireless Hub (Cradle) does not automatically reconnect to the scanner.
Troubleshooting
Disconnect and reconnect the USB cable to the PC, and it will be recognized and reconnected normally.
Please check the following items to ensure that automatic reconnection functions properly.
1. Device Power Management Settings
1) In Windows Device Manager, find and click Medit Device > Medit i-Series wireless
2) With the device selected, go to View > Devices by connection
3) Check the USB port to which the device is connected (Generic SuperSpeed USB Hub)
4) Right-click the identified USB port (Generic SuperSpeed USB Hub) > Select Properties
5) Power Management > Disable “Allow the computer to turn off this device to save power” > OK
2. Windows Power Options Settings
(Depending on the environment and manufacturer, some options may not be visible. If so, proceed to step 3.)
1) Control Panel → Power Options → Click Change plan settings
2) Change advanced power settings → USB setting → USB selective suspend setting: Disabled
3. Connect using another USB port.
4. Chipset Driver Update
Update to the latest chipset driver via the motherboard/laptop manufacturer’s website or by using a 3rd party driver update utility.
5. BIOS Settings Change (USB power-off related options)
-
Through manufacturer-specific BIOS settings, you can control whether USB power is supplied after system shutdown (S5) or sleep/hibernate (S4).
System shutdown = S5 (Soft Off)
Hibernate = S4 (Hibernate) - Manufacturer-specific USB power management BIOS options:
| Manufacturer / Applicable Environment | BIOS Setting Option Name |
Function Description (Based on S-States) |
|---|---|---|
| Common and Motherboards in General (Asus, Gigabyte, etc.) | ErP Ready / EUP | Cuts off USB power after shutdown (S5) |
| HP (EliteBook, ProBook, Omen, etc.) | USB Charging in Powered Off State / Alaways On USB | Sets whether USB charging is available in shutdown (S5) state |
| MSI (Gaming, Creator Series, etc.) | USB Standby Power at S4/S5 | Controls whether standby power is supplied to USB ports after shutdown (S5) or sleep (S4) |
| Dell (XPS, Alienware, Latitude, etc.) | USB PowerShare | Sets whether USB power is supplied during shutdown (S5) or sleep (S4) (varies by model) |
| Lenovo (ThinkPad, IdeaPad, Legion, etc.) | Always On USB / USB charging in S4/S5 | Sets whether power is supplied to specific ports during shutdown (S5) and sleep (S4) |
Symptoms
When attempting to use i900 Mobility simultaneously on two PCs where it is registered, malfunction occurs.
[Example Scenario]
PC 1 and PC 2 both have the same scanner registered.
Medit Scan for Clinics is launched simultaneously on PC 1 and PC 2.
On PC 1, the scanner is turned on (connected after Bluetooth pairing) → PC 1 connects normally.
At this time, PC 2 also continues to attempt Bluetooth pairing, causing a conflict.
Troubleshooting
1. Close Medit Scan for Clinics on both PCs.
2. Reboot the scanner (press the battery power button, confirm that the battery LED and the scanner LED are off, then turn it back on).
3. On the PC you want to connect, launch Medit Scan for Clinics and reconnect the scanner.
Symptoms
The power does not turn on even when the battery power button is pressed on the scanner.
Troubleshooting
1. Check battery charging status
Press the battery power button. If the battery LED lights up blue, it is charged.
2. Check battery installation status
Remove the battery, then reinsert it properly into the scanner.
(Since it attaches magnetically, no force is required.)
3. Try another battery
Replace with another fully charged battery, then press the battery power button again to check.
If the issue persists, professional assistance may be required.
Please submit an inquiry including the details of your inspection, which will help in resolving the problem.
