MH-ET Scanner not working after reset

I am troubleshooting my barcode sensor since it is not consistent in reading the barcode, I search for datasheet and found out a QR for restore factory function. I tried to scan it and the barcode scanner stops reading barcodes and always turns on. On other data sheets I found some QR codes to be used when accidentally scanned a restore factory QR but it didn't solve the problem, the scanner still can't read the barcode.
This is the actual problem, it is stuck on that state, it never turns off but it is not able to read barcodes anymore.

my scanner is MH-ET LIVE Scanner and I need to read the data on a block note

What data sheet?

Sorry I do not do well with invisible datasheets. Post an annotated schematic showing exactly how you have wired it Be sure to show all components used including capacitors, resistors etc, connections, power connections, ground connections. Links to any hardware device including the Arduino that gives technical information. Frizzes (wiring diagrams) do not count as schematics (the language of electronics) for me as they do not contain the needed information. Remember we are trying to find a problem not assemble it.

Iused the manual in this site : https://www.tinytronics.nl/en/sensors/optical/cameras-and-scanners/mh-et-live-barcode-scanner-v3.0

I used the configuration in the manual in this site :

Still waiting. I will check back in a few days to see if you posted the schematic. I do not have the time to chase over the WWW trying to find technical data when your link does not take me there, The information in the zip file is not complete.

I connected the scanner to the PC via USB, there is no schematic here. my problem is that after I scanned the QR Code for "Restore factory defaults" and the barcode scanner stops reading barcodes and always turns on and is not able to read barcodes anymore. have you faced an issue like this before

No, without the schematic I cannot help you.

What manual?

Scanner v3.0 QR code module specification (3).pdf (1.3 MB)

What configuration?

inside the PDF there is QR code configuration I scanned them

Hello Mr. Mohamed_Said. Please, provide the project and configuration information here. Links and zips are not seen as information.

i also have the same issue, how do i solve this?

You should try this

my scanner remain all lights on, button not function and cant detect barcode

You need to read post#15 again

thanks for the help <3

Can you explain how did you fixed your barcode scanner? It will help others having same problem
