Add new printer on ET series

[MWMatthieuBR]

Hello,
First of all thank you for your program, you saved one of my 2 printers !!!
I followed your instructions to add a new printer with the link on Codeberg, because my first printer is an ET-2756 but the second is an ET-2856 and it is not in your program.

The command only gives me parameters on ET-2851 ET-2853 ET-2855 for the 2850 series, I tried to reset the counter with that but it doesn't work, when I restart my printer I get error E-11.

Can you help me to understand why ? Thank you !

Good to know that the ET-2756 is working well. However, I'm not familiar with the ET-2856 printer, so I recommend against testing unfamiliar models. Also, please be aware that this program doesn't save the old values before replacing them. If possible, you could try reading the following addresses from another printer of the same model and then save them on yours: 48, 49, 47, 52, 53, 54, 50, 51, 55, 28.

Hello, i view your commit and git reset to have it.
The config given by codeberg is :

 "ET-2850": {
            "alias": ["ET-2853", "ET-2855", "ET-2851"],
            "read_key": [74, 54],
            "write_key": b'Arantifo',
            "main_waste": {"oids": [48, 49, 47], "divider": 109.13},
            "borderless_waste": {"oids": [50, 51, 47], "divider": 16.31},
            "third_waste": {"oids": [252, 253, 254], "divider": 15.3},
            "raw_waste_reset": {
                48: 0, 49: 0, 47: 0, 52: 0, 53: 0, 54: 94, 50: 0,
                51: 0, 55: 94, 28: 0, 252: 0, 253: 0, 254: 0, 255: 94
            },
            "stats": {
                "Total print pass counter": [133, 132, 131, 130],
                "Total print page counter - rear": [755, 754, 753, 752],
                "Total print page counter - duplex": [763, 762, 761, 760],
                "Total scan counter": [1843, 1842, 1841, 1840],
                "Ink replacement counter %-- Black": [554],
                "Ink replacement counter %-- Cyan": [555],
                "Ink replacement counter %-- Magenta": [556],
                "Ink replacement counter %-- Yellow": [557]
            },
            "serial_number": range(1604, 1614),
        }
     

But with the new code I get an error because he received none for the values :
[ERROR] int() can't convert non-string with explicit base
Traceback (most recent call last):
File "C:\Users***\Desktop\epson_print_conf\ui.py", line 678, in get_current_eeprom_values

But with the new code I get an error because he received none for the values :

This is because you are using a wrong printer model, with a different "read_key" or "write_key" than the interfaced printer and the SNMP requests fail. Now appropriate error messages are produced instead of the Traceback.

I test with your new version of the project and your answer is good i don't have the good read_key :
ex :

  ADDRESS: 1.3.6.1.4.1.1248.1.2.2.44.1.1.2.1.124.124.7.0.74.54.65.190.160.54.0
  OID: 54=0x36
DEBUG:root:  TAG: OctetString
  RESPONSE: b'\x00||:41:NA;\x0c'
INFO:root:Invalid read key.

But i don't know how to get it. Do you know how ? thanks !

Version 3 includes the "Detect Access Keys" button, which attempts to discover the read_key and write_key of the printer.

[PUN-app]

For the ET 2850 using v5.1(IP present but hidden with x)...
[INFO] Detecting printers... (this might take a while)
[INFO] Found printer 'EPSON ET-2850 Series' at x.x.x.x (hostname: Unknown)
[ERROR] Printer model unknown.
[INFO] Starting the access key detection, please wait for many minutes...
[INFO] Detecting the read_key...
[ERROR] Could not detect read_key.

[MWMatthieuBR]

Same as @PUN-app using the last version, can't detect the read_key..

@Ircama I'm just here to report success on an Epson ET-2825, which is the same modell as ET-2820. Thank you for all the effort you took into this project.
To get it working with the ET-2825 I had first to FW downgrade the printer to FW XE18MB from XE120B via WicResetUtility (printer has to be connected via USB for this), since FW XE120B does not support EEPROM access via WIFI but FW XE18MB does. Got the printer definitions imported into epson_print_conf from Codeberg via toml file.

Actually I did reset it at first via Linux and the https://codeberg.org/atufi/reinkpy project. Afterwards I got carried away and explored if it isn't possible via epson_print_conf.exe too (I'm running it on a Win7 machine and used epson_print_conf.exe v5.3.6) and found the solution via firmware downgrade. The WicResetUtility I used was version 5.90.
