  1. It is no secret that in recent years, Epson has a tendency to bring trouble to the users under the guise of updates, particularly printer firmware updates. The next step in this direction was the replacement of some communication protocol specifications for a number of models, which makes waste reset and working with the printer via WIC when using Wi-Fi impossible. The main symptom that indicates the presence of this problem is the message "Query is rejected" when trying to perform any operation, including waste reset, as well as the firmware from the 2023 year or later (fifth letter is either N or O in the firmware name, for example CB10NB).

    At the moment those models are affected:

    L3250 (ET-2400 ET-2810)
    L3260 (ET-2800 ET-2820)
    L4260 (ET-2850)

    WF-7820
    WF-7830
    WF-7840

    The only solution is to either use USB connection or to downgrade the firmware to an earlier version. WIC provides a number of free 2022 firmware versions for the models from the list. To perform the downgrade you need to do the following:

     

    1. Start WIC and unfold "Firmware Update" section (printer must be connected via USB).

    2. From the list of firmwares select newest version available:

    3. Press "Update" button to the right of the list and follow the instructions:

    Once firmware downgrade is succesfully finished, printer should work normally with the WIC.


  2. Good day. They use same firmware, different settings such as default language, displayed model name, default paper size and so on are controlled via various flags in the eeprom. As for the second question, as far as I know any printer will work with any version of the windows as long as there is a driver available and discribed limitations do not exist. Can you show where is says otherwise?


  3. Good day.

    In order to disable this mode and return to the normal state you need to upload eeprom from the working device with WIC, like the one attached to this post, unfortunately, this will not help to recognize the ink cartriges but you may also install chipless firmware to bypass the problem altoghether. That said there are might be other hardware problems that will only become apparent after printer completed initialization routine so I can't guarrantee that it will work in the end.

  4. It is true only for models that use the same firmware as their western analogues, most of the time you can tell by the first two letters in the firmare version, if they are the same and models are from the same generation and look similar then more likely than not it will work. Sometimes firmware prefixes are reused by Epson, but usually only when there are several decades between the series.

    SC-PX5VII is supported, for any other models you need to ask specifically.


  5. Good day.

    Please, try to update in the service mode first and report the results.

    To enter the service mode, follow this instructions:

    First method:
    Turn off the printer then press UPPER RIGHT CORNER OF THE TOUCH PANEL (#1 on the photo below) + POWER simultaneously.
    Hold them for about 20 seconds.
    Release this buttons when power indicator is ON, printer LCD will display "Program Update Mode" in WHITE color.

    Second method:
    Turn off the printer then press UPPER RIGHT CORNER OF THE CENTER OF THE TOUCH PANEL (#2 on the photo below) + POWER simultaneously.
    Hold them for about 20 seconds.
    Release this buttons when power indicator is ON, printer LCD will display "Program Update Mode" in WHITE color.

  6. Some versions of Windows 10 have an issue where application may freeze when trying to communicate with the printer unless the first query is sent via the driver. To resolve this, please, do the following:

    1. Restart the printer.

    2. Install printer drivers if you don't have them yet.

    3. Start the printer's status monitor and wait until it reads the current status.

    4. Run WIC as an administrator and disable all Epson processes via the support menu (including status monitor). To do so, select "support > disable processes" in the main menu in WIC and then click the "terminate all" button.

    5. Try to reset again.
