Need Help with ET-2760

[DWB-777]

I already posted about this in the Issues section (#117), but since I'm desperately looking for help, I'm posting this here in the Discussions section too. (My apologies if duplicate posts are not allowed.) Please take a look and I would really appreciate any kind of advice or help. Thank you.

A few days ago, my printer started showing an E-11 error, so I downloaded Epson Printer Configuration v7.1.0 and attempted to reset the waste ink counter.

My printer model was not listed in the software, but after searching online, I found that the ET-2756 supposedly shares almost identical hardware/configuration with my printer. When I selected ET-2756, the software detected my printer successfully, so I proceeded.

The only thing I did was click the "Reset Waste Ink Levels" button. I did not attempt any EEPROM reading/writing manually because I was too afraid of damaging anything. However, I did save the EEPROM values beforehand as below because it advised users to note them down in case of problems.

[NOTE] Current EEPROM values for Raw waste reset: 48: 255, 49: 255, 47: 255, 52: 255, 53: 255, 54: 255, 50: 255, 51: 255, 55: 255, 28: 255.
[NOTE] Current EEPROM values for Main waste: 48: 255, 49: 255, 47: 255.
[NOTE] Current EEPROM values for Borderless waste: 50: 255, 51: 255, 47: 255.

Unfortunately, after the reset, the EEPROM data appears to have become corrupted, and now the printer no longer functions properly.

When I checked the Maintenance Status page as shown above, almost every page counter is showing the maximum possible value of 4294967295. This makes me suspect that either the printer is referencing invalid memory addresses or the EEPROM data may have been overwritten with all 1s. Even stranger, the "First Printing Date" now displays as 2127-15-31, which is obviously impossible. That makes me think some EEPROM region has been corrupted or overwritten entirely.

When I re-ran Epson Printer Configuration, the EEPROM values now showed this instead:

[NOTE] Current EEPROM values for Raw waste reset: 48: 0, 49: 0, 47: 0, 52: 0, 53: 0, 54: 94, 50: 0, 51: 0, 55: 94, 28: 0.
[NOTE] Current EEPROM values for Main waste: 48: 0, 49: 0, 47: 0.
[NOTE] Current EEPROM values for Borderless waste: 50: 0, 51: 0, 47: 0.

This is the current printer behaviour :

• When powered on, it first shows "Service required"
• After pressing OK, it asks for language setup again
• After selecting the language, it shows "Preparing"
• The printer then makes various mechanical noises for a while
• Eventually it throws W-01 error:
  "Paper jammed in Back Side or Inside. Remove the jammed paper."
• There is absolutely NO paper jam inside the printer

Once again, the only thing I did with Epson Printer Configuration v7.1.0 was click the "Reset Waste Ink Levels" button. I was far too afraid to even attempt anything involving EEPROM reading or writing, so I never touched those functions at all.

For reference, the only other thing I tried afterward was entering the printer's SP Mode and selecting "STG OK" under Board Check, but the printer showed absolutely no reaction or change whatsoever.

At this point, I believe the EEPROM data somehow needs to be restored or repaired before the printer can function normally again, but this is far beyond my technical ability.

I'm desperately asking for help from anyone knowledgeable about this issue with EEPROM recovery or repair. Please help me save my beloved 7-year-old printer from becoming e-waste.

You can check "Detect Access Keys" and find which other model shares the same EEPROM pattern

Hi, this is what I get...

[INFO] Starting the access key detection, please wait for many minutes...
[INFO] Detecting the read_key...
[ERROR] Printer is unreachable or offline.

The printer is currently connected properly, yet it keeps showing the exact same error message no matter how many times I try. :(
