Good day. Did you correctly activate the firmware with the license key?

Good day. CA08P9 is only a few months old, you need an older version. Try this one from epson archive and report the results, in particular if the version is changed after update process: https://download3.ebz.epson.net/dsc/f/03/00/15/88/80/08ab2c159922c7920d9730e03ad7990fb5ef5f0b/FWCH70TL_CA29O5.exe

Good day. Please, explain your problem in more details step by step. Do you have 3rd party cartridges? CISS system? When exactly they stopped being recognized, right after update? You said you already downgraded firmware, how, when? The more information you provide the more likely we will be able to help.

If it is okay, I can connect to you remotely and check the problem myself, please, write me in the PM if you want to proceed.

Good day. I'm not sure what exactly is the problem. Can you input text in different field? Are you trying to type or copy/paste it? If it is acceptable I can connect to you remotely and check it myself.

Good day. Unfortunately, it is impossible to tell, even if the problem is indeed with firmware compatibility and not with the cartrdiges themselves we did not test every combination, far from it. I'm afraid the only way to tell for sure is to try it.

Good day. According to the epson database ET-3700 uses C13T04D100 mainteance box that has a chip so internal reset is not possible.

Unfortunately, this is how the chipless mode for this specific model operates, not much can be done at the moment.

Good day. At the moment trial reset is only possible if printer is already blocked, there should have been relevant error message during the reset process.

Good day. 1. Ink levels are stored on the ink cartridge's chip and data on the chip will not be updated while chipless firmware is installed, so, while ink will be used, information on the cartridges left unchanged. 2. Yes, you can restore original firmware afterwards though using it just to clean nozzles sounds rather expensive.

Good day. It looks like you opened the file directly from the archive, please, extract it first in the separated folder.

Good day. If a printhead has more letters than required then it is probably from the other (presumably compatible) model. What is the part number of the replacement head? Also, this string basically encodes a sequence of bytes with ascii symbols each byte written to the corresponding location in the eeprom. If there are more symbols that required then there are no reasonable way to reduce it to the shorter form. Moreover, while writing head id can improve or fix printing quality, its absence should not be a cause of fatal errors, so if this is the case then the problem most likely with something else.
