My Epson WF4640 returns an Error Message 0x97

There does not appear to be a single solution that always fixes this error message. For some users, procedures for cleaning the nozzles works. For others, switching the particular software program you are attempting to print with works. For a considerable number, contacting epson about your warranty (a year) yields a replacement printer being shipped. The approach from Epson for tackling this problem appears to be powering the printer off, detaching peripherals, reseating cartridges, waiting 5 minutes, an re-powering. Here is a link offering variations of this: https://tonixcomp.net/epson-error-code-0x97/

Which ever fix is employed, the ones which do NOT work include replacement of drivers, scanning for viruses, and firmware updates. Hope this saves you some time. I also note that this error message is not confined to a single epson model but it is generally a good thing to supply that model number as well as your OS when researching a problem.

How to fix an Error message on an Epson Printer

These codes can be indicative of a faulty sensor or damaged part.

But let's try this:

I have had similar issues with my MACs and HP printers, however I have often fixed the problem by re-installing the printer software and/or deleted the printer from the printer list in system preferences.
If you have the Epson disc fine...if not, the OS should be able to "find" it for you via the internet. try re-installing the printer software.
BUT you say that the scanner works via the computer.
Have you tried shutting off the Epson and unplugging it from the A/C outlet and unplugging all cables? Leave the cables out for at least 30 seconds and try again. This is the procedure for a forced re-boot of many printers. Hopefully, this will help.

I am on my second printer with the error. Epson explained it is a motherboard failure. The error is not caused by a PC or the software on it. Instead, this is a printer hardware failure.

After exchanging the printer, the replacement printer has now dies from the same error. The problem starts as blurry printing and progresses to the full hardware failure. Once the Hardware fails and you get the error code, there is nothing an end user can do. The motherboard needs to be replaced.

My printers were working fine up until I swapped out the factory cartridges that shipped with the printer. In both of my cases, there were no issues or symptoms until I started using the Epson XL cartridges. As soon as I installed those, the symptoms started to show. Within a couple of months after swapping in the XL cartridges, the motherboard dies.

Options:
1) Call Epson and complain, make them log the details even if it is out of warranty. This helps establish the pattern and knowledge of the issue.
2) Swap printer if under warranty. They may want a credit card to charge in case they do not receive the bad printer back. Just resend it in the box the replacement came in. Epson supplies shipping labels and covers the shipping costs.
