Hello,
The European support site has information about the Epson Software updater and Uninstall Center only, when choosing macOS 11 (Big Sur) as the operating system:
https://www.epson.eu/support?productID=10816&language=en&os=38#drivers_and_manuals
The Epson Singapore support page on the other hand has a Big Sur driver:
https://www.epson.com.sg/c/Epson-AcuLaser-C1700/s/SPT_C11CB71061?review-filter=Mac+OS+X+11.x
Apparently, this driver, Ver.1.12 (03-2014) is used for earlier operating system versions as well.
Going back to the European site, with macOS 10.15 (Catalina) chosen as the operating system, there is a 1.14 (04-Jan-2021) driver:

So, you may have to check what the operating system or the Epson Software updater offers to begin with (after having reset the printing system, and re-added the printer). Otherwise, you may want to try one or more driver downloads. You should look upon this as an experiment. Software conflicts cannot be ruled out. You may have to erase and reinstall everything on the computer. Data can be lost. So, do not proceed unless you know what you are doing. Also, make sure that you have multiple backup copies of important files before doing anything at all.
