Zemirli computer 0 Report post Posted September 1, 2020 I have the same problem with wf 7710, when the maintenance box is full, it wont reset even when you replace it with a new one. wf-7710 was still working with chipless solution until the maintenance box message . firmware vertion : FA24I5 Share this post Link to post Share on other sites
John_Admin 388 Report post Posted September 2, 2020 If you already have chipless firmware in your wf-7710 printer and want to reset maintenance chip - restore Epson original firmware and replace maintenance box or reset maintenance chip by chip resetter, once maintenance box is recognized reupload same chipless firmware again and reactivate it with saved recovery key.
