Changing the wiper blade on Epson 4880

Has anyone found the best way to remove and install the wiper blade in an Epson 4880 ? I have searched for 3 days and cannot find any specific instruction on how to get to the blade and remove it.
Thanks

The factory manual is at EpsonWideFormat@groups.io | Home

I have all 3 of the manuals. I went to and joined the group. After reading all the manuals. After countless searches. After asking all I can. I cannot find an exact description on how to remove and replace the wiper blade on an Epson 4880. I believe that it may be a case of thinking too much. Just pull out the old one and push in the new one might be all I have left.
