I'm rereading the Piezo manual and going through the checklist to hit the ground running when my Piezo SE comes in for my 7800.
In the Piezo manual it says to hold down all four buttons when turning it on to get to the Service Menu. I get a reading that says update the firmware. So I've gone through the Epson support site numerous times. Trashed my print driver and reinstalled. Confirmed the driver is updated. The Epson LFP Remote Panel shows up on my Printer Utility but it is not responsive.
I suspect its not the end of the world but I would like to do the initial ink fill procedure as opposed to purging inks and power cleaning.
I did a forum search for 7800 Firmware issues but nothing came up.
Also do you have a supplier to recommend to buy items such as dampers and other items that need replacing from time to time?
