  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.

  I purchased the epson adjustment program last night and got to work on it today.
I had a clog in C and it would not clear. I ve had my 4900 for over 2 years and have been able to handle them until now.
I learned about this site from another site that has cleaner for the 4900 and said I need to buy this software first. I bought it and tried it with the epson ink that was in my printer. I ran the adjustment and it cleared C but then there were other clogs. Because they werent clogged before I started, I cleared them the normal way through the printers options. Had they not cleared, I would have ran the adjustment again.
I had tried everything to get C to clear for a week and this program did it in one try!

I would highly recommend this for clearing a stubborn clog. And now it is in my arsenal if I get another one that I cant clear down the road. By the way, it does not work if your printer is networked. Mine was so I had to move a computer into the room with my printer, directly connect to it and install the drivers. Then it work fine.
If you got a clog that you cant fix, just buy it.

  Printer reset with key then failed waste counter back to 100% after test print. Key no longer works!

2Manuals reply:
There is bug in Epson Photo 1390, 14000, 1410 firmware that put waste counter overflow back again after reset. This problem can be solved by updating printers firmware. Here is step by step manual how to fix it - www.2manuals.com/1400fw_update.php
