Could you please share these firmware versions with me? My HP PageWide Pro 477DW printer is not printing after the update. I was able to downgrade to version 1908, but I need an even earlier version. Thank you in advance, Igor.

Hello. I am searching for older firmwares:

PW477dw_001.1829A.ful2
PW477dw_001.1839A.ful2
PW477dw_001.1850B.ful2

Does someone now the error with "supply system" on pagewide477pro with third party cartdiges?

When i test a original 971x and glue an self reset chip on this cartridge i get this fault too after several print jobs. When i remove this chip, and the original chip has contact to the printer it works pretty well.


I want to test different firmwares. I tried the 1908C, but they did not work.

Thanks, Hardy
