I have this issue when printing, printer starts to print some random glyphs on all the pages, i've read it is software update issue, and i did UPGRADE WIZARD via Centre Ware page, I did it 3 times..
But it is stil showing me Firmware version from FEB-2015
i'am trying to install this latest osx monterey files :
09/20/2021 / 3.50.02.05 / 11.38 MB / PH3052_3260_V3.50.02.05.zip
2021 mac M1 with monterey os.
Maybe there is another way to get rid of this glyph printing, i've lost so many paper..
thanks in advance
today i tried run update again via cable
and again its shown that my firmware is from 2015
