[y_us1982]

hi..
i had faced image get blurred on 2nd side when i'm running duplex mode on my ir5570. it get blur only 1/4 page on 2nd side. i wonder what the problem, i had replace all the wires, also had clean the drum but the answer still the same. what makes me thinking is, the blur doesn't get at all the pages, it appears after 8 or 10 piece then it will be ok, then after 8 or 10 piece of paper it will get blur again. anybody had any idea on this situation... hope can hear from all the experties out there. thanks...

adjust the fixing inlet guide Up 1 mm on both front and rear sides.

check your steel roller in duplex for wear #25
Steel roller, (part number FB5-3322-020) along with the washer, item 66 (part number FS5-6488-000) and the bearing, item 78 (part number XG9-0192-000)
