hey guy.. need some comments and sugestions here..
We've been working this problem since last monday..
I came for a service for ineo+6500 with error of c4520, color registration problem..
Okey, i cleaned the Transferbelt, realign it and clean registration sensors (ps9 and ps8)
Then came the C2802 which is gamma sensor of K, i cleaned it,
Then came the C2451,which is TCR sensor of Yellow, so we decided to replace yellow developer since its already in red..
Upon removing OLD developer, we notice that the OLD developer is not yellow anymore, it turns "BLACK" as in if you spread it on your hand, black color will prevail and yellow can never be found.
Okey, then we load new developer and successfully finish auto developer charge..
Then came back C4520, we replace transfer belt and color registration, same! it rolled for almost 3 days, and we had even change the Print control board..
but still same,
until earlier, we decide "what if we change new developing unit" okey then we change and this what we have notice again, the new developer we loaded last days is now not a yellow developer again, it turn black again.. (to those who might ask, yellow toner is in position and never swap)
OKey, then we put the new developer and developing unit..
then came 2461..
but the yellow charger chorona is not broken nor burned..
We swap charge from other color and drum potential sensors and board, but 2461 still prevail...
Hehehe! too long??
Need some suggestions guys!
