Hello!
My Ricoh Aficio 2105 when copy/print in duplex mode,always paper missfeed the latest page.
It showed me an error code SC401 and after i cleaned all contacts of TB and second transfer roller,the error never appears anymore.
But,the problem is printing and copying in duplex mode and missifeeding paper in the last page,is something new for me.
Ricoh AF2105 has a network based controller(printer/scanner kit).
Please somebody is experienced with this kind of machines helps me.
Best regards to u
