I just replaced the black drum, black developer material and rebuilt the transfer belt unit with a new belt and cleaner. The old belt shredded the edges of the belt leaving junk all over the pages. Since then, when making any color copy or print, the machine is doing a rainbow all over the page. The guys I talked to said it could be the transfer belt unit, but I'm not familiar with the Toshiba copiers. Any help is appreciated. Thanks
