Blank print when photocopying

[pengtech]

Hi guys, I have a APIIC 4300 that has blank print(totally blank) when photocopying. The other functions like scan to PC, printing from PC, internal test print, report printing, they are OK. it only happen when copying is made either B&W or color. it happen on feeder and platen glass. Today I have changed the IIT unit but failed.
Any suggestions how to solve this problem.. many thanks..
