Hi everyone. I have a problem with my Xerox WorkCentre 7328. When copying some papers or sending documents for printing it randomly (as it seems to me) returns me blank sheets. It can give me a couples of blanks in the beginning of print job and then proceed normally or it can print documents without troubles for practically all day and then later start printing blank pages. Its warranty expired some years ago and local printer-repairing guys tell me it's all because of printer's mainboard fault which costs 90% of printer's price so I can just waste it now and purchase a new printer. Does anyone have any information regarding such problem?
