Bizhub 350 service code

Sep 15, 2008

-   I have just bought a Minolta Di450. The first time I used it, I used the Electronic Document Handler, copies two-sided from single sided, sorted, and stapled the stack. The copy was a little light and had a single line run horizontally on most of the pages. There was also a line about one inch wide on some of the pages.The originals are 16 sheets making the copies 8 back to back sheets. Half way through the stack, the back of each sheet has faint "ghost" copies. This "ghost" text came from the back of the previous sheet. The 16 origninals are numbered on the bottom center beginning with #49 and running to #64. Every even number (the back of each odd number) has the page number copied lightly - a "ghost" image- on the top of the page centered. Does code C-OBAO refer to these problems? And if so, what do I do about it.? Can I deal with this myself, or do I really need to call a technician? -   dwinfrey
