Funny, I circled back to this thread that I originally started back in 2014 to answer a question.
Check transfer roller on side door. The contacts that mate with machine when door closed may need to be re-shaped to make better contact. Did you stop machine mid-cycle to see if image is on trans belt? is this happening when copying & printing internal test pages?
Hi, Thank's for reply
No image is forming on Transfer belt and no mater where the printing is comming, print reports, test, copy or computer just blank pages.
I had another c253 with mechanical problems and i change from that all the boards except Power Supply
i will try what you sugest.
Did you change the laser drive board (LDDB) ?
Sounds if nothing at all happens to build an image.
In that case if you don't have an image on belt and you have replaced HVPS then look at laser unit. Not sure about the color 4 series if all 4 lasers would go out, but I've had several newer B&W bizhubs give blank pages and NO codes! Most recently a bizhub 363. I was expecting a code if the laser was bad so I did what you did and replaced the HVPS, A board, Image unit and it turned out to be the print head laser unit.
