BizHub C253 blank pages

[copyman]

Blank (no image) copies & prints,happening with color and B&W. No error codes.

I did see the tech bulletin about replacing the PWB-PH board.

Anyone else ever see this? Account is far away and want to make sure to bring anything else it could be.

Thanks in advance

Check that the transfer belt is driving. I've seen the belt get damaged to the point where it gets stuck and the drive slips and will cause blank pages.

Start my stopping the machine mid run see if there is an image on the transfer belt & image units

Thanks for the help. Turned out the transfer belt was completely torn apart. Special thanks to wseyller, because of his post I had the transfer belt with me.

Really strange that it did not throw a code with a torn belt. I thought a sensor reads the edge of belt for movement?

Anyway all is good and machine is working now.

Thanks Again

Happy New Year

Not so strange really. In all the equipment I see, I can say the only transfer errors I've ever seen were primary transfer shift in the Kyocera Saturns. Even when the primary transfer belt is tangled in the pulleys, the only warning you'll get is some gear noise, and jamming.

Oh wait, and on the Kyocera Alphard series there was some problem with the primary transfer belt shifting to the rear, but that was resolved with updates to the transfer belt assy. =^..^=

On most Ricohs you will get ID sensor errors, but they only logged and not displayed on the panel.

Good to hear you got it going

There were several "P" warning codes but these type of codes dont stop the machine. The customer didn't see the oil can on display. If they would have told me about the oil can I would of had them read me the codes and if there were several P codes realted to Trans belt I would have figured it had to be something with that.

Just to clarify I have seen these belts tear but never this bad with complete blank page. Also damaged the black Image unit by some of the belt getting fed into unit and scratching drum.

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?

[gabitzzup]

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.

[copyman]

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.
