Canon IR3180ci Blank Pages?

[teckat]

Is there a way i can check to see if an image is forming on the drum?

No,

The previous latent image on the drum is removed and the drum is conditioned for the new latent image. ... As the drum turns, an invisible latent image is created on the drum.


Simple troubleshooting , if u get patches formed on ITB, and they don't transfer to Paper, U need to look at your secondary transfer roller operation.

Forming of the Patches or images from Printing or Copying on ITB prevents Error Codes.

If nothing was being seen by patch sensor u would get development error codes.

There is a copier charge contact that needs to make good contact with the secondary transfer roller, check both these contacts.

Replace the ITB if in doubt, especially if it has done over 300k.

Only recent error code was E0732 that was related to paper pickup rollers on cassette one that were worn down and not picking up, new ones fitted and seemed to sort it, but nothing related to this blank page problem.The machine has recently had both cyan and magenta dev units replaced and weirdly since then has made an audible beep? when printing, but has printed ok.This was a couple of weeks ago but now is printing only blank pages,there was no audible beep on the old dev units?.

Error code E0732 has nothing to do with paper feed.

Are you a tech?

Thanks for responses, no i'm not a tech so forgive me if i get any of this wrong, would a second transfer issue prevent prints/copies (inc internal prints) from being formed on itb as i get nothing this way?,have also tried from pc but nothing,i can understand a transfer issue if images are on itb.

The fact that you can see the patches formed on the ITB but not when you print? Try a PG10 test print run stop the machine mid run (open the RHD) are you SURE there is no image on the belt?

[steve1973]

Checked itb through right door during mid PG10 run, nothing on itb?,apart from the smallest amount of toner, (very small amount),and still prints blank page.May be nothing to do with it but still get the beeping tone for each colour, its never done that before?

[copier tech]

Can you post a video, not sure what you mean about a “beeping tone” for each colour!?

[steve1973]

Here is a video to try to demonstate the beeping noise, there are two beeps one louder than the other, there at 10secs and 14secs as image is being formed (obviously ignore the last beep as its normal)

[steve1973]

Video quality is not great but had to reduce a lot to upload it,as you can see still on blank pages.

Update - this problem has now been solved, the offending item was the laser scanner unit, have replaced it from a donor machine and is now working ok, no idea what was wrong with it?,all the machine would produce on itb was patches at startup, other machines may have similar issues due to this, many thanks to all who posted a response.
