iR 3035 / 3045 dots on scanned documents

[lionex3d]

have anybody encounter this issue?

when scanning using universal send ( send to file,email,ftp )

the documents sent will have alot of random dots/spots

the sample document is a blank paper so the spots will
be more obvious,

while troubleshooting, this are some of the things that I found out:

this dots appear when using either the ADF or the platen glass

this dots does not appear on photocopies.

this dots does not appear when the original is scanned
into the mailbox (and then printed out)

this dots does not appear when the original is scanned
using pull scanning (network scangear)

another issue:
when using the ADF as you can see on the attached document, the alignment is slightly off. The cutoff margin on the top and right side of the document are visible, however the alignment is almost perfect when using as a photocopier. is there anyway to sync the alignment when using the adf for scanning and photocopying?

Yeah, a bit unusual - have you tried adj White Balance (I haven't a manual handy but something like this) COPIER > ADJUST > DFWL1 > DFWL2 - dfwl1 put a sheet of white paper on glass press ok/start - dfwl2 same sheet in DADF press ok/start (sorry about the umm ahh) this setting/adj is used when the Display message 'Clean Scan Glass' appears, and the adjustment is usually overlooked in the initial run-up of the Machine.

Hope it helps.

Hi, thanks for the suggestion

I tried but still have dots

funny thing is it's not a one machine case only

I have been having this problem from a few machine already

including some iR C3380i

hoping for more suggestion

Fully cleaned the optics? Use a flashlight when you clean them so you can see the slightest dot. Clean the underside of the glasses with alcohol/windex as well as the white plate.

Call me crazy but if you look at that document in the middle there are consistent dots going lead to trail. Pointing to a drum/dev/fuser issue. To me looks like a nic on the drum. I know you said it doesn't show up when photo copying but I would check again just to be sure.
For it to have that kind of issue ONLY when smb, email, ftp and not doing it with pull scanning or mailbox just does not make sense. If you are having issue in the reader control part of the machine it would be no matter where you send it to. I have circled the consistent lead to trail marks. For experience techs reading this, tell me that doesn't look like a drum nic. (SEE ATTACHED)

very good eyes there ninjatech
one thing thou... this is a fresh paper, means it didn't pass through the printer section of the copier machine.
another thing, I recently installed a fax on a 3035 machine with the same issue and found that it also affects faxed documents, although not so obvious compared to documents send via smb/email. one of my colleagues told me that playing with the resolution (ppi) can gradually increase/decrease the dots and on 2880/3380 sending using gray instead of black also decreases the dots. I have not personally tested this (maybe later) but maybe you guys can take this into consideration. anybody know which part of the machine controlls this? is it the reader controller? mainboard?

thanks!

Don't know if you were being sarcastic or not but anyways I know that's why it looks like it has went through a machine. I can't imagine anything else causing that. This seems like an issue that one would have to be there and see it happen. Is it random dots? Or all in different patterns? Oh and ccd sends it to the reader controller then main controller, out through the nic, In basic sense. If it's something within that process I can not imagine it being anything pass the ccd.

no no no, I was not being sarcastic.
I just really didn't see the dots lined up that way.

It is random, scanning the same paper several times would
always show dots on different areas on the document.

so it will be the CIS -> reader controller-> mainboard for this model
i will try to troubleshoot by changing parts once I found
a machine that doesn't have this dots issue

I used to have an issue with the 2880/3380 universal send
but it was random horizontal lines scattered on the document
when scanning, it was solved by changing the sub R-A pcb on the mainboard.

will keep you posted
