Ricoh SP C262SF Lines on copies only when using ADF: the slit glass is clean

[patterson70]

Hello, getting lines on copies when using the ADF but not from the glass.
Please see the picture.
The slit glass is completely clean.
I did repeated cleanings and checked with a magnifying glass and flashlight.
There is nothing on it.
So, I am thinking maybe some LEDs burned out but since I have never seen this before I wanted to check if anyone has seen this before.
And if it is the LEDs, is it worth repairing? I know the top is not easy to take off but it can be done.
Thanks for any advice.

Did you remove the scanner glass and clean the CIS?

No, I did not because the machine has been sitting in a very clean environment and it happened all of a sudden.
I just don't think any debris could have gotten in there. I'm thinking burned out LEDs.
Did not want to take it apart since they are still using it.
I think it's more of a shop repair than on-site unless you could correct me on that?
I have taken the top off before but it was a bit of a cumbersome noisy process and you have to unsnap and then later re-snap some panels, etc.

I checked the SM, it may have the "D-ADF" with double cis, one on the machine, and one on the adf, try to make a duplex copy both black and white, and color, and see if there is one only on the two sides, it seems dirty with pen ink

If they were the burned LEDs, as you say, it would also have the same defect from glass, could you also post the copy made from glass? Also because the white bar to be cleaned is under the glass.

Hello I did not post the copy from the glass because it is perfect, no problem.
I did clean the ADF inside glass as well. However, I thought that was just for the second side on a two-sided scan or copy.
Also the white place that lands on the slit glass when you close the top.
I think the scanner uses a different procedure if you are using the ADF / Slit Glass vs. the glass by itself. The scanner head slides across underneath across if you are using the glass. If it had a problem it would show on the glass copy I thought.

I don't think I've ever seen a burned out LED, they are very dependable. If it does it on 1 sided copies only from the ADF, clean the optics.

Ok, thank you for this. If no one else either has had an issue with the LEDs, then it almost has to be that.
I am thinking a person there might have been banging the machine due to an unrelated copy quality issue and maybe it did loosen some small pieces and they dropped onto the optics.
It may be a little while before I can get to this but I will report back.
Thanks to you and the others who contributed!

If the LEDs are used only as a light source and it still uses mirrors to project the image to a CCD scan sensor, you have a bit of lint or dust bunny on a mirror at a point near an edge where that portion of the mirror is only used when under the slit glass.

I appreciate that technical explanation.

I can't see the type of line very well, I don't know this model either, but on the HP, a similar problem, super clean glasses, scanning with thick, thin lines etc .... data bus was the problem.
I don't know if that sp c25sf is for communication between adf and the printer via data bus.


who knows right?

explained to you before, maybe you haven't read(?) Check what version of adf you have, try copying in duplex... I see in the manual that there is a version with double reading sensor☝️

Easy to test if traditional scanner or the one with a second scanner (usually mounted on the ADF side underneath):

- make a double sided copy of a single sheet with something on both pages, you will see how it's being printed.


For example, I've been easily fooled by a very small sized MFP when I was testing the single sided and the double sided scan profiles - new install. I was looking at the printer how it feed the paper but for the double sided profile it didn't turned the paper (I didn't checked the actual scan in the PC). I looked at under ADF quickly nothing obvious and then done a double sided copy and it proved is a dual scanner. I then identified the back side scanner was right in front of my eyes, can't forget that
