Mp3350 scan density calibrate?

Re: Mp3350 scan density calibrate?

Please note::: printing is perfect from PC any size and direction. Scan to email is perfect any size or direction. Thus if laser was shot it would be poor even on print. Also why would scan to email generate a good image if the doc feeder was warped?

guru?

Re: Mp3350 scan density calibrate?

just out of curiosity, it is free to try going and lifting the left front side of the scanner and then trying to scan or copy, WHY ARE YOU FIGHTING THIS KNOWN ISSUE?

Re: Mp3350 scan density calibrate?

Have you tried any of the suggestions given so far? You may have multiple problems. One causing a slight loss of image in the print density from a dirty shield glass but not enough to be noticeable during printing. Another causing a slight loss of scan density but not enough to be noticeable in scan to email. During copying, they add together to become noticeable.

Your original post did not say that printinng was good to all sizes and orientations. It only said print was good.

Direct from GG:

D017/D018/D019/D020

LIGHT/FADED IMAGE / COPIES MODE

PRINTS ARE OK BUT COPIES ARE LIGHT. REPLACE PCU

I have no explanation for the reason, But I've experienced it a couple of times myself, and the PCU was the issue - although in both cases it was overall light image quality, and not just one side or the other, but this is what I'd do

I have to agree on replacing the pcu and dev here, I have seen this quite a few times on this model. A page counter print looks fine, once copied it looses density. Are the counts for the PCU and dev near their yield?

Re: Mp3350 scan density calibrate?

Okay, all good ideas, but read this carefully all...

When we SCAN TO EMAIL, the image is fine, no defects. If we PRINT OUT a report, OR PRINT from PC it is fine. Only when SCAN TO COPY does the defect appear. Thus is if was a laser it would ALWAYS be bad, if the doc feeder was bent it would make problems scanning to email as well.

I understand this is a tough one, thus my request for help. Has ANYONE seen this?

Thanks

good idea, I think everyone assumed he already cleaned the optics, but given the way he is fighting the issue that has existed since the 1027 series, who knows????

Re: Mp3350 scan density calibrate?

I think you need to start from a fixed reference point.

1. Obtain some preprinted copier test charts with Black and White gray scale on at least two sides, preferrably all four. They are usually sold in packs of ten. Scan one to email and careefully compare the gray scales, especially the low end. If there is a difference no matter how slight, you have a minor scanning issue.
2. Now download a printable test chart with Black and White gray scale on at least two sides, preferrably all four. Print the test chart and compare the gray scales. Again if there is a difference, you have a printing problem.

One other thing, I always set the copier default to "Text" instead of "Text/Photo". This will tend to make the overall copy darker, especially if the original has slight differences in text density.

Have you replaced PCU and dev yet?

Re: Mp3350 scan density calibrate?

Please note everyone:

print is is perfect thus is can Not be pcu

Re: Mp3350 scan density calibrate?

Please note everyone:

print is is perfect thus is can Not be pcu

hate to have to tell you but it can be the pcu when print is fine and copies are too lite (but usually the entire copy is lite in that case)

Okay mate, I can read. I suggest you read what has been mentioned and try it. Replace PCU and dev together, clean optics and laser shield. If that does NOT get the copies perfect then it is time to look deeper.

Yes I know you say prints are fine but you have chosen to ignore what myself and others have suggested. As far as I can tell you have tried very little to get this fault resolved and if I were your customer I'd be expecting a quicker fix for such a minor problem.

PS It CAN be PCU and dev.

Ok logic logic out the window! I will try. I want blood if you are all giving me a line lol!

Haha, I know it defies what we all know about copies and prints but we are not trying to screw you over, like I said, I have had this most likely half a dozen times on these boxes. Best of luck and I hope it gets you and your customer out of the $h!+

Re: Mp3350 scan density calibrate?

After cleaning the optics change gamma settings SP4-918. They are defaulted to 15. I raise them to 18 or higher. Higher the number - Darker the image. Hope this helps.

Re: Mp3350 scan density calibrate?

Made density adjustment sp4918, cleaned laser and changed pcu. All good!

now I go beat head on wall!

thanks all!
