CS 3050ci image problems

[ClarkIR]

Hello again folks.

This machine has us thoroughly perplexed. Status pages, and other internal prints look excellent. SMB Scans look excellent. Copies and external prints are giving us image issues at the top of the page. The fill is poor.

We've done firmware, 906'd it, and a variety of the service steps in adjust/maintenance.

We were considering trying a 21 as a last ditch effort. Called in to help desk, awaiting their response as well.

any ideas?

Re: CS 3050ci image problems

Can you attach a sample ?

samples man!(hippie accent)

Which orientation is the paper coming out?

have you check the rollers on the transferbelt, are they detached?





samples!

Re: CS 3050ci image problems

ask and you shall receive.

again, the image is light on external prints and copies. Internal Prints and scans do not show any image issues. That even includes calibration sheets and color test pages.

Clean the optics.

Clean the optics.

First thing we did. Also tried replacing the lens in the scanning unit. And again, The image looks fine on a scan. Optics would affect the scan if it were the issue

Went back today, cleaned charge rollers in each drum unit, and cleaned the lasers underneath, did a 21, replaced all of the filters. No change. Here is a couple of print jobs I sent to the machine, it fades the edge facing away from you printing both longways and sideways. please see the attached.

here is the original document i printed, for a base-line

Have you tried printing or copying in mon color mode to see if it makes a difference when printing all cyan or all magenta or all yellow ( not that all yellow is easy to see anyway ). That might at least narrow the problem down some.

That particular original doesn't have bands of color that extend edge to edge ... like this:

Color Test Pattern LTR-R.JPGColor Test Pattern LTR.JPG

So I can't tell a lot. I can see that it's primarily cyan that is missing toward the bottom of your map images. Don't waste your time with U021. You'll just create hours of additional work trying to recover the image quality to where you are right now.

Have you done any color calibration, registration, toner curve? If yes, start with the cyan primary charge roller, then calibrate. If it's still bad, then the cyan developing unit, then calibrate. Try these originals. =^..^=

Re: CS 3050ci image problems

Here is that image blackcat gave me that I printed directly off a USB Stick.

We swapped the Cyan and Yellow Charge rollers, as well as the Black and Magenta ones, and still got this same result. So we feel confident its not the charge rollers.

It looks like the developers gone bad on both the cyan and black, thats my guess, if anyone has an alternate opinion, feel free to share.

I'd start with cyan. The black looks to be composite black ( M + C + Y all @ full coverage ). The black bar could still lack its cyan component and not be a lack of black development.

I'll agree.

If it was just missing cyan, the black band would be somewhere between brown and purple. I believe the black is bad too.

Don't forget the color calibration. =^..^=

Re: CS 3050ci image problems

question, wouldnt DLP effect both internal & external print?

Thats why we felt confidant it was only cyan. Because status page used only k and full color copy is combined image
