IRC 3200 Copy and Scan Quality Issues

[kevin2008]

I Have changed out drums (all colors) Transfer assembly and cleaning blade and still having copy quality issues. Having lines in copy only, and very bad quality scans.

I full calabrate in user menu and printing is OK.

If your only having light copies from the reader section then you should check the reader section.
Optics,white plate,lamp,ETC. Your problem is in your reader assy. That would be a good place to start.

i 'm sorry, bad section please move to technical section. thank

Stupid question,, but I have to ask it,, it has been a rough day

Have you run auto gradation?,,, I would recommend running CCD-Adj first though in service mode.

Yes i run auto gradation, and reboot the machine.

Pb is not fixed.

Thank you

You mentioned that you cleaned the lamp,, Screwtape suggested replacing the lamp. You said you ran auto-gradation, but did you do the CCD-ADJ under service mode first? Are you aware of what the white plate is? It sets up the optics during the bootup procedure to tell the reader what the white reference is for scanning, if it is dirty, the white balance calculations will be screwed up in the reader.

A few years ago, we had a new install of an iR C5180 with the same issue: good prints, bad scans and copies.

(Actually, the prints were off a bit, too, after running Gradation Auto Adjust.)

Is the scanner slamming when it comes into the home position? Ours was. Turned out that the black strip that's attached to the scanner to trip the home position sensor had fallen off, and was sitting nicely in the scanner "cavity". A few drops of superglue and life was good again.

Strange that it never threw an error code, but it didn't.

[kevin2008]

thank you to answer you yes I made CCC ADJ and then the auto gradation.

I do not have the lamp of replacement to test, however it ignites well, and I cleaned it.

Then I will test dismount to still clean the white plate with the top of the lamp.

Yes I believe that it is not placed well.

Perhaps there are also sensors to clean too?

hello and thank you,
I still will dismount to check, I does not hear slappings when the machine ignites, but the SH-PS-ST is very long 5 minutes.
Perhaps that the problem

If the standard white plate on the underside of the platen glass is dirty, it can't be adjusted correctly. Always clean the white plate first. If NG is displayed, check the items below, and redo adjustment. Is the platen glass attached normally? Is the standard white plate attached to the platen glass a correct type? Shading correction adjustment takes between 5 and 180 seconds.

Under Copier/Adjust/CCD there are these adjustments that must be perform as well. If you look at the glass on the upper right side there is a bar code with some numbers. They should match these white plate adjustment values
W-PLT-X
W-PLT-Y
W-PLT-Z

If you have cleared the reader controller PCB's RAM or replaced the reader controller PCB, re-enter the values.
If your CCD adjustment perform okay then you don't have a problem with the CCD. If it came up with NG! then you would have a bad CCD.

I would make sure all values for R-con are entered correctly. That image looks a bit choppy. You might even have a problem with the R-con PCB.

Hello and still thank you for your assistance.

Today I have to dismount all the part out of glass for all to clean and still the cap of CCC and I have to check all the cables. The white plate is clean is well fixed on the pane.

I have to also clean the lamp and it does not have a yellow or black trace, and the small wire on length is not cut

I also checked the values as on the code bar of the pane.

W-PLT-X = XXXX
W-PLT there = XXXX
W-PLT-Z = XXXX
TEST-LAMP = OK

on the CCD is written:
CCU-RB = 0
CCU-RG=-2

then I entered this value into the body in level 1 and the result is:

CCD-ADJ ok!
SH-PS-ST NG!

I printed the MISC-P by safety and I will try tomorrow the FACTORY clean RAM, I think that it is the last chance.

Do you think that is good? Is it necessary to print another thing for the safety of the values of the machine?

Greetings

PS: have you an safe paper of MISC-P of a machine IRC3200 which functions to send to me by email?
