iR C3220 full auto gradation adjustment problem

[Guest]

while trying to perform full auto gradation adjustment

the machine will print out the 1st test print

same procedure, I place the first test print face down on the platen glass
with the black bands to the back.

but when I press the start scan, this error message will come out

Correctly place the test print on the platen glass.

any ideas?

thanks!

is there a color displacement?sometimes it cause these problem.

nope, the test print was actually quite nice. but when i i tried to photocopy color, the color would be off so i tried to do an auto gradation.

[smiley]

have you clean the reader unit?

Try auto gradation from a different paper tray. If the message clears, check the tray alignment of the paper tray that failed. Correct the alignment of the tray if needed. If message does not clear, run a P-Print and perform an RCON clear. Then load RCON back in from P-print

Check your ADJ-XY values on the sheet that's on the door.
Make sure those are set up correctly. Tried doing a CCD adjust as well.

Hi guys, been quite busy...I put the machine on 1 side first because we got a lot of pending machines .
so far here is the blow by blow account.

@smiley: tried to clean the reader unit, optical area
result : failed

@teckat: tried on a different tray - failed
print p-print, clear rcon, keyin configs - failed
clear controller ram - keyin configs - failed
format HDD, reinstall system softwares - failed

@smiley: yup, ADJ-XY is ok,
alignment is pretty good. I've done the CCD as well
but still no luck.

but i clean 1st the optic before i do ccd adjustment.its just be at the optics nothing to do with the printer unit.why dont you try printer ram clear at factory mode.and run auto grad after it.

ok! here is the fix=
your test print from auto gradation registration is off a bit/ look at that print ,the CCD must read the correct pattern position from it =could be cross-feed or paper feed issue/if that auto gradation print image is shifted it wont scan right ,check if your ITB assembly belt is probably shifting a bit / check that Grid test print> PG6

also try this= move the test print down a little from top of glass/see what happens

[smiley]

i agree with teckat.try to do a pg print type 10 and look if there is a dispacement in colors.it happens to me many times i try to auto grad in the machine that has acolor displacement problem.try to clean your itb.use citrus oil.it realy works.

To add to what the other guys have offered,,, initiate an auto gradation on another machine, and compare the page from the working copier to an auto gradation page from your problem child to get an idea where the problem lies. You can "candle" the prints to see what the displacement is all about. be sure to label the good one to eliminate confusion later...

I already checked the grid test, and the print alignment was ok.
I also tried moving my test print up / down / left / right on the top glass little by little
just to check if it's really something about the alignment.
still got error

type 10? isn't this for testing color density?

I compared the two test page, and alignment was not with each other was not that perfect (only little bit) what I did was, I tried the test page from the ok machine and use it for the auto gradation scanning. guess what...still failed

I am thinking of replacing the CCD later...
still open for suggestions
really thanks!

Got this from Canon Navi,

Problem :
When trying to run the Auto gradation adjustment the display repeatedly states " reposition the original".


Solution :
In this instance after the Reader controller and the IF board had been replaced and the problem still existed replacing the ribbon cable (FH2-6983-000) that connects the two boards fixed the problem.

here are two stupid questions ??
did u look to see if your lamp is staying on through the test scan ?
is the scanner moving forward ??

do u have an image pass on this machine/
if so have u tried a calibration from Firey/w Kodak Grey scale ?

just to add why would replace the CCD/ if you can print off the glass with no errors and no CQ issues ?
