CLC3200 color calibration problem

[goldencup]

Hi! i would like to ask how to calibrate color on CLC3200. May i know the step by step procedure? I have just replaced new developing unit and toner cartridge [each color]. I have cleaned the transfer blade and belt. I think my problem is on the adjustment. And by the way when i try to print on the top glass, the color copy quality is not good compare to when i use it as printer. what seems to be the problem? Hope you can give me some advice on this matter... Thank you very much!

if u have a Fiery {C1/C2} connected, u need to calibrate that first with a Kodak Gray Scale.

then calibrate the 3200 printer/see Below>>>>

You can recalibrate the machine when you notice irregularities in the color of the copy, such as when the copies turn out to be different from the original in gradation, density, or color.
The following two types of gradation adjustments can be made:
- Quick Adjustment
This is a quick and simple adjustment that is made to the gradation, density, and color
settings of the machine. Re-calibrations are made internally without outputting any test
prints.
-Full Adjustment
This is a precise recalibration that is made to the gradation, density, and color settings of
the machine. The procedure involves making test prints and placing them on the platen glass for scanning. Once this is complete, the machine automatically corrects the irregularities.
IMPORTANT
It is recommended that you select [Full Adjust] when performing an automatic gradation adjustment. Select [Quick Adjust] for a quick, but less complete adjustment between
regular full adjustment re-calibrations.
--------------------------------------
Quick Adjustment
1- Press (Additional Functions) [Adjustment/Cleaning] [Auto Gradation Adjustment].

Press [Start].
When the machine is finished adjusting the gradation settings, the message <Quick adjustment complete.> appears for approximately two seconds on the touch panel display.
Press [Done] repeatedly until the Basic Features screen appears.
------------------------------------------------------------------
Full Adjustment
IMPORTANT
• Make sure that you place the test prints properly. Accurate re-calibrations of the gradation,
density, and color settings of the machine cannot be made if the test prints are not scanned correctly.
• Three test prints are output by the machine during this adjustment. Make sure that a
sufficient supply of 11" x 17" or LTR of the selected paper type is loaded into the machine
before starting this procedure.
Press (Additional Functions) [Adjustment/Cleaning] [Auto Gradation Adjustment].
Select the Plain paper type for the gradation adjustment and then press [Full Adjust].
Press [Test Print 1].
TP1.JPG
The message <Printing...> appears, and Test Print 1 is printed.
Place the first test print on the platen glass.
Place the test print face down on the platen glass, with the black bands along the
top left back edge of the platen glass by the arrow.
Press [Start Scan].
TP2.JPG
The message <Scanning...> appears.
Remove the first test print from the platen glass press [Test Print 2].
Place the second test print on the platen glass.
Place the test print face down on the platen glass, with the black bands along the
top left back edge of the platen glass by the arrow.
Press [Start Scan].
Remove the second test print from the platen glass press [Test Print 3].
Place the third test print on the platen glass.
Place the test print face down on the platen glass, with the black bands along the
top left back edge of the platen glass by the arrow.
The message <Scanning...> appears.
When scanning is complete, the gradation adjustment begins. The message <Adjusting...> appears.
When the machine is finished adjusting the gradation settings, the message <Full Adjustment Complete.> appears for approximately two seconds on the touch panel display. The display returns to the Adjustment/Cleaning screen.
Remove the third test print from the platen glass ,press [Done] repeatedly until the Basic Features screen appears.

And by the way when i try to print on the top glass, the color copy quality is not good compare to when i use it as printer.

Use "Vivid Colors" when copying. Have many users swear by that setting.

I beg to differ with the idea that a Fiery calibration should be done first. The reasoning is if the measurement page is off then the fiery calibration will be off also. First calibrate the engine then the fiery to the engine.

Wrong- You always calibrate the Fiery first/
reason is, u choose the Rendering Style that applies to your customers views on what they need a document to look like / most companies choose between{ Photographic/or Presentation } there is a big difference in saturation and halftones- especially halftones in certain colors.

Read the imagePass C1 Color Guide.pdf and u will understand better.

[turkeyfoot]

I dont know, basically because I have no reference to post. BUT if the measurement page is off and then used to calibrate the fiery how in the world can the Fiery be calibrated. Im not finding a reference to anything in the pdf that contradicts what youre saying but neither does it say differently. Common sense reigns.

[teckat]

this has nothing to do with common sense/

what u do with the Fiery Calibration is to first establish parameters/

better yet -
customers who need to rely more on halftones use a densitometer , which light years over the Kodak gray scale

don't get hung up on the Auto-Gradation part/ that is mostly used for simple color balance/

when printing through Fiery- it's calibration & chosen Rendering Style supersedes the Printers Auto Cal-

[vigour]

We were always taught to do engine first, then Fiery.
I will experiment with your method.

This is a partial excerpt from a document on esupport

Please note the following:
* Be sure to turn Scan W/Unknown ID's to off after calibration is completed.
* Also, if you're not sure if there is something under user settings preventing you from performing the scan you can perform an MMI clear in service mode under Copier/Function/Clear/MMI, this will reset all user settings to default. If you perform the MMI clear you may need to reset service mode Copier - Option - Int-Face - Img-Cont to '3'. (Even though it still appears to be set at 3, other wise 'Check The TCP/IP' may appear at the bottom left of the display and the imagePass C1 and the C3200 will not communicate).
* If you are calibrating a copier version of the imageRUNNER C3200 be sure to perform a full autogradation using: Additional Functions - Adjustment Cleaning prior to calibrating the imagePASS C1.

Customer expectations documentation for the Advanced Color products show to calibrate the rip after gradation and shading correction. Available on E Support

All of that is Canon bullshit/

This isnt directed at any person only an attempt to provide useful information.

From ImagePass Color Guide page 2-2 on color calibration:
"When performing imagePASS-C1 calibration, you must perform copier/printer calibration with the Gradation Auto-Adjustment feature available from the Additional Functions menu on the copier/printer. The imagePASS-C1 calibration alone will not provide desirable printing output."
From 2-6: "The copier/printer offers the Gradation Auto-Adjustment feature, available from the control panel of the copier/printer. This feature has a "MAJOR" effect on printed color and "MUST" be performed "BEFORE" any ColorWise calibration."

WHY? Because the measurement page produced during the calibration is part of the calculated process, coming from a copier that hasnt had the gradation done it will be major league off. Another important factor is the maintenance of the mirrors on the scanner and needless to say - replacing drums and developers and itb components within the recc pm intervals.

Thanks to TEkcat for providing the pdf where this information was found. I was looking for the documentation. A lot of depth here on the boards! Keep it up.

[teckat]

that is a great guide,

one thing to remember,
when u deal with many Graphic Arts / & Design Firm customers 90% purchase & use a densitometer for calibration- if they see what they like - they don't even bother with AUTO CAL-

I always explain to customers when they need a Drum change, be forewarned that I will do an Auto-Cal - /Fiery Cal- and your colors will be off from previous day-

They then proceed to Remove calibration from Fiery, then do a Fiery Cal only-
these customers are Halftone Gradation Color Nuts

A Tech Tip- never go to a customer and just for the heck of it ,before u finish up,go run an AUTO CAL on the printer-with out asking first- this is a lesson I and others have well learned

[vigour]

I DO AGREE with you Mr Techat that calibrating with Densitometer does an amazing job because I have seen a Design Firm , that had a 3200 printer only model,( no scanner) produce some amazing results without being able to do auto grad.
Anyhow at some point after taking over service from Ikon they were unable to get good results, until I hooked up the scanner from their other 3200 and did an Autograd.
They didn't even know what an Autograd was.
These(Halftone Gradation Color Nuts) guys refused to buy 4080's because the output for them was not as good as 3200 .
