CLC-5151 prints -- but needs adjustment/ calibration

[Mzungu]

Hi folks,

Here in Tanzania I am on my own with this device. Toner and drums are renewed, H1 is in the network, it scans, but greets me with this print:
1.jpg

To better understand the coordination I put on an InDesign A4 page in the middle vertical a thin black, cyan, magenta and yellow line with no gaps. Then I copied and rotated that line by 90deg. In the scan I present here I drew a vertical line with a blue pen to show the vertical centre where all line where supposed to be.

This scan confirms what is also notable from scan1: the respective colours deviate to the right horizontally. Vertically all seems correct.

How can I fix that please?

I compared all values set in service mode 2 [*,2,8,*] with the ones on the print-out I got when I bought the machine = all correct.

@ Admin: please delete the second post, thx.

Re: CLC-5151 prints -- but needs adjustment/ calibration

Did you make a basic things like calibration,full gradation....

Re: CLC-5151 prints -- but needs adjustment/ calibration

U need to clean/refurbish your ITB. Pull out the right side drawer, remove the cover above it. Open the front cover, lower to blue handle. Now u can slide out your itb unit.



U need to remove it's belt carefully and clean all the rollers inside, also clean the inside of the belt. Better is to replace the belt.

The gradiation failed due to the fact that the print which had to be scanned/copied-in again was not recognised by the system. Obviously deviation was to great.

Re: CLC-5151 prints -- but needs adjustment/ calibration

Do as "fer" says he is 100% correct, the belt slips usually because of leaking black toner. Remove & clean the ITB drive roller AND inside the ITB belt.

Then perform auto gradation.

Hi to all,

I would start by cleaning the color displacement sensors (see the attachment) and proceed to execute the " automatque color displacement correction" in user mode.

First print out a PG6 in service mode

this will show issues for image shift in Paper feed (sub-scan) and or Cross feed main scan) or both issues--

---------------------------------------------
One note to point out/ in this model series u can do a Laser Tilt Adj without removing Lasers-
go>>>>>>>to

Service Mode Level 1
1-Press the asterisk key "*" (add func)
on the control panel.
2-Press the 2 and 8 keys of the keypad at the same time.
3-Press the asterisk key "*" (add func)
on the control panel again.
u need to go into LEVEL 2 of service modewhile in Level 1> hit the (*)(2key again)
for Level 2
------------------------------
in Level 2 go to>>>>>>
COPIER>FUNCTION>LASER
LD-ADJ-Y/M/C
Making the tilt correction motor return to the initial position automatically.
Operating Instructions
1) Select this mode.
2) Press the OK key.
- The operation starts. It automatically stops when it is completed.
Reference:
The tilt correction motor may get locked when the tilt amount in the horizontal scanning direction exceeds the expected
range, and consequently color displacement cannot be corrected even though automatic registration is conducted.
When this symptom occurs, use this mode to make the tilt correction motor return to the center position automatically.
(If you try to do this operation manually by opening the scanner unit, you may touch the lens. For this reason, be sure todo it by the automatic operation.)
This Service Mode is used to correct the tilt of Y, M, and C against BK, which is used as a reference, when the tilt islarge (when the horizontal lines are higher at the right).

Thank You! Replacing the ITB did it.

After replacing the ITB the print looks like this:

ScanImage001.jpg
We are moving forward

Next the colours have to be adjusted/ calibrated. I am not sure if it requires Teckat's way, as there is not tilt or displacement anymore.

Better ask the geeks again -- what would you propose please?

READ HERE/ u calibrate the Printer first using Auto Full / then the Fiery Server (if present) on the Fiery Server u can use Kodak Grey Scale or an expensive Densitometer

this is what the Kodak card looks like below

Re: Thank You! Replacing the ITB did it.

Wow You are really The Man!

I have the Kodak Gray Scale exactly like this and the Kodak Color Control Patches too
[/QUOTE]

Now the snag:There are options

1. Press * > Adjustment > Cleaning > Auto Gradation Adjustment > Plain > Full Adjust > Test Print 1 => its printing a 4-row grey scale. HOWEVER I PUT IT ON THE PLATEN ITS NOT ACCEPTED.
2. PRINTER > SETTINGS > FUNCTIONS > Calibration > Calibrate => its printing a ColorCal Measurement Page. Along the top edge the Kodak Grey Scale is put on the scanner/ platen. NOT ACCEPTED.
3. Command WorkStation5 > launch Calibrator > 1. ColorCal, 2. Plain Paper, 3. Generate Measurement Page => "Error printing the M.Page. Check your printing device. Java errors:

[11006]: STR_DATASRV_COMMAND_FAILED

[21208]: STR_FLAMAPI_COLR_INVALID_CLASS

I managed though to print from InDesign the page with the thin KCMY-lines. The black is almost perfectly centred (-1mm), the cyan derives another 1mm to the right, magenta hardly, yellow invisible.

Occasional message on the bottom of the touch screen:
The Default Key is corrupted or invalid.

I already tried to take-out preferences and reset them via > *, 1+7,9+3,* no result

Re: CLC-5151 prints -- but needs adjustment/ calibration

Default Key is corrupted or invalid =fix--

How to clear out the message Default Key is Corrupt
1. Enter service mode * 2 8 * > * 2, for entry to Level 2
2. Copier > Function > Clear > highlight CA Key - press OK.
3. Power copier off, then back on - Default Key is Corrupt message should clear.
--------------------------------------------------------------------

If the message did not clear perform the following to create a new key:

1. Additional Function> System Settings> Network Settings> TCP/IP Settings> Certificate Settings 2. Select Generate Key
3. Enter Key Name: input any name (Default Key)
4. Select 1024 for Key Length
5. Enter the Current Date as the start date
6. Enter the End Date with current Month and Day and the Year - 2032
7. Select Start Key Generation
8. Go back to Certificate Settings and select Key and Certificate List
9. Select the corrupt Default Key and press Erase
10. Cycle power.
---------------------------------------------------------------------------------------


If Dept. ID mode is enabled on the copier, the scan function may be turned off in the following Dept. ID set up mode:
Additional Functions - System Settings - Dept. ID Management - Register ID/Password - Scan = Off, resulting in 'Measurement Page Not Detected' being displayed when trying to scan the measurement page with the gray scale. If this is the case, you can enable scanning w/unknown ID's for calibration purposes with the following setting:

* Additional Functions - System Settings - Dept. ID Management - Accept Scan Jobs W/Unknown ID's =ON
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
--------------------------------------------------------------------------

if this is not your case>>>>>see below

First >> in PRINTER > SETTINGS > FUNCTIONS > Calibration --- find & select "Remove Calibration" then>>Try setting IP port filtering to yes and make sure all ports are enabled. Re-boot the fiery and print a configuration page to verify the changes that you've made. This should open all ports on the fiery and allow the calibration scan to go through. next-------Try placing the calibration measurement page on the glass in LetterR direction with the Kodak gray scale placed in the position indicated on the measurement page. Now on glass calibration-----------

Auto Gradation Adjustment > Plain > Full Adjust > Test Print 1
when u look at this page do the color scales line up ???
what direction do u place on glass ??

Re: CLC-5151 prints -- but needs adjustment/ calibration

1. Enter service mode * 2 8 * > * 2, for entry to Level 2
2. Copier > Function > Clear > highlight CA Key - press OK.

This function is not listed.But I generated a new key:Additional Function> System Settings> Network Settings> TCP/IP Settings> Certificate Settings 2. Select Generate Key problem solved!

If Dept. ID mode is enabled on the copier

Dept. ID mode was off and stays off

* Also, if you're not sure if there is something under user settings preventing you from performing the scan

I can scan via Fiery Remote Scan, so I am NOT "prevented". This is how the print looks like I gain from: * > Adjustment > Cleaning > Auto Gradation Adjustment > Plain > Full Adjust > Test Print 1
Untitled.jpg
As the colour scales are hardly visible, just an idea of magenta, maybe its not identified? problem persists

Auto Gradation Adjustment > Plain > Full Adjust > Test Print 1
when u look at this page do the color scales line up ???
what direction do u place on glass ??

The red arrow I added on the scan is the upper left corner (zero corner) of the scanner, the scales are of course face down so that they can be scanned.

[Mzungu]

Update:

Why don't we do the calibration with the eye?

1. Scanning the 2 Kodak scales
2. Printing the scan
3. Scanning the print.

It looks like this:

Before changing the ITB the colours had good intensity. Now there is almost none except of a small smearing across the paper.

Re: CLC-5151 prints -- but needs adjustment/ calibration

printer will not calibrate test prints because there are no color patches to read/

u need to look at that ITB UNIT/
run some PG10 TEST PRINTS

see example of PG10
pg10.JPG

Re: CLC-5151 prints -- but needs adjustment/ calibration

Not sure how to do this, you gave the Service Bulletin about "Color Shifts caused by the printer (horizontal lines out of registration)" = PG-Type 6. Would you explain PG10 please?

To see the difference I put the old ITB back looking like this:
ITB old.jpg

remember, the new ITB was like that:
ScanImage001.jpg

so either I have right geometry but no colours or good colours placed out of order

This lets me conclude that the ITBs are the cause. If it can be fixed by adjustment I shall try it!

Thanks for all the help btw.
