Canon CLC3200 out of focus copies.

You have to clear dc-con an put in data from list...That will solve the problem !

Thank you

But the problem here is bigger than you think.

I agree/ I would swap the Yellow Laser with the Black Laser
-because
Detecting/Correcting Color Displacement in Sub Scanning Direction
The Y pattern is used as the reference. The machine identifies the degree of color displacement
in sub scanning direction with reference to the timing at which other color patterns
are checked after a check on the Y pattern.
If the timing is not correct, the machine corrects the laser write start timing in sub scanning
direction.

In the iR C3200 it will not give a code for a SINGLE laser failure/ only if y m c k Laser motor fails E110

I'll try to swap Yellow laser with Black laser and i was ready to follow this procedure,but when i swaped Black laser with Magenta laser,or Cyan(i dont remember it),it showed me an error,therefore i stopped it.

Cassetes are full of paper .

Just to clearify something .
1-Black and white is perfect,the problem is only the color.

SWAP the Yellow with the Black Laser /

the only way a PG Test will not print = if Plain Paper is not set for picked cassette

COPIER>TEST>PG-PICK
Used to select output level during test print output.
Setting
1: Cassette 1
2: Cassette 2
3: Cassette 3
4: Cassette 4
5 to 6: Not used
7: Side deck
8: Manual feed


Your Assumed Checks
1. ITB unit was inspected & repaired. \/
2. ITB Drive unit repaired. \/
3. Have u swapped any Lasers ?
4. Did u >re-cam all laser units ??
5. Check the Pattern Reader Assembly
6. Have u checked the original DCON settings on log,against your P-print. ?
7. Checked all connectors on DC Controller ?
8. Have u checked>Adjust -Laser-PVE-OFST ?

Put some paper in first casette and wait for the tray to lift.

Tecket, if one laserunit is tilted in a way it doesn't beam straight down on the drum bit little to the left or right, u will get sub-scanning alignment problems. The adjustable lens cannot compensate for that.

I read the Technical Publication you gave me about ITB gears and all gears are changed like in Tech Pub.
How its possible i can't print in Copier-Test-PG-Test.
Tried all possible tests from 1-100 and nothing happens.(you must be sure i know how to do this).

What can cause this?

In fact i can not access C1 controller (i dont know the problem) to print a PS Test.

Controlling Synchronization in Main Scanning Direction
The control of synchronization in main scanning direction is based on the BD signal.

Controlling Synchronization in Sub Scanning Direction
• The synchronization in sub scanning direction is controlled with reference to the PTOP
signal (image formation start signal).
• When the mechanism becomes ready for image formation, the PTOP signal (image formation
start signal) is generated, turning on the individual lasers based on the signal

The machine uses the signal to generate the sub scanning direction signals (Y-TOP, MTOP,
C-TOP, K-TOP) for individual colors, and turns on the lasers of the corresponding colors

To correct the discrepancies in images, the machine executes corrective control for image
position; it detects displacement in color by forming a pattern of a specific color on the
transfer belt and reading it against the correct position.

Detecting displacement in color
• Forms an image position correction pattern on the transfer belt (direct transfer).
Reads the individual pattern (of different colors) using the pattern reader
photo sensors.
•Identifies displacement in color with reference to the pattern signals in the
DC controller.

Detecting/Correcting Color Displacement in Sub Scanning Direction
The Y pattern is used as the reference. The machine identifies the degree of color displacement
in sub scanning direction with reference to the timing at which other color patterns
are checked after a check on the Y pattern.
If the timing is not correct, the machine corrects the laser write start timing in sub scanning
direction.

When Replacing the DC Controller PCB
1) After replacing the DC controller PCB, use the following service mode to initialize the
memory of the DC controller PCB:
COPIER>FUNCTION>CLEAR>DC-CON
2) Enter the settings indicated on the service label using the following service mode:
COPIER>ADJUST>LASER>PVE-OFST
COPIER>ADJUST>FEED-ADJ>REGIST
COPIER>ADJUST>FEED-ADJ>ADJ-REFE
COPIER>ADJUST>CST-ADJ>MF-A4R
COPIER>ADJUST>CST-ADJ>MF-A6R
COPIER>ADJUST>CST-ADJ>MF-A4
3) Turn off and then on the main power switch.
4) Make the following selections in service mode: COPIER>FUNCTION>LASER>LADJ-
0.
5) Press the OK key. (The machine starts auto adjustment and will indicate ‘END’ at its
end.)

when u press for a PG6 , do u receive a message on control panel why it will not print/
so this means u can not print out the P Prints/User Data prints ALSO ??





C3200 C3220 Laser issues
Problems associated with the lasers.


Check the connections to the DC Controller. The Laser connectors are dove tail type. If the dove tails are not positioned in the groove, the connection to the DC Controller may be poor. Re-seat the connector by pressing the dove tails into the grooves while inserting the connector.

When i try Test Print PG1-PG16(i have tried these) nothing happens.No error,no code,no text ...nothing.
When i print P Prints,it prints them at the moment.
What can cause this Teckat?

what don't u believe/ just look at the posted print in first post/ this is not only a M Issue / it is all colors in sub scan/
Laser re-alignment is for MAIN SCAN Issues

U have to Pull out that ITB GEAR DRIVE UNIT on right side machine frame to inspect it/ u can not always view helical gear wear from the side

I don't believe it. I had such a problem with 3220. Reseated the lasers, reset the laser lens to home position. Tried other ITB assy, other patch sensor en reset dc-con several times. measured wiring of patch sensor. Eventually called Canon tech to replace dccon, but seemed that the M laser wasn't seated properly, so check the guides that hold the lasers in place.

Teckat,you must believe.I have clean all parts of it.
When i make a test of Laser in Service Mode,it shows NG!
There is no problem with codes i believe,because i found in the cover door old codes,restore them and still the same thing.
There are 3 things cause this : Lasers,boards,or firmware.
I can not prove anyone at this moment,because i dont have them.

The reason it pops a NG is because the Sub-Scan is not aligned to main scan

Post some PG6 AND PG10 Prints
SUB-SCAN ISSUES are usually not a Laser Issue- but a Mechanical problem

just re-looked at your first post with that image/ that is a SUB-SCAN ISSUE (PAPER FEED DIRECTION) YOUR MAIN SCAN IS NOT THE ISSUE HERE-

Both of these Machines have that ITB GEAR ASSBLY /ITB BELT DRIVE UNIT -Swing Guide gear unit-that craps out with stripped gears/u need to remove it -to inspect those helical gears
