Canon CLC3200 out of focus copies.

[tinnyjay]

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?

[Fer]

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.

[teckat]

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.)

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.

Cassetes are full of paper .

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

I agree/ I would swap the Yellow Laser with the Black Laser
-because

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

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 ?

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.

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.

[Fer]

Is the drum drive in this machine a belt type, maybe the M drum isn;t properly driven, by for example drive belt not tight enough?

Explain how DCON CLR will help this SUB-SCAN ISSUE ????? IMAGE BELOW

Your gonna have to clock those lasers CMYK manually back to home position. The tech pub is floating around there some where in the forum. Normally I check for the service mode record, print out a P-print, clear DC_con> shut down> remove lasers> adjust lasers manually> install lasers back>reboot machine and leave the front door open>renter the values using the service mode record that came with the machine>shut down then close the door>reboot.

Your firmware could be corrupted as well.
DCON can be corrupted as well.

there is a fine adjustment u can manually make on the Laser units/ u roll each on all the way , one tooth shy on each/ put them back/ & re boot

Laser Cam Out-of-
Alignment Condition due to loose wiring on the DC Controller/System Controller or loose
interconnections (two ribbon cables) between the DC Controller and the System Controller:
To determine if the DC Controller/System Controller wiring is possibly at fault, go into Service Mode and
perform a PG Type 6 and then a PG Type 10.

To determine if the laser cam/s are at fault, go into Service Mode and perform a PG Type 6 and then a PG
Type 10.
1.Remove the 4 laser units from the machine.
2.Remove the laser cover to expose the lens.
3.Adjust the cammed gear until it is at its center position.
5.Turn on the power and once again try PG Type 6 and PG Type 10.

Check for a stiff turning secondary external transfer roll.....seems everything else mechanical checked. Cam the lasers,etc. I've had a couple 3200's that i had to clear the main controller RAM...do your p-print,etc,back up the service counters,clear all the RAM,flash the machine with newest firmware. This is the first thing tech support will tell you to do. Eliminate the firmware/corruption possibility...only takes about 15 min for everything. Are the initial samples scans or prints? Like teckat said,not a scan issue...sub-scan issue

Teckat,seems to be a mechanical problem as you say.
I printed a PG10 and after following your advice,i swapped lasers and checked the gear on the laser unit and after some tries,i centered yellow and cyan laser..Now i have to work on black and magenta laser,because black goes a little over yellow and magenta goes a little over cyan color.Tomorrow i'll show other results.
Thank you so much
