color trouble

if you are not a tech it is going to be hard thing to do..
If you are a tech you need to pull transfer belt unit out ,remove belt and clean or replace the drive rollers inside the transfer belt unit.. that takes care of it most of the time if that is not it then the lasers or out of time and for sure you will need a tech..

color mis-reg in what axis?scan or sub-scan?Scan is path laser writes sub is scanner..if mis-reg in sub scan,yes clean itb belt and drives..if scan direction check open\close sensor for fixing\feeder drawer..you need a tech

[Copier_Guy]

You definitely need a tech. You could clear the M-CON and D-CON and that may get you through for a little while, but you more than likely need to totally replace the ITB assy. If that doesn't do the trick, the Lasers need to be Homed, which is not for the average novice to try to tackle.

You need to change the whole Transfer Belt Assy. Just changing the Transfer Belt will not do the trick. Cleaning the rollers on the Assy will not do the trick either. The whole assy needs to go.

Let us know how that works out.

sorry for the mistake i made
in taiwan when we say change the trasfer belt means to change
the whole assy,sorry....

and besides transfer belt assy and the laser,
i also change the 4 pc motor, but everything is the same
nothing changes
thanks for your concern.

3200 registration problem

run test print 6, (*28* test type 6), should be looking at a grid. also be aware as paper comes out reference to front to back of machine verses lead to trail on paper. if registration on lines that run front to back are off consistant front to back, then belt is slipping, if it is a laser alignment issue, lines will start off good front to back then get off, laser alignment that people talk about works with laser skew front to back,
when u cam itb assy in half to remove belt, make sure you clam both sides at same time, if u do front side, then back side or vise versa, u will warp unit, then belt will constantly track either towards front or back,
if u remove belt for any reason, i use wd-40 on the 2 drive rolers, both hard rubber, one approx size if pinky, other size of golf ball. and make sure if old belt goes back on that the inside of it was cleaned real good.
if u want to use a clear under function to help, try mmi.
if u cheat front door after first test print 6, then remove cleaning blade and run test print again, if it is belt slippage, u will see with out cleaning assy that there is less drag on belt, and issue looks better. if u start playing with lasrs, u may give yourself an additional problem. i have only replaced lasers because they quit.
hope this helps

Usually it is slipping of the transfer belt caused by soiling, pull out transfer assembly , remove belt and clean edges of belt with isoproply alcohol, also clean drive rollers. This is usually all that is required. I've seen bad laser as well,can switch from one color to another as diagnostic. Also may want to try DC-CON clear in service mode (print out data before clearing)

[Canuck]

Make sure that the pattern reader is mounted correctly...you lift this up when you remove the ITB assembly. Make sure it is seated correctly..its purpose is to read # patterns on ITB for color registration..you say it has to run for a while before it does it...hmmm..new ITB assembly?...I've had ITB drive gear go bad(on machine to drive ITB).. i wish i could see a sample

[Canuck]

i had one 3200 before that had color reg prolems..external secondary transfer roller(black foam roll in fixing\feeder drawer) was stiff to rotate...cleaned bushings,problem went away

[yourownfree]

I've had good luck just cleaning the ITB rollers if they are soiled with toner, then clear dc-con and reboot. make sure you have the latest firmware and software installed.
I've walked up and cleared DC-Con and rebooted and its fine copy and walked away with no problems. It all depends. I wouldn't clear mn-con if you dont have to, too much of a hassle. There might be be time you will need to.
if the color is good in the paper feed direction and not crossfeed and the operator side lines up but the rear side does not then replace the black laser.
also here is what Canon says:Problem........The colors are misregistered on the copies. Have replaced the ITB belt, cleaning blade and ITB drive motor assembly. Test print type 6 grid lines do not line up.
Solution
First run test copies of test print type 6 and output a P-print. Perform a DC con clear, turn off copier and re-cam all laser units. Cut all wire ties on the laser wire harness (purple wire harness). Turn on copier and input all DC con values from the P-print output. Perform an auto gradation and test with printing a Test print type 6.

I agree with mr kwazimoto its ITB unit problem just do wat told you and it will work

[11x17]

Do a quick auto grad adjustment. Not a full one but the quick one. I have resolved many with this adjustment

[Canuck]

What axis is the mis-registration...scan or sub scan..lets make sure we troubleshoot the right problem
