Motors are located inside the Laser Units, one motor for each colour. The Units can be opened very easily, just a few self-tapping screws.

After swopping lasers around this is what I get now, the yellow is off register, what does this mean.
Is the yellow laser in the yellow position [was in the cyan position] gone now.
It still won't run a color mismatch either.

Colour mismatch adjustment won't work until the defective Laser Unit is replaced. Part number for the replacement is FM3-5425-020.

Is there a way to swap a single laser or does this part only come as a pair of lasers. I'm just wondering if I can narrow down the exact part that is faulty in the laser component.

It has to be replaced as an assembly. Canon don't supply any separate components for these units.

ITB swap is just a quick 5 minute way to say "no thats not it"....looking at pg 10 it looks like laser outta whack as stated...kinda like the irc3200 when you have to mechanically re-cam the laser. Try to run COP/FUNC/CLEAR/REG-CLR,then FUNC/MISCP/AT-IMX,then ITB-INIT. Do auto correction in user mode. Otherwise put a new laser in it. Make sure that patch reader shutter isnt broken and just peeping out. Just a quick check. Probably looking at a laser. Cleaned the polygon mirror facets many times but never had one fail. Never tried to re-cam one of these

Hi Canuck,

Ran
(Service Level 2) COP/FUNC/CLEAR/REG-CLR

then
(Service Level 1) FUNC/MISCP/AT-IMG-X
this failed.

How do I do an auto correction in user mode? Does this mean auto correction from the standard menu?
Additional Function > Adjustment/Maintenance > Adjust Image Quality > Auto Correct Color Mismatch

Lastly Canuck you mentioned to check:
'Make sure that patch reader shutter isnt broken'

where is this located please

What I find very strange about it being a laser is, this machine has had very little use.
There are the total output figures from new. Why would a laser just go like this,
is this common?

112 Total (Black/Large) > 5713
113 Total (Black/Small) > 13317
122 Total (Full Color + Single Color/Large) > 33464
123 Total (Full Color + Single Color/Small) > 10651
501 Scan (Total 1) > 511
301 Print (Total 1) > 62862

Nothing is unbreakable
Nothing lasts forever.
I plugged in a brand new machine just out of the box, and the power supply exploded.

The Canon machine should do what it was purchased to do. This part should not
be defective at this point in time. Machines remember aren't living so can't be
compared to us human beings [ although some people give me doubts ]
Thanks for your help Vigour.

I agree Dan, I will go through this again now and see if this corrects it.

Hello malwatson

to help you out in future...

Have a look at the attached picture, this shows the internal breakdown of the laser units MY laser to Left BK C to right.
When you execute Color displacement correction control manually (Or the machine does at various times), it adjusts the mirrors by tilting them with a grub screw, per colour, so you may have an issue with say the cyan mirror, contained in the same unit as the black, consequently this will not affect the black as it is using a differnt mirror, it will continue to tilt / realign the mirrors based on the ID sensor OP obtained from straight and diagonal patches on the ITB, and the measurements between various points.....for a little more info have a read of the image stabalization pdf attached.

Hope this helps.

Point to note ...
Black is sometimes and usually fixed into position mostly on Ricoh products.

I think you meant to say the Lenses are tilted, not the mirror. There's only one Scanning Mirror for each pair of colours.

Thanks for that information Johny, I also noticed that on the cyan and black laser unit shown in your diagram that the cyan is on the right-hand side....is that right because the drums above are the opposite, the cyan drum is above bk correction motor and the black drum is above the cyan correction motor according to this diagram....from left to right on my machine the drum colors are as follows.

yellow, magenta, cyan, black and according to the diagram you attached the lasers are in the following order....magenta, yellow, black, cyan

All of these symptoms on previous models have been ITB related. Should we expect that this is not the first or primary cause now ? I don't.
Machines are made by Humans and so they are born with defective DNA too. But God made Humans and God is Perfect! This about that.

Hi have you tried a DC Con clear or swap cyan and mag drum over.
