ir ADV C5035i - Toner Skewing - Cyan out of Register

Re: ir ADV C5035i - Toner Skewing - Cyan out of Register

Enter service mode level 2 > copier > function > laser select LD-ADJ-C press ok, open and close the toner door during operation.

Run LD-ADJ-C once more leaving the door closed.

Run auto color mismatch.

Thanks Skynet for responding so soon, its definitely the toner door and not the drum door is it.
I did what you said and I opened the toner door during the LD-ADJ-C operation and then I ran that operation again with the door closed. Ran the auto color mismatch and it still doesn't complete the auto color mismatch process and I still have the same problem.

You could try swapping the two Laser units over (they're identical) and see if the mis-registration transfers to another colour (probably yellow). At least then you'll know for certain that you're dealing with a Laser problem.

When I go to Alarm2 I can see the following code when I try to run the auto color mismatch function.

See attached below

Just to be sure are these the lasers you think I should swap over?
I know they are the same and emit the same light, but just to be sure this is what you are suggesting.

Swap Green (original cyan lasers) swap with Red (original yellow lasers)

No, the Laser Units are below the Process Unit. There's one unit for Yellow & Magenta and another for Cyan & Black, each unit containing two Lasers. You need to remove the Process Unit to gain access.

Are they contained in the Black unit shown here and if so, which screws should I remove for the procedure please Dan.

You're swapping these two units over (see attached pic).

Remove the Process Unit First. I think it's attached to the rails with 2 screws either side, if I remember correctly.

Yes, those are the Laser Units. Removing the right-hand unit should be straightforward. To remove the left-hand unit, you have to remove the left panel and move a fan out of the way. Refer to the Service Manual for the full procedure.

Yes I see that, before I start there is a large label with a big do not swap lasers over symbol on it, should I still proceed.

I can see that the two laser units are identical and I will be putting them back in the correct order, can anyone enlighten me why that label stating 'don't do this' would be there

I've never seen that warning label. I've swapped the Laser Units before without any problems when diagnosing faults, and the units are identical.

Dan after swapping the lasers over, the yellow is off register now as you predicted. But the cyan isn't perfect either. See attached.

I have had this twice now where ,as discussed , Level 2 service mode laser adjust ala CLC4040 has solved it.

I would try this again before ordering the offending laser.

Hi CanonSco,

[Level 2 service mode laser adjust ala CLC4040 has solved it.]

I'm not sure what you mean sorry, do you mean this?:

Service level 2 > Function > Laser > LD-ADJ-C > Click Ok
Open 'Insert New Toner Entry Door' Close it

Run again
Service level 2 > Function > Laser > LD-ADJ-C > Click Ok

Try color mismatch.......

I tried this on all lasers and its still the same

Re: ir ADV C5035i - Toner Skewing - Cyan out of Register

The Laser Units have Skew Correction Motors for each colour (see attached). Running LD-ADJ should operate the corresponding motor to correct skew, but for some reason one of the motors in your defective unit isn't operating. You could try running LD-ADJ-Y this time to see if it has any effect, if not try moving the motor by hand in case it's stuck.

I wouldn't worry about the Cyan being slightly out since swopping Laser Units. That will be corrected by auto mismatch adjustment after you've corrected/replaced the other Laser Unit.

Hi Dan,

Thanks again for your amazing input, can you tell me please where the motors are located as your image is cropped, thanks very much.
I would like to see if they are stuck.
