Canon c5030i magenta problem

[Service@PRT]

Good morning!

Just wonder what happened with the machine..
Client called that light copy and a shadow on one side.

So when i check and print pg test 10 i got this.

I replace magenta coz i taught only drum problem but its the same.
The first one is before i change drum
And the 2nd one is after i change drum

Twice i calibrate with full adjust and twice with quick.. still same problem and there are still gap between magenta and black.

Thank you.

Looks like either the magenta drum or dev is not sitting correctly. I would take both out and put back in.

Agreed. Had the same issue with the pg10 looking similar to yours on a machine similar to that and the drum wasn't sitting correctly. Took it out, put it back in, and it squared right up.

In my scenario last week someone tightened developer with wrong type screw. There is pic ,something similiar (I don't know name of this screw,see atach).Devloper must move left /right when You installing/reinstalling drum.

After that inspect patch sensor(clean it) and inspect patch sensor shutter and solenoid.Sometimes shutter my be stuck.

At the end perform Auto correct color mismatch.

Done removing both.. after putting it back still same issue. I tried to change with cyan drum unit same issue.

Have you done the "auto color mismatch"

Yes... I might try to bring tomorrow one unit of developer and drum unit again from a working machine in the office and will see..

Re: Canon c5030i magenta problem

Found the problem with the light copy on one side.. its the laser itself.. too much humidity on it. My problem now is the gap between black and magenta.. brought new unit but still same problem

Remove the black drum & dev & reseat looks like it is not sitting correctly.

Yeah tried that also, but still.. i brought a whole new developing and drum from another machine including everything same model..( i mean includes the case of devs and drums 4) but the weird thing is the gap still there.. but the washout side is gone because already cleaned the laser from inside.

Even i brought new working developer and drum unit.. still same problem.. reseated thrice and no good result.. any other thing that can be done with this.


Thank you for all the input.

Re: Canon c5030i magenta problem

Like I mentioned earlier, I had the same problem with an IR C5255 copier a few years ago. The handling was to re-seat the drum and make sure it was physically straight in its place. But it sounds like you've done that many times over and still no luck.

I've never messed with the following service mode settings, but maybe you've got nothing to lose at this point.

I'm looking in a service manual of a slightly later model but might be the same for your copier:

COPIER > ADJUST > IMG-REG > REG-H-M (To adjust the write start position of M-color image in the horizontal scanning direction in increments of 1 pixel.) and REG-V-M.

Also maybe COPIER > FUNCTION > LASER > LD-ADJ-M. (When M-color skew volume in vertical direction is larger than estimation, the Skew Correction Motor (M) is locked, and color displacement cannot be corrected even when color displacement correction control is executed. This item places the Skew Correction Motor (M) to the center position in such cases.

Again, I've never messed with these so don't take my word for it. I'm not recommending you do this unless you study up on it and decide to do it. But this may be a tip that ends up helping you.

Good luck.
