did u check if this issue is before transfer or after transfer

Transfer Bias/Separation Static Eliminator Bias Control
DC bias is applied to the transfer roller and static eliminator


BIAS =====DC Controller PCB

Primary Charging Bias Control
The machine is directly charged by the charging roller. DC bias and AC bias that stabilized
the charge is applied to the primary charging roller.

Constant voltage control of DC bias and AC bias
The DC bias and AC bias control circuits on the DC controller PCB control the DC bias and
AC bias applied to the primary charging roller to keep their voltage at the fixed level.
Developing Bias Control
The DC bias and AC bias are applied to the developing cylinder.

Primary Charging
Charging method Primary charging roller
AC bias constant voltage control: approx. 550 to 2600Vp-p
DC bias constant voltage control: approx. -400 to -800V
DC bias switch control (variable according to environment
sensor detection)

Developing
Developing Method= Dry one-component jumping development
AC bias constant voltage control: approx. 800Vp-p
DC bias control: approx. -300 to -700V
DC bias switch control (variable according to density
setting, environment sensor detection)

Does remind me of a main charge issue on a different brand.
not the same but similar, have you fixed this?
If so post the solution

on my experience it would have happened when we are using not genuine toner the possible cause the old toner and new toner mixing inside the developer, you only have to do is remove the toner and clean the developer unit and clean the mag roller. and try to initiallize it the new toner going to the developer.....and try to print more copy....

Yes. I like this solution too.

Even if it is an OEM toner cartridge, I've had endusers dump some other brand toner into the cartridge. Bring your vacuum and a know new, un-tampered with OEM toner cartridge. Vacuum out your new developing unit and re-fill the developing unit from that new cartridge. =^..^=

Thanks all for your responses. I was only able to get access to the printer Friday. Now the patterns appear on the top quater only. And you can see it on the drum and developer unit.

Does that mean that you won 't be attempting any of the suggested solutions? =^..^=

Re: Canon IR 2530 curvy line backgrounds

There is a pattern there,
I would think of the charge (primary) roller worn or contaminated.
try another drum unit to make a test.

Re: Canon IR 2530 curvy line backgrounds

There's a little leaf spring on the front side of the registration roller inside the right door of the machine, that if it's not making good contact with the roller and the frame of the machine can do really strange things to the image. Check it out....maybe save some time and $$.

Re: Canon IR 2530 curvy line backgrounds

Rudisemira, you have nailed it. I did that with a new toner and the background is gone but the prints is not as dark as it should. Perhaps the toner I used isn't ok also. I will try with another toner tomorow.
Thanks everybody.

Point to note;

On CQ issues many posters fail to note on their original post that product being used ( Toner and or Starter ) is not OEM.
There are customers who try to be on the Cheap , they create these CQ issues by not telling or showing tech products being used.
And there are customers who are fly by night techs ( I can repair anything ) people.

Good luck in your findings. 👌
