Canon Color iR 3220 error code E000020-0325

Hello. We are having an issue with our copier and would appreciate any help. I have tried to find a list of error codes but have had no luck. The copier was leaving a line of yellow on some pages, and then it got worse and there were wide streaks of multiple colors. We switched the drums, and when we restarted the copier, it said is was "adjusting gradation", and then it gave us this error code, and said to restart, but it just keeps repeating the same error. Also, there was a lot of toner of different colors on the roller after this and it wasn't doing that before we changed the drums.
Thanks!

The 3 in the subcode(0325) points to an issue with the cyan drum unit.
It sounds as though prior to changing the old drums they may have dumped toner through the machine...the yellow background that you had is a giveaway.
The multiple colors on the page could be the cleaning assembly being overwhelmed from the drums dumping....one screw and out comes the cleaning assembly and wipe the blade with a clean cloth.
Sadly i think it's past the stage for you as a machine owner to service...time to call a tech.
The ITB assembly needs to be looked at ...if the toner dumped through the machine the assembly needs to come out and be washed up to avoid color registration issues.For that particular subcode the SALT sensor needs to be wiped clean with a cloth.
It's an easy fix but you really need a tech to look at the machine just for a clean up to ensure no problems remain from the old drums dumping through the machine.
