first off> u have a paper feed registration issue> enlarge document to see issue

Perform in LEVEL 2 > COPIER> FUNCTION> CLEAR> REG
power off/on printer--then>Clean the patch sensors and perform an auto color correction mismatch ( corrects Color Registration issues)> then run a full auto gradation>
To perform an auto color correction mismatch, Enter Additional Functions Adjustments and Cleaning. On page three select auto color mismatch correction.
If Auto color correction mismatch is not an option, be sure to update the firmware to the latest version. To clean the patch sensors manually actuate the solenoid to open the shutters and wipe the sensors with a dry lint free cloth.
Below is a photo of the solenoid and shutters that cover the sensors.

Re: Need Help: iRC3380 Correction of faulty images

When the drums get used, they have a tendency to loose toner that will drop on the laser procting glasses. This may result on a poor print quality or E020 error code. Use the laser cleaning tool or take out the laser and clean it.

Good luck.

Yes sirr...I replace both black n yellow assembly from other machine n the pattern just fine.This prove that this is the problem with the assembly n not the machine itself. Been having this problem for 2week n we could not fix it n we got no choice to call a real Canon TechSorry sir becoz my English is bad

Bad OEM Units can be returned for credit / service tech can't repair them

Re: Need Help: iRC3380 Correction of faulty images

Hi All,
This symptom happens very often on iRC3380 series.
The reason is seal that locate under drum (prevent waste toner in drum unit from come out),
it easily come out if technician rotate drum wrong direction and then it will block laser shine on drum surface.
As in result, you will have printout like attached file early.
Replace whole drum unit will resolve problem, however that way is costly.
The best solution is to reinstall that seal properly.

Hi sir...
thank for the info....
just to make sure...

The seal that you mention is it the one that attached together with the waste toner unit which look a bit plastic transparency
like?

if this is it.....
i did change the said item using another assembly unit n it still the same...
The Developing carrier is the only thing i haven't change because i couldn't find it on the market... everybody selling the whole drum unit...
