Run PG 10 test print to isolate bad drum.
Practice makes perfect
If it ain't broke, don't fix it
A picture is worth a thousand words
If you want something done right, you have to do it yourself
=================================================

While Line
If a white line is found in a specific color, suspect a fault in the development system, transfer system and drum of that particular color.
16-Gradation (TYPE=4)
If a white line is found in the image, suspect a fault in the developing system.
Full Page Halftone (TYPE=5) run single color *
White Line
If a white line occurs, suspect a fault in the ITB unit, secondary transfer outside roller, or laser exposure system.*- You can print out test prints for individual colors by making the following selections in service mode: COPIER>TEST>PG and then COLOR-Y/M/C/K.
*- You can also change the density of the test prints by making the following selections in service mode: TEST>PG>DENS>Y/M/C/K.
Points to Note When Removing Drum Unit
When removing the drum unit, make sure that the shutter lever is at the 'Unlock' position.
If removing the drum unit from the host machine while the shutter lever is not at the 'Unlock' position, and then mounting the unit again after shifting the lever to the 'Unlock' position, the shutter of the drum unit is not opened properly.
Therefore, toner does not get into the drum unit from the hopper assembly, and the spilled toner strays within the host machine. If removing the drum unit from the host machine while the shutter lever is not at the 'Unlock' position, put the unit back and shift the shutter lever to the 'Unlock' position, and then, remove the unit.

Dirt can get inside the laser and cause lines. I would clean the laser before dismantling the drum unless there are obvious lines on the yellow drum surface.
When you think you have made a procedure idiot proof your company employs a better idiot.

2TR-CLN = Secondary transfer roller cleaning
This is for the bias cleaning of the secondary transfer roller.
It is used when the sheets are stained or smudged by dirt in the secondary transfer roller toner.
TNR-COAT = Secondary transfer outer roller toner application mode
When the right door is closed while the secondary transfer roller is not dirty (when a new roller is used), the substance on the secondary transfer roller surfaces rubs against the ITB and becomes adhered to it, leaving areas of the images white where the substance was rubbed onto the ITB.
In order to remove this adhered substance, toner is transferred once to the secondary transfer outer roller, and then the secondary transfer outer roller is cleaned.
This is used when the secondary transfer roller has been replaced with a new one.

Hi ,
I saw a similar issue and the root cause was the charge roller contamination in Drum unit . It seems that in some countries Canon asks to clean the charge roller to fix the issue before to replace the drum units to fix the issue .
