After removing OPC Drum, Should I clean the Developer & PCR Roller? -- Laser Cartridge Q2612A

[Roark1]

After removing the OPC Drum, should I clean the Black Developer [Mag] Roller & PCR Roller,  in Laser Cartridge Q2612A?

The reason I ask is: I see a lot of black toner powder on the roller touching the blade : Is this just 1] waste toner, needing to be cleaned up?;

or 2] or is toner powder to leaking out of the supply chamber? & I will be causing more leakage by trying to clean it up?

Should I clean BOTH rollers? & How thoroughly?

I'm still not sure which black roller is the Developer Roller & which is the PCR Roller.

I opened the Cartridge to clean  & removed the blue OPC Drum to remove debris caght in the  [wiper?] blade.

Using 91% alcohol & I'm being careful not to touch the OPC Drum opr expose it to light.

There are many of them on YouTube if you like.

Just google "hp q2612a refill" you will find as many as you want.

I'm adding these questions to my original post:

I’m reinstalling the OPC Drum,but I can’t seem to shake out all the toner powder from the cartridge;

It’s probably coming from the supply chamber via the doctor blade & mag roller gap ; or from maybe the waste bin.

This means that l always end up with toner on the PCR roller, mag roller & toner smeared on The OPC Drum when I try to reinstall the OPC Drum.

Where is this  toner powder coming from? or  Maybe it's not crucial to remove all the toner powder--Does anybody know?

I have looked at the videos suggested by East2100 on YouTube ,but most are in Hindi; & the others don't answer my questions.

 I see a lot of black toner powder on the roller touching the blade :

Is this just 1] waste toner, needing to be cleaned up?;

or 2] or is toner powder to leaking out of the supply chamber? & I will be causing more leakage by trying to clean it up?

We rebuild toner cartridges and all cartridges are assembled before any toner is added. You will have toner leakage and depending on the age of the cartridge the Dr. blade or cleaning blade could be damaged, in which case you will always have toner leaking out a spoiling prints.

Thanks for your reply! I had no problem with  toner leaking out & spoiling prints! & there is no reason to believe that the Dr. blade or cleaning blade would be damaged form my just removing the drum.

My question is just: How important is it to remove all toner from the PCR roller, mag roller & The OPC Drum when I try to reinstall the OPC Drum? since I can't seem to avoid getting some toner on them when  I reinstall the OPC Drum

The toner is always there somewhere and it's no necessary to clean every bit of it.

The cartridge will clean itself if it's not then it could be defective needed to be replaced.

The most important thing may be that the cartridge is cheap enough and even lower than $7 so spent so much time on it is not worthy.
