Drum unit scratches

[Ernesto Castro]

Hey, I guess I messed up... trying to remove some toner sticked to the developer unit drum, I created very very minor scratches and now I have some deffects on my prints.

I have a Toshiba AC5005.

Is there anything I can do in order to fix this? I was thinking as last resort to replace with an Amazon "generic" developer unit (like some published as T-FC415 TFC415 Developer Kit, Compatible for Toshiba 2000AC 2500A 2505AC 3005AC 3505AC 4505AC 5005AC 2010AC 2510AC 2515AC 3015AC 3515AC 4515AC 5015AC Printers Cyan*1).

Any other alternative? I was thinking using a very fine lenses scratch remover I have, but I'm quite sure I will make the problem worse.

Any suggestions would be greatly appreciated!

Unfortunately, you'll need to replace the drum. I've never seen any product work for removing a scratch on the drum coating. The part number for that is: 6LJ70598000 (for the C, M, or Y units) and: 6LK49015000 for the K (black) unit. Replacing the drum is an easy job and much cheaper than replacing the entire image unit.

Thanks! I'll do that, $70 is not a lot... I though I was looking to a several hundreds mistake!

Usually when you get toner sticking to the drum, it's called "striction", it's because the clearcoat on the drum surface is worn through. There are ways to clean off the contamination, but once that clearcoat is worn through it will return quickly in the same places.

For a very temporary improvement clean the drum with a cotton pad and a very small amount of Contractor's De-Sol-Vit, or paraffin lamp oil. Do not scrub. When it's clean rinse with alcohol to remove the oily residue. Remove the drum from the cleaning unit when you're doing this. Orange cleaner and/or lamp oil will damage the drum blade, and it won't clean the drum any more. Having said that, it is only temporary. You still need to change the drum, it's worn out.

Thanks, good to now. BTW, looking at your signature I kind of have another question, Toshiba doesn't publish service manuals, right? I would love to have Toshiba 5005AC service manual...

Although I have done it in the past, I personally try to avoid anything that might leave an oily residue on the drum surface. I've had surprisingly good results with some acetone and a really soft cloth, if you are gentle enough it doesn't scratch the surface if you buff it lightly. I've also found my fingernail soft enough to not scratch the surface although it's usually a last resort.

You younglings missed out on the old days of polishing selenium drums with brasso .... Drums of today are too soft, I also have never had much luck in polishing out scratches.

[blackcat4866]

Lol. Not as young as you think. Yes, I've polished Mita drums, with limited success.

[Rusty.Harris]

LOL, I'm so old, I've polished selenium drums with Brasso

[djbass]

So we've all done it then?

[Larhal]

Yep ! Lots Xerox drums, Brasso, cotton balls, elbow grease.

I use WD40 to clean the drum and then glass cleaner to remove the WD40 then dry it very well. Works great.

how about those bright orange Gadolinium Arsnic ones...all the warning labels it came with... O_O

It can't be as poisonous as they say. I'm not dead yet, lol.
