CS 255 - What do you think this is stuck to the UFR?

[User Name]

What do you guys think this is that was stuck to the UFR?

This is right after I started cleaning it off. The liquid on it is the WD-40 I was using to clean it.

It turned a milk-chocolate brown color as it dissolved and would flake off with some gentle scratching with my thumb nail.

It cleaned up nicely but I don't know why this substance stuck to it. This fuser unit only has 10k on it and the UFR doesn't look worn out.

I'm going to guess it's toner. ?? Cleaning off toner on the CS-2050 series turns a brown color sometimes. Wierd.

That's what I thought it was too but my boss is positive it's not that because it isn't black.

But my cleaning it with the WD-40 may have started to turn it brown? I didn't take a pic before I started cleaning so it may have been black beforehand. Idk. I hate when my boss questions my judgement.

It is really hard to clean the upper fuser rollers for some reason. Takes me 15 minutes sometimes. I use fedron, alcohol,dispersant. Fedron works the best I think. BUT the black toner on the fuser roller is black and then cleaning with a solvent turns it brown. Like I said , really wierd. Next time let your boss clean it.

It is definitely toner! It happens on other models as well. As BlackCat pointed out in another thread, to improve first copy/print out time the unit produces a page before the fuser is completely up to temperature when coming out of power saver mode. A small amount of toner adheres to the UFR which over time then becomes noticeable and is "brown". We had a number of units that exhibited this problem. Increasing the time before the unit goes into low power or sleep mode seems to have solved it for us. Thank BlackCat for the heads up.

I am going with a transparancy that was hot rated for copiers.

It could be special sauce. If customer had a party at the office the night before.

Check that the customer is not using inkjet paper, the coating can come off in the fuser

This particular customer doesn't make a great deal of copies so it could possible that machine is going to sleep between every copy job. I'll check the settings next time I'm there. Thanks for the tip!

Of course, it could also be that the toner we sell to customers is less than OEM. *sigh*

I've had transparencies get stuck to a fuser before and this didn't remind me of that and I really doubt this particular customer (a Dr's office) would need to make transparencies. Thank you for the opinion though.

Why don't they ever invite me to their parties?

That's not a bad idea to check that the next time I have to go there for this problem. Thanks!

Did you qualify whether it was generic or OEM toner? I had a really bad case of generic toner on the developing roller and fuser of a FalconII.

It looked exactly like what you've got, and it was definitely generic toner. =^..^=

It's not OEM so... yeah. My boss won't be convinced that the toner is the problem until every other machine out there also has the same issue.

I'll take a stab in the dark and guess it's Katun toner....and good rule of thumb when you have a boss who uses non OEM toner....keep documentation of all the parts you replace because of crap toner and show him how much money you are saving....

Bingo

Nope. I'm done bothering. I argued enough with him about how I thought it was a bad idea before the switch. I'm fine with him wasting money if that's what he wants to do.
