Coffee on drums - how to clean this?
 

Hi,

I got a big HP printer (with the optional duplex printing hardware
already installed) for free - the previous owner managed to pour
lots of coffee over and into it and decide to better go and get
a new one. The printer itself still works and just needs a simple cleaning.

But the drums of the cartridge are coffee-stained, too. So I'd like
to know is there a way to clean the drums in a way that would make
the stained parts pick up toner again?

Thanks,
Carsten

The best cleaner is isopropyl alcohol.
There are some issues however - firstly ensure you minimise the amount of light
that gets to the drums (they are photosensitive), secondly depending on the
cartridge type there may be contamination on other parts of the drum cartridge
which may be hard to get at. Lastly, when the cleaning is done the drum may
bind in the cartridge because there is no lubricant on the drum, this is a
powder lubricant that is applied during manufacture, you may be able to get
away by lubricating with a light covering of toner - so only clean as much of
the drum as absolutely necessary.
Good luck
Tony

Thank you for your answer. Actually, I really I will have to disassemble
the part which hold the drums. I think I will do
this on a day Am I relaxed and don't have much else to do.

By the way the alcohol you need is 90% isopropyl, you don't need much but will
almost certainly need to get it from a pharmacy, the lower strength stuff will
leave a deposit on the drum which will do it no good.
Use a lint free cloth and apply it gently.
