LaserJet 6MP rollers too sticky.

I have a LaserJet 6MP which is used very little and has not been used
for quite some time (months).

Now the (three) rubber (?) rollers in the back of the printer are too
sticky. The paper sticks to the rollers, causing it to bend downwards
(instead of keeping it straight or bending it up), causing it to curl up
and causing paper jams.

I have tried to clean the rollers. Spirit [1] seemed to make it worse,
more sticky. A damp (with water) cloth seemed to help a bit, but only
for one or two pages.

Is there any way to make these rollers less sticky?

I think that it is very unlikely that I can get replacement rollers
somewhere (FWIW, I live in The Netherlands, aka "Holland"), not to
mention that replacing them is probably quite difficult, if at all
possible.

Any other suggestions?

[1] I don't know if that is the correct English term. Dutch "spiritus".
It is a kind of cheap cleaning alcohol, just not as pure as normal
alcohol.

Frank,

Isopropyl alcohol has the property of drying out rubber. Not sure what it is
called in your language, but that is the chemical name, sold in all pharmacies
and supermarkets here. Alcohol "spirits" are far more volatile chemically, and
I can understand why they would react with rubber to add stickiness.

To get parts for HP printers, go to http://partsurfer.hp.com. You should
be able to find the part number for the rollers if they are available.

There may be other suppliers in Europe that would be cheaper than
ordering direct from HP. The availability of parts varies with different
HP models. However, once you have the part number, you can do
a Web search and see what is available.

An electronics supply store, or a VCR repair shop might have some
"rubber rejuvenator" cleaning fluid. Unfortunately, I have to say that
such products have never worked for me.

Hello, Frank,

there are replacement sets available on ebay from time to time. They're
usually pretty affordable.

Thanks Ben! I used some "70%" alcohol [1] and that seems to be working
somewhat better than a damp (with water) cloth. This time, I could print
some five pages before the paper started to curl again and it did not
curl as much/bad as before (i.e. I could prevet a paper-jam). Since the
problem started, I am using the rear output tray, so the paper does not
have to make the 'difficult'/'sharp' bend back to the top output tray.

I think I will try this for some time, i.e. clean the rollers with
alcohol before printing, and see how things go.

Also my thanks to Aidan and Christian for their pointers to
http://partsurfer.hp.com etc., "rubber rejuvenator" and ebay.

Ah, yes! Denatured alcohol. Much more volatile than isopropyl... Ben
