Making rubber printer rollers more grippy?

[Pamela]

My printer is getting old and sometimes doesn't manage to pull a sheet of
paper from the drawer.

In the printer, two "rubber" rollers on a rotating bar often fail to grip
the top sheet.

Where can I get some liquid coating to apply to these rollers to make them
more sticky?

[Pamela]

POSTSCRIPT

The rollers have been thoroughly cleaned with a microfibre and isporopyl
alcohol. In fact, I wonder if repeatedly using alcohol has hardened the
rubber compound and made it more slippery.

[Andy Burns]

Not sure if this is still the same product it used to be 30+ years ago,
or if it's been re-formulated to be "green and useless"?

That may do a good job of cleaning the rollers but mine have been cleaned
many times. "Leaves no residue" suggests the product contains alcohol or
some volatile solvent.

I would like to make the current rollers more grippy. There used to be a
paint-on solution to make belt drives on record turntables (like the old
Thorens) more grippy and maybe there is something similar for printer
rollers.

Maybe 30 yrs ago I received in the post out of the blue a thing from HP
to attach to my HP printer to rectify a manufacturing fault. It seemed
to be holding a nylon abrasive pad against the roller for a bit. I don't
recall it ever having a problem or that it made a difference, but a
thought for you - resurface it, gently.

Many years ago one model of a HP printer had this problem. They sent out
a fix which consisted of one of those green scouring pads used for
washing dishes. This was attached to a metal plate which held it in
place against the roller and they included a floppy disk with software
which just turned the rubber roller.

Just rough up the rollers with a similar scouring pad or a bit of fine
grit sand paper.

That was what it used to do, but perhaps the rollers back then were a
bit more spongy to start with, rather than hard shiny rubber

[alan_m]

Snap, I didn't have the problem with my printer in the first place but I
used the fix. The printer failed a long time afterwards but it wasn't
because of the rollers picking up the paper.

[Pamela]

Perhaps it depends on how the rubber roller gains traction.

If traction relies on a gummy smooth surface then roughing it up is going
to impair it.

[Brian Gaff]

I think a lot of it is dust. It gets compressed into the surface in the same
way that talcum powder would. The problem is getting at the rollers to clean
them. You really need to give them a good scrub. They used to sell a kind of
paper that was supposed to be put through the printer with a slightly tacky
surface that if used regularly, removed this, but I never had much success
with that.

Well, the issue often is uneven grip skewing the paper and getting it all
jammed up. Photo copiers used to suffer a lot from this after a so called
clean. I remember in them old days you could just detach the rollers and
soak them in a bowl of some liquid, then give them a good clean and dry
them. However the engineers simply swapped them for new ones to save time.

No don't use sandpaper, or worse still, glasspaper, the bits fall off in the
innards. Scouring pads, well maybe, but you still need a solvent or at the
least some kind of way to loosen the dust.
Belts are one thing, but printers need to always slip a little to move
paper till both rollers can grip it.

What is the solvent for dust? A solvent for the rollers is like to just
dissolve the surface and allow the existing dust to stick more.

I have an HP Laserjet, and after my attempts to fix a similar problem
by abrading the surface a bit failed, I bought a spare roller off eBay.
It was 'expensive' for what it was, but cheap in the scheme of things,
and fixed the problem.

For some printers you can get new roller kits designed to fix this
problem. They tend to be a better long term solution that simply
cleaning / abrading the existing ones.

If Benzine worked, I'd expect lighter fluid (the stuff for 'petrol'
lighters) to work.

Brake cleaner is benzene mostly.
Lighter fluid isnt far off either

Future generations will wonder in bemused amazement that the early
twenty-first century’s developed world went into hysterical panic over a
globally average temperature increase of a few tenths of a degree, and,
on the basis of gross exaggerations of highly uncertain computer
projections combined into implausible chains of inference, proceeded to
contemplate a rollback of the industrial age.

"rubber regenerator" or "rubber rejuvenator"

grippy sprays don't last long. Better to rely on degreasing & light sanding if you can. Once they're too far gone for that, sand it some more and glue a rubber band on. I assume a thin smear of silicone could also work, not tried it yet.

[Thomas Prufer]

I have used an industrial rubber rejuvenator for offset printer sheets, and that
worked a lot better and lasted a lot longer than brake cleaner & Scotchbrite
did.
