need a replacement belt for scanner

lexmark x83 scanner("color copier" and injet printer also in same box).

Belt says
pioneer rubber belt 397 MXL

Lexmark says "it is cheaper to replace [their equipment] than to repair
it" so they don't stock parts any more.

[what ever happened to the federal law that REQUIRED manufacturers of
consumer electronics equipment to maintain a parts supplies for 7 years
after last sale of the model??? And to make available service manuals??? If
the laws have been repealed, perhaps we need to have them unrepealed. If
they are just not enforced, perhaps we need to push for enforcement!]

Google has not given me anything that looks like the 'toothed, narrow
belt' that may be 397 mm long (the scanner scans legal sized documents) by
2 mm wide. (I don't have it at hand so am just guessing as to the size).

Anyone know where I can get a new belt? Mine seems to be stretched (the
spring tensioner/idler pully has reached end to travel) and to be slipping,
making loud popping noise.

Since you can't buy it from Lexmark, you google around (lexmark
replacemnt part) and find that independent parts houses are taking up the
slack. For example:

I had tried google but got no hits that were useful. Perhaps too specific
or not specific enough.

Not sure if sparepartswarehouse can help either, but have submitted an
enquiry to them. The part that shows at the above link may or may not be
what I need but since it seems to be a laser printer belt, I have some
doubts, but we will see what they say.

Thanks for the help.

I believe these are called cogbelts.

 

Thanks!

That may help.

If you can't find exact belt you might try browsing www.smallparts.com .
They even have belting of different diameters that you can heat the ends
and fuse together. RM~

 

I remember doing that in the early 70's when I had a consumer electronics
repair shop in Texas. Sometimes we had to 'make our own' turntable belts.

I guess I might even take this one off, 'remove the slack' by cutting out a
section or two and get some more life out of it by using a bit of super-glue.

Of course, that may not work if it has stretched too much.

Well, you need to be concerned about size _and_ pitch.

I'd say futzing with ("re-engineering") the tensioner to snug it up
might be a Best Approach. Firstly, tho', check for non-binding movement
over the full scan path. Unhook the belt (that should be all that holds
the scan assy in place) and see that it slides freely. You did mention
a "thunk" and slipping belt in an earlier post.

Jonesy

 

I found another scanner of a different type that used a spring that rides
on the belt and provides tension. I am going to try to use it to 'take up
the slack'.

It seems to be working. May take some adjustment (making sure it is in
exactly the right spot) to make sure it doesn't bind anywhere during
normal travel. I only have had time to try one scan and it seemed to get
rid of the slipping (with loud popping noises as the normal tensioner
[lack of proper tension because it was at end of travel] let a tooth ride
up and over the driver 'pully gear'.

Going to still look for a replacement belt because I expect the belt will
continue to deteriorate.

Yeah, but it wasn't due to binding, due to lack of tension.

None of the ones they showed when I searched for 'belt' were anywhere near
close.

How about just adding an idler to take the excess slack out of the belt?

Isaac

 

Or chop out a piece and add a spring?

 

Not easy to do.

weakens the belt or creates a stiff spot in it.

The current idler is physically limited in its travel, adding a spring
there would not help unless I put a longer rod AND cut a hole in the case
for the belt and idler to travel through!!!


_ ____
Trying a kind of spring that makes a \ /
\ /
O

The belt is pinched together toward the top of the picture,
and pushed to the side, Downward in the drawing, toward the 'O', which
represents one turn of spring stock. The the top ends of the 'V' clip
around the belt and the belt passes below the 'O'. The spring tries to
bring the tops of the 'V' together.



Eventually the belt will stretch to the point where cogs will override
teeth and it will 'jump' a tooth when ever it likes.

The image will show bands of compression or expansion.

Eventually the belt will break.

The belt really does need to be replaced when it has stretched past a
certain point.

Yep, it's a pain. Keep a look out on http://freecycle.org/ or
http://www.craigslist.org/ -- maybe someone has a busted one with a good
belt.

Maybe the Aussies make them stock parts?

I rang up Parts Overnight. Initially they wanted to charge me $30 for
the belt, until I directed them to the price list they had posted on
their own web site. They then told me there was a minimum $20 order,
and that the part was not in stock. Maybe the part is actually
obsolete - I don't think they'll know until such time as someone tries
to order it.
