Soles on arch shoes

I would say that any shoe repair shop could help you with this problem. If the rubber is rotten, perhaps it has gotten in contact with gas, oil or some solvents. If it is not rubber, then it may have been kept in a place with too much humidity.

One of the bottom aluminum and rubber feet on which the subwoofer sits has gone missing, where can I get hold of a replacement Thanks

Unless you contact the parent company its close to impossible to get that feet. But you can buy a set of four rubber feet at any hardware store and replace them all.
The feet come off when one tries to push a heavy sub like Velodyne instead of lifting it off the floor and placing them . The rubber grip is so good on the floor and when we push the top part of the Sub the feet rip off.

Paper wont feed in and get bunched up

Hi Dianne
When paper bunches up it generally means there is an obstruction in the way - after the paper has gone into the rollers.
Sometimes it's as simple as a bit of debirs or even a pin off the pinboard has fallen in. However. a couple of instances have been that in the platen (the bit the paper passes over while the ink is being quirted) there is a strip of oddly cut sponge foam - and this foam as somehow come out of its seating and is getting in the way.
Open the printer as if you are going to replace the inks but take the whole print-head out. (take the inks out first then the print head) Then look at the metal plate and you'll see the foam. Is it dirty? is it wrinkled? is it sitting fluch with the surrounding surface?
Carefully remove it with tweezers (or rubber gloves) and give it a good wash in warm water until the water runs fairly clear.
With a damp piece of paper-towel, clean off the metal plate and the recess where the foam came from. When you are happy that it's clean squeeze the foam between some clean paper towel to remove as much water as possible and then carefully fit it back into the recess. - it's a bit fiddly but it will only go in one way round so you can't get it wrong.
Refit the print-head and the inks and see if matters have improved..
If they haven't then you will need to locate your nearest Canon centre.

I have a 13w7 and i am wondering if its possible to find the replacement foam around the top of the speaker. mine has a tear in it and i find it hard to believe that the speaker would be wasted because of...

The foam is molded, you can not remold / repair
If it is a small tear you can repair with a bit of rubber cement. Eventuly it will fail and more will tear causing the sub to sound very bad

My subwoofer is no longer working. the foam inside has gone bad/rotten and I want to know if there is a replacement and how the heck do I take the subwoofer apart to repair it anyway?

this foam gave nothing to do with sub, it was there to cancell echo from casing, if speaker, regardless which, is gone bad, there is no repair for it. it need to be replced.

in your case, if sponge is gone, most probably membrane deteriorate and go off the coil as well, you cannot fix that unfortunately.

if you find my advice helpful, please do not hesitate to give me your vote.

Smells like rotten eggs

The smell of rotten eggs normally means you have some water that has been sitting arround awhile and has gone bad. You may have to unplug your machine and remove the front cover to take a look arround the inside of your machine to see if any water has leaked out and has puddled up. You may also have something caught in the drain pump's filter, which may have gone rotten from sitting around too long. This filter is easy to unscrew and gain access to once you have the front cover off. Make sure you have lots of towels or a wet vac handy when you unscrew the filter cover.
