When i move the camera in an up/down motion (gently) there is noticeable feeling of something loose or knocking slightly. I presume its the extending lens and wondered if this is typical for this camera?

Re: Move the camera in an up/down motion
What you call a "knocking" is the lens element used by the optical stabilizer. This element is in the middle of the lens and it's suspended in magnetically when the camera is powered. The lens element itself shifts up/down and left to right, shifting the image projected on the CCD.
This "knocking" or "rattle" is normal.

Knock noise must be coming from something else, such as bad shock/strut, ball joint, etc. Put car up on stands and have helper turn steering while looking for loose part. Find nothing? Put jack or long bar under wheel and move wheel up and down to locate what is loose.
When you turn on the copier the scanner should move out of home position and the light come on. If the scanner moves you have a bad sensor. If the scanner does not move something is binding it up or the motor is bad. Power off the copier, take off the glass and try move it gently by hand, look to see what is binding it up.
Oil the rails, check the set screw is tight on the shaft on the right side.
While you have the glass off check the sensor. Look inside toward the left rear and see if it is damaged or knocked loose.
with the camera upside down. slide the latch to the right, with the same motion slide the door to the front of the camera. I had to gently pry the door to move a little. you might find that there are no batteries currantly in it. thats the way i did mine. good luck your on your own.
SOMETIMES, they can be straightened out with a thin, hard probe, something like a dental tool. They are available at most electronics and radio shops. DON'T use the sharp side, put the curved side against the surface you need to move and GENTLY rub the tool in a lengthwise motion, to iron out the bent area. It might take a while but it does work. It is called burnishing. (Polishing with a piece of polished metal).
Skipping could be caused by various issues including, worn piston oring, cracked lower bumper, weak or missing feed spring, weak or broken spring behind feed piston, or weak/ missing check spring on door. Easy tests. Open door and remove nails, point gun up then down again to check for loose piston. If piston moves up and down, replace oring and examine lower bumper for missing pieces. Piston should stay at the top of cylinder. Make sure that there is spring tension on feeder and on check feeder on the door. Dry fire the gun rapidly against rubber pad or coiled rubber hose. With door open notice that feeder is moving back and fourth just as rapidly as the driver/piston is moving. If it appears to move slower than piston moves or in slow motion, replace feedpiston spring and oring. If feeder moves just as rapid as driver, remove air hose and push feeder back by hand. It should take a great deal of pressure to move feeder all the way back. If spring feels very strong replace oring to feed piston and make sure that the air pathway to feed piston is clear. Good luck
It is possible that the cover must have pushed down or changed the fitting position and moved off to touch when in motion. All what you need is to use a good lader to access the fan-- put the power off and use a tester to see for any leak in voltage to the fan before you touch- now move the blades and listen to the rubbing,if so check the cover and tighten it up. If ther is any bearing noise from the fan use a goos spray from the outside along the shaft( WD40) to wash off any dirt and apply some good lubrication oil, allow it to run and reapply. I hope you try this out. Good day
In the middle of the stop motion screw wheel there is a screw, undo the screw and unscrew the stop motion wheel all the way off, you will now see a three pronged washer, take it off and put it in a different position, put the stop motion wheel back on and just tighten finger tight, tighten the small screw all the way, now loosen the stop motion wheel and press on the foot control gently, the balance wheel should move with moving the machine, if the machine turns then start over again, you can put the three pronged washer upside down if you wish.
it recognises that there is a document it tries to feed it but doesn't go down. Which means that there is something preventing it form coming down.
when the doc i s sensed and the pick up tires start to turn there is a solonoid that turns on ( listen for a noise, or look at the pick up system and see if there is something moving and the tires are not being engaged.( probably knocked out of place)
Does your on/off button appear to be stuck? Might there be any dirt under it? if you gently shake the camera, does the button appear "loose", and is it "unresponsive" when you press it? (i.e. doesn't move) It might be that the "behind the scene" parts are stuck in the down-position, but not the part of the button you see.
if button appears stuck, you might try to give the cam a gentle knock with a scredriver shaft, but be careful! You just want the button knocked loose.
