SOURCE: cleaning scanner glass

This solution is for the HP 3310 all-in-one.
How to clean under the glass.
1. Find the small wire that runs from the lid to a jack on the back and disconnect it, un-clip the wire from the holders and let it hang free.
2. Lift the lid and pull it straight up about 3/4 of an inch, you will see two indents in the hinge, push these one at a time to release the lid. Remove it completely.
3. 3 screws are located under the hinge, remove them as well as the two in the front.
4. In the back, gently pull on the silver end pieces to release the top from the unit.
5. You can now turn it over to clean the glass.
6. to reinstall reverse the steps and remember to plug the jack back in.
That's it, easy when you know how. Pay HP service nothing!

How do I remove the stand to put my LT19C300 Samsung on the wall

Look for holes in the back of the TV just above the stand. There are screws in those holes that hold the stand on. Shine a light in one to see what kind of fastener it uses. Some are phillips head screws, some use hex head screws. Locate the tool necessary to remove the screws and take all of them out. Have someone help you hold the stand while you lift the TV off the stand.

I have dry hardened dough stuck in the motor area, i need to open it up and remove the flour which is ratteling

hi. 1. remove the screw near the cable. 2. use something sharp, small and robust to lever out the white screw cover which is underneath and in the middle. it looks like plastic moulding. 3. the screw head has a raised middle in the flat head groove. I put a medium flat head screwdriver in a vice and used a hack saw to remove some metal in the middle. it only took 15 minutes so don't be put off. unscrew. 4. lift off the cover. 5.use a toothbrush and the something pokey to clean.

Head won't lift without force. The head lock is in the Unlock position but it doesn't lift up easily. I have to stand behind the unit and use a lot of force to pull it up. It was fine one minute...

Presuming all looks OK near pivot & lock mechinism? can you see the locking hook in rear of mixer head at the hinge area directly behind lock lever, and is it nested in the slot on the base, or is it jamming up outside the stand and scratching it up?
There is a flat-head height adjust screw to control clearance between spatula and bottom of bowl visible from head-back position- leave it alone. There is a headless set screw visible when mixer is upside down to hold the pivot pin secure. This must be loostened with long-shaft flat screwdriver to remove the pivot pin for head removal if necessary ---avoid removing the pin if possible.

Is the hinge stuck with film of sticky sugar, milk-glue residue, ot the like? That is most common cause, distant second is the lock mechinism alignment (very rare)

Its important to keep head from wobbling side-to-side in use, so dont file or sand anything
Can telephone 609 213 2222 if necessary no charge for my talk.

How do i change a 120 amp fuse

The 120 amp fuse has long prongs with circular holes in them, two small hex bolts go side to side through the casing into the prongs. The only way to see the bolts is to lift up the entire plastic grid that all the other sockets go into. The grid snaps on/off the main housing which lies underneath. There are 4 plastic tabs that need to be pushed inward with a flathead screwdriver in order for the grid to be lifted. it is quite possible another fuse is housed next to one of the bolts, with it's own separate small plastic housing. It likely can be slid down and removed, so you can access the bolt the bolts that hold the 120 amp fuse, are different sizes. The one on the right is slightly larger and can be removed with an 8mm hex socket with a 3" extension on the handle. The left hex bolt slightly smaller and is attached to some small wires (to the alternator) and a smaller 7mm socket is used.

1) the drum heater sensor is dirty. lift top cover & look for the large white plastic part to the left of the stripper guide . The sensor is underneath this - to get to it you have to remove side then top covers to reach the screw holding it in place. Clean & replace. If this doesn't work then.....
2) the heater lamps have blown. Unplug from power, remove front cover, remove side covers, remove maintenance tray, remove/loosen blue plastic tray guides, in the front of the printer two torx screws will remove chrome duplex plate, remove paper entry assy by first removing clutch on left hand side of printer attached to paper entry assy,remove assembly (1 torx on right hand side & 1 split washer left hand side), unplug power connector (right hand side of printer going into paper pre-heater) remove two more torx screws to drop pre-heater assy from front of printer - check the two lamps and replce if neccessary. Reverse to refit the bits

How do I change the spark plugs on my 1999 SAAB 9-3? Do I have to lift the engine or is there an easy way to access the removal and installation of the plugs?

Remove the four screws from the ignition cassette located in the center of the valve cover. The sparkplugs are underneath it.

How do you remove the agitator if something is caught underneath.

On a Maytag the agitator either has a bolt under the center cap, or a set screw along the side about 3/4 of the way down. Maytag Alantis and Performa models have a removable agitator cap with a bolt underneath, while the Dependable Care series have a set screw. In either case, you loosen the nut or screw, and the entire assembly will lift straight up. Sometimes they stick and require a little effort to remove. I hope this helps you.

I Don't Have The Key

Darryl - lift up the top part of the scanner body (the silver part should separate from the black base) and let the kick-stand support the top part. Then look underneath the top part; there'll be a green tab sticking down from the top. If you look closely, you'll see little icons next to it that look like padlocks, one in an unlocked position and one in a locked position. Push the green tab away from you so that it lines up with the unlocked padlock, and that should do the trick.

KitchenAid K5SS Switch lever replacement

Remove the philips screw at the back of the head, and remove the name band. This exposes the 4 screws underneath. Unplug mixer. Remove the 4 screws and lift the top off of the head. Switch and motor are right there. Gently remove the 4 wire plugs, after marking them. Unscrew the 2 screws holding the switch down and lift out the switch.

you will need to remove the jack pack cover on the back of the unit (plastic cover), it should pop off, then remove the screws holding the stand on (should be 5 if memory serves).. after that the stand should slide away from the tv.

make sure your wall bracket kit can support the weight and that the screws you embed in the wall are using hercules hooks, anchor bolts, or something similar... last thing you want is a dead tv and ripped up drywall.

hope this helps,
