Q: It’s best to do this trick with the hand that you feel most comfortable with. Hold the Zippo with the hinge facing toward your index finger. You want to hold your Zippo between your thumb and forefinger with the lid sitting enough above your hand so that it can open the lid fully without being blocked.
A: Hold your Zippo in your primary hand.

Q: To determine whether you need to adjust your truss rod to lower the action, you must first take a close look at the neck of your guitar to determine whether it is upbowed or backbowed.  An upbowed neck will bend up slightly when you hold the guitar flat in front of you, while a backbowed neck is going to bend downward slightly. To check the straightness of the neck, hold it at eye level and look straight down the neck, or lay it flat on a table or bench and look at the neck at eye level. There's another way to check the straightness of your guitar neck, but you'll need a helper. Press a string down at the first and 14th frets. Have your helper line up a ruler next to the string you're pressing down at the sixth fret. There should be approximately 0.01 of an inch (about 0.25 millimeters) between the string and the fret. The truss rod is a slim, steel rod inside the neck of your guitar. You can find the adjusting nut either at the peghead or through the sound hole, depending on how your guitar is designed.  An adjustable truss rod is either one-way or two-way – also known as single-action or double-action. A one-way rod will only straighten the neck of your guitar against string tension and upbow, while a two-way rod can also correct a backbowed neck. With a one-way truss rod, there's no way to adjust a backbowed neck. However, if you have a newer guitar you typically have a two-way truss rod, since these became standard in the 1980s. Particularly if your truss rod is only accessible through the sound hole, you'll want to loosen your strings before you attempt to adjust your truss rod. This will make it easier for you to get a tool into the sound hole and turn it. However, don't remove your strings entirely.  Check the truss rod to see what kind of tool you're going to need for the job. Typically it will either have a nut or a hex key slot. If your truss rod is only accessible through the sound hole, you'll probably want a longer allen wrench or nut driver to turn it so you're not trying to stick your whole hand in the sound hole. If your truss rod is accessible from the headstock, you don't need to worry about the sound hole. You just need to unscrew the screws holding the truss rod cover in place. When you're adjusting the truss rod from the headstock, don't loosen your strings – you need to have them tuned to pitch so you have appropriate tension on the neck and can see the extent to which you're adjusting it. Use your allen wrench or nut driver to slowly and gradually turn the truss rod screw. You may need to lubricate the truss rod nut, especially if you have an older guitar or the truss rod has never been turned.  Remember "righty-tighty, lefty-loosey." Turn the truss rod screw to the right to straighten an upbow, and to the left to straighten a backbow. Place a mark on the nut so you can tell where it was when you started. Don't turn the screw more than 1/8 of a turn at a time. This will keep you from adjusting too much. After you've made your first 1/8 turn, you'll need to retune your guitar so you can check the distance between the strings and the frets and see whether you've corrected your problem. This isn't something you can just eyeball with loose strings. The neck must have correct tension on it for you to be able to tell whether you've straightened it enough or not. If the first 1/8 turn didn't correct the upbow or backbow in your guitar's neck, give your truss screw another 1/8 turn, then retune your guitar and check again. Keep note of the mark you made. Don't turn the screw more than one complete rotation, as this can cause major damage to your guitar.
A: Check the straightness of the guitar neck. Locate your guitar's truss rod. Adjust your strings. Turn the truss rod screw. Retune your guitar. Repeat as necessary.

Q: If your printer is an "all-in-one" model, it can scan. Some other printer models can scan as well, though you'll need to check the printer's documentation or product page to ensure that this is the case. . Most Canon printers that can scan will also be able to connect wirelessly via a touch-screen panel, but you may need to connect your printer to your computer via USB cable. Press the printer's "On" button. If the printer won't turn on, make sure that it's connected to a working power source. Lift up the scanner's lid so that you can see the glass bottom of the scanner.  If your Canon printer has an all-in-one paper feeder, insert your document into the tray instead. You can look at the symbol on the tray to see how to insert the paper. Consult your Canon's instruction manual if you can't figure out how to use the built-in scanner. You should see markings next to the glass bottom; these usually indicate how the document should be oriented in the scanner. Make sure that it is firmly shut before you scan your document.
A:
Make sure that your Canon printer can scan. Connect your printer to your computer Turn on your printer if necessary. Open the scanner. Place your document face-down in the scanner. Close the scanner lid.
