When printing the sheet comes out half black

Sounds like the Photo-conductor is going bad. If it's a separate part in your printer, you just might want to change it out. Otherwise it might also be built into the toner cart, and you'll need to get a replacement toner cart. Not usual but, i've seen a few bad toner carts.

Hope this points you in the right direction.

Price of cheaper priced ipads

Could you be more specific. Taking a wild guess if you are looking at for a cheaper priced iPad then Apples own refurbished site is a great place to start. Ebay is another place if you want to sample the used market. As a precaution make sure you get a model with enough storage, 16gb IMO is too small, a few books, a game or three and some songs and now you're stuck with not enuff storage and no means to upgrade without buying another model.

Changing fuse on Bretford Mobility Cart 20

First thing to check is if the power cable has been pulled out of the power supply under the top surface of the cart. Ours was pulled up just enough to not power the cart, even though it looked like it was plugged in. If that isn't the problem. then you will find two wing nut screws holding the power supply unit in place. Unplug all three cables running to the power supply, then unscrew the wingnut screws. Lift the black rubber cover off the surface and you can then lift the power supply out. You will find a fuse location you can access with a flathead screwdriver.

Bretford iPad Cart Static Electricity problem

This was straight from a Bretford tech:

There are no capacitors or anything that can hold a charge on the cart itself. The only thing that we've been able to come up with thus far is that dry air in the schools may help generating static electricity. Common precautions would be 1. make sure the ground plug is still on the cord. (This can get broken off if the cart is moved with the cord still plugged into the wall.) Plugging the ground cord in won't help however if the person has to grab the door handle to open the door to get to the wall outlet. 2. If the air is dry (ie: people get shocks even without the cart or the problem goes away in the spring when the humidity goes up), gently push the metal of the cart handle against the door frame prior to reaching for the door handle. This will discharge any static electricity that was built up as the person walked with the cart safely to the door jamb prior to the person reaching for the door handle.

Drawer 2 doesn't sink

Don't really know the hardware, all I can suggest is since you have managed to sync one ipad have you tried one ipod. The standard response for something that has many potential factors causing a problem is to try syncing each one of the ipods separately, you could find that one of the ipods is causing the whole lot to fail. It will take some time to do but if it is just the one ipod causing it you can remove it and then try syncing the rest. Hope this makes sense?

The other thing is are all the ipods running the same version of the iOS, I saw from the user guide of the Cart that you need to deselect the check for new software updates automatically, could it be that one of the ipods is running iOS 3 and the rest are running iOS 5. You can check this under settings then general and then about and then version.

Hope this helps.

I have a Inspiron 531S that won't power up and after taking the cover off I can't get the bracket off to get to the hardware

1) Computer unplugged from power.

2) Observe Anti-Static Precautions

Anti-Static Precautions:

Your body carries Static electricity. Static WILL fry out (Short Circuit) the hardware components inside a computer.

Computer on a table, computer unplugged from power, computer case open.
TOUCH the metal frame of the open computer case to relieve your body of Static, Before reaching into the computer.

Should you leave your computer in the middle of working on it, upon your return be SURE to Touch the metal frame again.

At the back of the computer case, perpendicular to the Support Bracket, is a Card Retention Bracket.
The small metal plate that holds add-in cards in.
(Ethernet Card, Modem Card, Graphics Card, etc)

Lift the card release lever up to release the Card Retention Bracket.
Swing the bracket up.

Now swing the end of the Support Bracket up that is on the Card Retention Bracket side.

The other end of the Support Bracket is on two pins. With the Card Retention Bracket in an upright position it will lift off of those two pins.

(The end of the Card Retention Bracket that is on those two pins, has half moon shapes that go over the pins. It may be that you have to bring the bracket more down towards the computer, in order to remove it from the computer)

Supporting data:



Now on to the real problem.

Are you going to bypass the Power On switch to see if the problem is the switch, or the Power Supply?

This has nothing to do with the Power On switch, or it's wires.

A jumper wire is used in the 24-pin ATX main power cable's connector.
It is used to jump from the Green (Soft Power On) wire to ANY Black wire. (ANY Black wire is a Ground wire)

The 24-pin ATX main power cable remains plugged into the motherboard. The computer (Power Supply) is plugged into power.

The jumper wire goes down into the Back of the 24-pin ATX main power cable's connector.

P1 in the illustration denotes the 24-pin ATX main power cable, coming from the Power Supply.

This is a more in-depth look at a typical 24-pin ATX main power cable, it's respective connector, and the matching connector on the motherboard,

The view to the far Right shows the 24-pin ATX main power cable plugged into the motherboard, and shows the Green wire.
(Green wire = Soft Power On wire. Also abbreviated as PS_ON)

ANY Black wire you see is a Ground wire.

The jumper wire is a paper clip straightened out, then bent into a U-shape.
Black electrical tape is wrapped a few times around the middle of the U, for your fingers to hang onto.

One 'leg' of the jumper wire is inserted down into the socket hole with the Green wire, RIGHT NEXT to the wire.
The other leg is inserted down into ANY socket hole that has a Black wire.

The jumper wire Must go down into the socket hole far enough to touch a metal connector.
At the end of every wire going into the ATX main power cable's connector, is a Molex female crimped terminal connector,

(The depth is approximately half the length of a fingernail)

The contact period is around 2 seconds.
There may be a spark.
The voltage is 5 Volts DC
Two C, or D cell flashlight batteries produce 3 Volts DC.

IF, the Power Supply comes on, you have a bad Power On switch.
IF, the Power Supply does Not come on you have a bad Power Supply.

This is an example of a Power Supply for a Dell Inspiron 531s desktop computer,

Gray continuous streaks on lower half of copy using Canon IR 1600

I assume you had the issue before you changed the toner, If so the problem is either the fuser or the Laser.
Do this:
start a print job and after you hear the paper feed into the machine open the top cover to stop the machine. You want to stop the page before it gets to the fuser. May take a couple tries.
remove the toner cart.
the page should be under the cart with the image on it.
If the line is on the page the problem is image development(toner or laser).
If no lines the problem is likely the fusing assm.
