When I plug in the printer, the scanner light-bar does it's little self-test thing, and it goes to the right a few inches, then back to its home. But the belt gears keep spinning, creating a grinding noise while the gears slip on the belt. This goes on for way too long, then the printer returns an error. It seems that it doesn't recognize when the scanner has returned to it's home position. Is this something that can be fixed with a new part, or is the circuit board shot?
I have the same issue: scanner does not know when the light-bar has reached home position so the motor continues to turn the cog which slips under the belt causing a loud rattling until it decides (incorrectly) that something is blocking the "light-bar" from returning home and it stops and says error "scan unable". I've taken it all apart and I can't even figure out how the light bar is supposed to know when it has returned to the beginning (home) position.... anybody?

My X5150 did the same thing even after unlocking. I finally took the top part off (you'll have to remove two small screws on the top back under the scanner cover and then kind of pry the top loose) and found that the belt had came loose from the scanner bar. I had to push it back into the little slot on the end of the bar. Once I did this, it works perfectly with no errors.
I've just got this problem after a powercut, whilst it was not being used but on. If you have only had it a few months send it in warranty. Think I will have to take this apart and see if the scanner cable/ribbon/drive belt is caught on something or been stretched too much and can be replaced at all. Its like at one end its caught and wont move the scanning head being stuck somehow, caught on something (doubtful tho').
If the glass of your scanner is too close to the scanner array it can jam. The cure for this problem is to open the case and put some narrow strips paper under the glass. If under Guarantee take it back. Doubt if you can bypass the self test.
Try first unplugging the power cables for ten minutes, also restart the computer.
Check if this model has a lock button to secure the scan, this is usually indicated with a lockpad, and is a small tab, if there is one is indicated on the manual.
Plug it back and do the following:
This sounds like an hardware fault, since the scanner starts, but just in case , ensure the drivers are working fine by reinstalling software from scanner disk. And eventually test the scanner on a different computer, for example a laptop. Use the scanner CD to do intall scanner drivers before connecting the scanner.
If it still does not work.
Check if the scanner lamp goes on when you send a scan, if not the lamp must be replaced.
The most likely is that the traction belt had slipped out, one of the mechanichs are stuck, or the motor is faulty.
In this case the scanner must be taken apart, the job can be done at any local repair shop.
Have you been using ink cartridges other than store bought? Reason I'm asking is that i used a refill kit, and tried those half price refill places, only to find ink was leaking out when not in use & clogged up the ends where the cartridge moves across. take a flashlight & look at the ends of the track that the cartridges slide across on, you may see a build up of ink, that won't allow the cartridge to travel as far as it needs to go to run properly.
I had a similar problem, the scanner bar was stuck to the far left side. Here's how I fixed it:
1)Unplug the printer, disconnect any cables/phone lines to it.
2)Lift up the entire scanner bed housing(you will see the printer ink cartridges).
3)Locate the access patch (approx 1 cm x 1 cm square) along the left edge of the scanner bed housing(this is the side that closes in, next to the keypad buttons).
4)Using a small knife blade, peel off the patch from the corners and edges(it's sticky. Save it, you can stick it back over the hole when you're done).
5)Stick a pen through the access hole, and push the scanner bar to the right, approximately 2-3 inches.
6)Now, close the scanner housing, plug in the printer, and power it on.
It should reset and re-calibrate the scanner bar. If it doesn't, repeat steps 5) and 6) a couple times, until the printer correctly performs calibration. Then, you can put the sticky patch back over the hole, and you're ready to go. Hope this helps!
Had the same problem as everyone else here - would copy fine but faxing or scanning resulted in the "whizzzzzz" sound (with or without the sheet feeder) and a mandatory reboot.
I followed the suggestion of moving the scanner head to a different part of the drive belt and it works fine now (at least until that part of the belt wears down!). Here was the procedure - it took about 10 minutes.
Remove all T8 screws from the top of the scanner bed - there are two hidden on the left side under the removable flap and two more hidden behind the front control panel cover, which just snaps off.
There is a bundle of wires that prevents the entire top from lifting completely off, so lift it high enough to clear the plastic parts, then rotate it 180 degrees around and set it on something to support it.
Lift the scanner head until it comes off the guide rod and disengages from the drive belt.
Move the scanner head to the other end of the bed and reingage it onto the belt and guide rod - this is a little tricky to get the belt to pop back into the scanner head, but I got it to go by holding the belt firmly on either side of the head and squeezing both together.
Replace top and all screws, pop control panel cover back into place.
