I got a similar problem with my Umax 4000U some years ago. The scanner failed to initialise after power up. The led was blinking. The supplier told me he only 'greased' the shaft to solve the problem. I got the same problem again after a year. To me it looked like the transport motor doesn't have enough power. Opening the case and pushing the 'scan wagon' from its power off position helped sometimes. Hope this helps a little.

1986 460ci sat 6 months, now seems to be locked up.

If you can't turn the crankshaft with a socket and breaker bar (or large ratchet wrench- 1/2 inch drive) on the crankshaft pulley bolt, then it probably is froze up- will have to be dismantled to see what is wrong. Don 't depend on the starter to see if it turns over-use a socket on the crank bolt to check if the crankshaft is still free turning.

AOC monitor 2436vh does not fill the screen using the HDMI connector. There is a 1 inch black border around the window. Controls to stretch the display are locked out (not accessible) when using that...

The "Best Solution" fixes a problem that is unrelated to the original poster. anononline19's solution is to fix the entire OSD being locked (displays OSD Locked when the menu button is pressed).

Original poster's problem can be fixed by changing your graphics card's "overscan" settings.

Overscan on ATI cards:

Overscan on nVidia cards is currently not supported.

Sharp al 1000, the scanner is on and goes right and left all time

The simple fix is to clean the reference strip under the glass. There is a white strip under the left edge of the glass that the scanner reflects off of in order to set up the scanner bulb intensity. When this strip gets dirty the the machine just keeps trying. I would remove the cover on the left side glass area with the 4 screws. On the bottom side you will see the white strip. Clean this with glass cleaner. While your in there I would go ahead and remove the large glass. Turn off the main power and pull out the scanner bar and clean 3 mirrors. One is the "slot" in the main scanner bar and then the 2 in the assembly to the left that trails the main scanner bar. Once cleaned put it all back together and this scanner bar "referencing" issue wil go away. If it does not (which is rare) then there is a problem with the scanner/ccd unit and the machine is really not worth repairing at this point.
Good Luck and Thank You for using Fixya.

The light on the scanner is flashing intermittently hence it will not operate

When the light bar flashes or blinks, the built-in diagnostics are reporting the hardware is not functioning as expected; it does not necessarily mean the scanner is defective. Before contacting HP for service, perform the following:
  1. Turn off the computer.
  2. Disconnect the power cord and USB or parallel cable from the back of the scanner.
  3. Unlock the transport lock several times to ensure it is not restricting the movement of the carriage. Make sure it is fully open before proceeding to Step 4.
  4. Wait 60 seconds before connecting USB or parallel cable and the power cord to the scanner.
  5. Turn on the computer and rescan to test.
If the light bar flashing is accompanied by a 2117 error, also try the troubleshooting steps included in document: Bps03134 - Scanner not Responding 2093, Unidentified Program Error.

Schlage deadbolt will not unlock even with the use of a key?

it sounds as though the linkage that pulls the deadbolt back has disengaged... if you undo the screws from the inside of the door and remove the manual knob there will be 2 more screws holding the key lock to the door. A thin flat bar is attached to the key lock that goes through the deadbolt and into the manual knob. This bar turns with the key, sliding the bolt on its track to lock and unlock the door. Once the lock is apart check the key in the lock to see if the bar turns when the key does. then see if there is anything that may be obstructing the deadbolt from sliding. The locks are pretty indestructible so if there is a problem it may have been from the install... perhaps the door is to wide for the lock to engage properly and the lock worked loose in the 6 months that it worked.

Scanner bar seems jammed, printer shows busy, all docs cancelled

Open the printer and pull paper. It might come in pieces then shut down printer to reboot it and that should make the symbol go away and youshould be able to start over. At least when I had a problem thats what fixed it. Hope it helps

Makes grinding noises, refuses to scan; WinXP

take a look on the underside of the scanner. there may be a switch that goes from lock to unlock. try to move it to lock and back into unlock. this lock is usually used to lock the bar from moving during shipping. if this got moved back to lock or bumped while you had it turned over, the scanner will not allow the bar to move.. try this first.

Unlock scanner hardware?

I have the same scanner, which has now died due to electrical problems. This was the most posted issue people had with this model of scanner. The problem had come from the issue that the software was never truely adapted for the model. The Visioneer 5800 scanner had a hardware lock on the bottom. When they put out the (advanced) model 5820, the lock on the bottom was seen as pointless, so it was removed, but the software was NEVER adapted for it, except for the original Win98 version. Any version since, has the flaw of requesting the hardware lock being removed. The only way I have found that actually gets around it is this: You have to remove the screw(s) that hold the scanner body to the base, then either put them away in a forgettable box somewhere, or do as I eventually did... toss them in the round file. Now, are you ready for this?.... When the scanner asks the question about the hardware lock, you have to gently pull out on the front lip of the scanner, and lift the main body from the base. Now GENTLY, so as not to destroy anything inside.... You must pull the advance belt so that the scannung bar moves foreward about an inch. NOW, close it up carefully. Now when you ask for a scan, it should work.... I was quite amazed when I first read this solution, but it worked for me for many years of scanning with this machine, and a very good scanner it was, too! Now, if you don't want to do this over and over, and over again... here is the secret that kept me sane (except for when the power went out, and I had to do it again occasionally.) When you scan, use the Passport software, and pull up the twain to scan.... go about your business as usual, BUT!!!, when you finish scanning, close down the scan preview popup FIRST. Then close down the Passport software. IF YOU DO NOT CLOSE THE SCAN WINDOW FIRST, YOU WILL HAVE TO LIFT THE SCANNER LID AGAIN and over, and over, etc. Now, print this before you start unscrewing anything, as it is rather involved. Good Luck! BScott
