Try uninstalling the scanner driver. Then unplug the scanner. Reinstall the scanner driver on the computer and then plug the scanner back in (USB connection).

Hi! My computer (Macbook pro) doesn't seem to recognize my Nikon Coolscan IV software and I get the following message


You've not said what the message is but I suspect that the software is too old to be used on the macbook if it is running OS X 10.7 (Lion) or if you are running snow leopard, it may be a non-intel version of the software. It may be asking you to instal rosetta which would be on your snow leopard instal disk.

If the Nikon website does not have updated software you could try vuescan which according to this page http://www.hamrick.com/vuescan/nikon_coolscan_iv_ed.html does work with the film scanner and you can download a demo version which you can trial before you buy. Hope this helps.

Lexmark X4550 Scanner not working


A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected)> reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).


If that doesn't help, try the steps below:

  1. Disconnect the USB cable connecting the printer from your computer.
  2. On your computer, go to Control Panel > Printers and Faxes.
  3. Delete the Lexmark print object.
  4. Reboot computer.
  5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
  6. When the printer turns on, reconnect it to the computer.
  7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

I am trying to setup the acer scan 620 p on a dell and it doesn't recognize it


If you have windows 7, you should connect the hardware first and let the windows try to get the drivers from the internet.
If it doesn't work you can also try to download the drivers from here.

I installed a printer on my PC and the scanner does not work. Should i install the scanner aswell?


Do you have the combo printer that comes with scanner and printer in one machine? If you do, then one installation should work the device as the computer will recognize it as one. If that's what you have, and the scanner still doesn't work, return the machine and ask for a new one.
If you have separate scanner and printer machines, then you should have two installation discs as each should have its own. You will need to install the scanner if this is the case.
Hope this helps.

When connect my pen drive ( kingstone 8GB G2) it can connect.....it showed on my task bar........and when i open drive of it in my computer it say "please insert a disk into drive H: "...


the computer may have recognized the device as a card reader instead of a thumb drive, try inserting it into a different usb port. And if that doesn't work ,back up the files on the drive and try reformatting the drive.

My computer will not recognize the pandidgital photolink scanner


Try attaching the scanner directly to the computer. If this works, the problem is obviously in the hub. Many scanners will not work if attached to a bus-powered hub. If you have a self-powered (with a power transformer) hub, double check that the power transformer is working (it should be warm).

I hope this helps.

Nikon Scan doesn't recognize scanner


I have the same problem (on XP, Nikon Scan 3.1.2) ... IF I turn the scanner on before the computer (or turn the scanner on and then reboot) then Nikon Scan recognizes it. Can't say I'm happy with the solution, but it works consistently for me.
