Reconecting my scanner to my computer

First try to Reset the scanner and computer:
1.
Turn off the scanner power.
2.
Unplug the USB cable and power from
the scanner.
3.
Reboot (restart) the computer.
4.
Plug the USB cable and power cable
back into the scanner.
5.
Turn the scanner back on.

paul here i am, what happened, you suddenly ended our session, do you still have the script? we can continue it there if you want. just watch out for my reply.

the scanner drops out when the power voltage drops too low.
so your 12vdc the ECU is tool low. use volt meter
to find the voltage drop point.
you mean no spark, fire is what fuel does when ignited.
and spark is first. if no spark say, i have no spark to 4 cylinders.
my guess is this.
lost DC power to ECU.
this kills spark
and loss of spark kills injection so, lost power kills injection 2 ways.
find this problem by watching spark and power to ECU.
the ECU will drop out about at 9v.
cranking the voltage usaully sags to about 11v cranking.
now you have a goal 11v min, to ECU at all times.(cept siberia)

If you are scanning documents for editing or saving them as PDF, you will need to install the OCR scan software. The Lexmark OCR scan software is available only on the installation disc that came with your printer. If you lost the disc, please contact Lexmark Technical Support Center to request for one.
If your scanner was working before, it could be just a slight communication problem. 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 scan a document again to verify that the problem is fixed.

Hi Good day!! Follow this method to remove your paper jam:

1. Check to make sure that the power cord is securely plugged into an active wall outlet if your printer is not turning on.

2. Make sure that the USB cable connecting your computer to your printer is securely connected if your printer powers on but will not perform a print job.

3. Remove a paper jam if the "Check Paper" light on the front of the printer is blinking. To do this, first turn off the printer and unplug the power cord from the printer. Open the front cartridge door and locate the jammed paper. Gently pull the jammed paper toward you. Plug the printer back in and turn it back on.

4. Connect your printer to a different USB port on your computer if you are experiencing slow printing. The slowness could be due to a connection problem with your computer's USB port. After you've switched the port, try your print job again.

5. Make sure that a phone line is securely connected from a phone jack to your printer if you are having trouble sending or receiving faxes.

6. Clean the scanner surface if your scans are blurry or have vertical white or black lines. To do this, spray the a soft, lint-free cloth with a mild glass cleaner. Wipe the scanner glass with the cloth and then dry it with another clean lint-free cloth.

7. Hard reset the printer if you are having trouble solving your problem. Turn the printer off and remove the power cord from the wall outlet. Wait at least 15 seconds and plug the cord back in. Power the printer on and try your job again.

8. Restart your computer if you can't solve your printing or scanning job. Sometimes restarting the computer can solve an unseen problem.

Don't forget to vote thanks!!!

Hi there the scanner driver corrupt by sudden power cut. So i suggest you reinstall the scanner driver & after that restart the scanner, computer both. I hope your problem will resolve after these process. Thanks.

I unplugged the power supply several times. So far it seems to be working.

The round socket sounds like the power port, and the square one should be the USB as you thought.

Please respond with the scanner make/model and one of us can verify the connections required.

Verify cables connected properly to the back of the scanner
If the scanner is a parallel port scanner it is likely it has two available connections on the back of the scanner. Verify that the cable coming from the computer is connecting to the IN, Computer IN, computer, or similar connection.
Ensure that the scanner is getting power
If your scanner is not getting power it is recommended that you check the connections ensuring that they are connected properly to the back of the computer and from the scanner to the wall. If you have the scanner connected to a power strip and or surge protector it is temporarily recommended that you connect the scanner directly to the wall.
If the computer scanner is getting power, you should notice the inside light come on when the power is first received by the scanner.
After checking the connections you still get no power to the scanner, it is recommended you contact the manufacturer of the scanner.
Additional parallel port scanner troubleshooting
If you have another device connected in between the scanner and the computer, turn off the computer and temporally disconnect the devices connected to or from the scanner. If, after disconnecting these devices, the scanner works, it is likely that another device may have issues or may be unable to work with other parallel devices.
PC Windows users verify no TSRs are running in the background
Press CTRL + ALT + DEL and end task all currently running software except explorer and systray and attempt to scan again. If this resolves your issue it's a possibility that an application in the background such as a virus utility is preventing your scanner from scanning.
Verify the LPT port mode
PC users ensure that the LPT port mode within the computer BIOS is set to either EPP or bi-directional mode and/or try alternating between these two modes.
Update the drivers
Verify that the latest drivers are installed for the operating system being used on your computer. A listing of computer scanner manufacturers and links to the drivers pages can be found on our scanner drivers page.

Hi, disconect your battery positive cable for few minutes,reconect them back and see if this works ,(it should)if not ,play with the wiper swith back and foward,....good luck.....
