Computer won't detect printer


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.

You may also try to update your printer driver by visiting the Lexmark website at http://bit.ly/nJ7AgN. Select your operating system, download and execute the file.

    My computer is unable to detect this printer when I connect it. What could be the problem? The printer also does not turn off when I press the power button sometimes.


    If the printer is not being detected correctly check both ends of the USB cable to ensure they are firmly attached. Do not have the cable connected to a USB hub or other device. If possible, try using an alternate USB cable that has been tested with another device and is known to work correctly. Ensure the USB cable is connected to a port on the BACK of the computer if possible as some ports on the front of the computer do not neccessarily supply the amount of power that is needed for printers.

    Check the Device Manager listing to ensure the printer is showing up. To do this power the printer on and right click the My Computer icon on your computer then left click Properties. Select the Hardware tab and click the Device Manager button. Are there any listings displayed with a question mark or exclamation mark? Is USB Printing Support listed under the Universal Serial Bus Controllers section? You may need to click the plus sign beside this listing to expand the category tree.

    If the printer is listed with an exclamation mark or question mark, right click the printer and click Remove, then select Action from the top of the window and select Scan For Hardware Changes. This should 'find' the printer again and the drivers should be reloaded successfully.

    If the printer is listed correctly, try selecting the printer properties (browse to the printer window, right click the printer and select Printing Preferences) and clickc the Ports tab. Ensure the port that is selected is USBPRN01.

    I hope this helps!

    My hp deskjet D2500 was given to me in a warranty exchange 3 days ago. I have bought a usb cable for it and everything hooks up well, although when i go to use it a box pops up on the computer saying...


    Check and make sure your printer is defined in the printer setup, and is selected as the default printer.

    Alternately you can download the printer drivers at
    http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=3571291&lc=en&cc=us&dlc=en&lang=en&cc=us

    and re-install the printer. From the computer being off, make sure the printer is on, and USB cable attached, then turn the computer on. The OS should detect the printer on boot, and automatically install the drivers, or you can install them manually from the downloaded drivers referred to above.
