Won't scan or copy

Solution
These errors are usually caused by a failed scan, a bad installation, communication problems or software conflicts. Follow the steps below until the problem is corrected.
Step one: Restart the computer
Close all programs and restart the computer. A required task might have stopped running or the system resources might have decreased due to tasks left running. Restarting the computer will refresh all Windows tasks as well as increase the available system resources.
Step two: Check for the correct entries in the Device Manager
Verify that the unit was installed on a DOT4 virtual port in the Device Manager.

1. Right-click My Computer , and then click Properties .
2. Click the Device Manager tab. (In Windows 2000 and XP, click the Hardware tab , and then click Device Manager .)

• The scanning software works after installing the all-in-one software until the first time the computer is restarted.
• In the Device Manager, opening the Properties of the Imaging Device entry will reveal a status of "code 19" or "code 28".
• A Scanner Cannot be initialized error occurs. While this error may other reasons, a virus will cause this error.

1. Right-click My Computer (click Start first in Windows XP) and then click Properties .
2. Open the Device Manager:
   • Windows 98 and Me: Select the Device Manager tab.
   • Windows 2000 and XP: Select the Hardware tab, and then click Device Manager .
3. Locate the Imaging Device entry and click the plus (+) beside it. It may have an exclamation mark beside it.
4. Right-click the all-in-one entry under Imaging Devices, and then click Properties .
5. A Properties screen will open. Look at the Device status section.
   • If the Device status reads, “This device is working properly”, the computer probably does not have a virus problem. Continue to the next step.
   • If the Device status reads “code 19” or “code 28” error, there is a good chance that there is a virus on the computer. Follow the directions in HP document Resolving the Error Message 'Class Installer Has Denied the Request to Install or Update the Driver' (bpu00740) to remove the virus and resolve the problem.
