Things to check, verify, or test
Make sure that you are using an IEEE-1284-compliant printer cable between the scanner and printer. Make sure that print spooling is turned on, especially when using the HP Scanjet Copy Utility. Print jobs will be spooled up (saved to disk) until the printer is available, requiring more disk space, especially if you scan multiple pages.
To check print spooling:
From the Start menu, point to Settings, and select Printers.
Right-click the icon for your printer and choose Properties from the menu.
Choose the Details tab.
Select Spool print documents so program finishes printing faster.
If you install a new printer or printer driver, or if you change the way the scanner is connected, you will need to re-install the HP Scanning Software.
If you have problems scanning or printing while the scanner and your printer are both connected to your computer parallel port, run the HP Parallel Port test (from the Start menu, point to Programs, select HP Scanning Software, then select HP Parallel Port Test).
Depending on your printer speed, this test can take a few minutes to run. The HP Parallel Port Test prints a test page and verifies communication between your printer, scanner and computer. The program may be able to change the printer configuration to improve compatibility.
If scanning is too slow or the scanner not responding, contact your computer manufacturer to check your parallel port setting in basic input/output system (BIOS). It should be set to EPP (Enhanced Parallel) for best performance.
Fixes and workarounds
If you still have problems scanning or printing, you can try each of the following (in the recommended order) until your scanner and printer work together.
Obtain and install the latest port sharing (for example, IEEE 1284.3 compliant) printer driver from your printer manufacturer, then re-install the HP Scanning Software.
Turn off bidirectional communication between your printer and your computer. Contact your printer manufacturer for instructions on how to do this.
Do not print and scan at the same time.
Do not use the HP Scanjet Copy Utility. (You may not be able to use the Scan To: Printer destination either.)
Disable the scanner button on the scanner. To disable the scanner button:
From the Start menu, point to Programs, select HP Scanning Software then select HP Scanjet Button Manager.
The HP Scanjet Button Manager dialog box appears.
Clear the box labeled Enable the Scan Button.
Choose OK.
Contact your computer manufacturer about upgrading your personal computer (PC) to support an additional parallel port. You can use a second parallel port to connect the scanner. These changes may involve opening your PC to install an interface card, upgrading your operating system, and/or installing additional drivers. You will need to re-install the HP Scanning Software after you change how the scanner is connected.
Purchase and install a new HP printer. Then re-install the HP Scanning Software.
Installation problems
Issue
Cause
Solution
When you restart your computer, you see operating system prompts about an unknown device in a New Hardware Found dialog box.
You connected the scanner to your computer Before you installed the software.
Choose Cancel in the New Hardware Found dialog box and then install the HP Scanning Software. The Setup program will update your system appropriately.
The printer is not working.
Your printer drivers and/or status monitors for your printer do not allow port sharing.
Use a workaround solution to use both the non-compliant printer and scanner.
You cannot run the scanning software.
The software installation is incomplete.
Restart the computer and try running the Setup program again.
The scanner is not working.
The scanner was not installed properly.
1. Make sure the power cord is connected to the scanner and plugged into an electrical outlet.
2. Make sure the scanner is unlocked.
3. Make sure the parallel cable is securely attached.
4. Completely power off your computer system, wait 30 seconds, and then power on the scanner.
5. Turn on your computer.
Not enough disk space is available during installation.
The Setup program determined that your hard disk space is insufficient.
Either:
1. Create enough space by deleting unnecessary files from your hard disk or archiving older files to disk or other storage device.
2. Install to a different drive.
Memory problems
Issue
Cause
Solution
The HP scanning software is out of available memory.
The system memory or system resources are not sufficient for the application to run.
1. If any other applications are running, close them.
2. From the Start menu, point to Programs and select Windows Explorer. Delete all files in the directory: /WINDOWS/START MENU/PROGRAMS/STARTUP, then restart Windows and try again. (Note that some applications do not release all the memory or resources they take up even when you exit from them, so restarting Windows with no applications in your Start-up group can give you maximum memory and resources.)
3. From the Start menu, point to Programs, and select Control Panel. Then double-click the System icon. Choose the Performance tab. Choose the Virtual Memory button. You should use the size suggested in the dialog box; however, make sure you have at least 16 MB or more of available space on the selected drive. Clear the box labeled Disable virtual memory (not recommended).

Problems scanning from applications
Issue
Cause
Solution
When using Acquire in the file menu of a word processor, instead of the HP Precisionscan software, some other program appears.
The data source for your Acquire command is not set to go to the HP Precisionscan software.
Choose Select Source in the File menu of the word processor, then specify HP Precisionscan software as the source.
Cannot find Acquire in the File menu on the word processor.
Your word processing program may not use this type of access to the scanning software.
Use another method of inserting a scanned picture into a word processing document, such as the Insert Object or Insert Picture commands.
Cannot find the Insert Object command on the word processor menus.
Your word processing program may not use this type of access to the scanning software.
Use another method of inserting a scanned picture into a word processing document, such as the Import Picture command or the Copy and Paste commands.
Your word processor documentation for information on whether an Object Linking and Embedding (OLE) link is available.
The picture is too large or small after it is inserted into a word processor document.
Picture was not scanned at the correct size. Zooming does not change the size of the scanned picture. Set the Region Size in the HP Precisionscan software.
