You need to download and install drivers again. The only website distributing drivers for Mirascan is this one , as Acer dose not provide drivers for this device anymore. You will need to subscribe to website to download drivers
Unplug Scanner before installing drivers, plug it back only when finished installing or when required

    The fact is that your scan is out of production and acer never distributed drivers for XP. This model is not on Windows XP compatibility list and is not supposed to work with XP.
    The original drivers provided were designed for 98/ME/NT.They may work on some XP system, evidently they do not work on your XP motherboard.
    Adding a parallel port card would not help, as it is Windows that cannot manage control of the scanner.
    All you can do is trying the drivers above, if they do not work you will need a new scanner.

Need to find a free download to install

Instructions for installing Acer brand parallel port scanners in Windows XP:

For this driver to work in XP you must install the MiraScan software then install the scanner manually.

Step 1. Download MiraScan v3.424 from the web : Mirascan_v3424p.exe

Step 2. Unzip and install the Mira Scan driver that you just downloaded. After installation , system will suggest you to add a scanner

Step 3. Then, add an imaging device

Step 4. Then the Scanner and Camera Installation Wizard comes up. Click Next at the bottom.

Step 5. Then on Scanner and Camera Installation Wizard screen it will ask you which scanner or camera do you want to install? You want to go where it says Manufacturer and then click on EPPSCANNER and where it says Model it should say color flatbedscanner. Make sure it is highlighted, also. Click on Next at the bottom.

Note: For additional screen shots of this procedure and installation procedures, please read the pdf file posted here: scpinwxp-eng.pdf
The Screenshots show to be for Mirascan v3.423 but procedure is same for v3.424

The application failed to initialize properly

I have the same model and problem if installing from original CD on Windows XP (the driver is old and not for XP). The new XP driver will work.

I have the same problem with my Acerscan 620U flatbed scanner which I have used for years, even with XP home SP2 & 3, after I reloaded the Operating system on the same machine, (after a crash) It would not work properly, so I searched for new drivers and softwareafter not finding anything useful here, I went to and found 2 files for the 620U. A zipped file containing the original (Win 95-98) install disks - 2Megs, (pasted from Driverguide);
Model Acerscan 620U Manufacturer Acer info_icon.gif Operating Systems Win95, Win98 Device Type Scanner File Name
Uploader Notes This is the install softwarefor the AcerScan 620U, which is the USB model. I wasn't able to find itanywhere on and when I tried to download the latestversion off of the Acer website it didn't work, crashed my graphicsprograms. This one worked perfect.How it works
This will give you and
Unzip to a folder called disk1.
Unzip to a folder called disk2.
Runthe 'Setup.exe' file in the 'disk1' folder - halfway through it'll askyou where 'disk2' is. browse to wherever you've unzipped disk2 andthat's it!

I also downloaded a 14 meg file "mirascanv403u10.exe" (<a href="">Acer AcerScan 620U Driver</a>) which is supposed to work with W95-98, ME, W2000, XP (with mixed reviews)and Mac-OSX, I haven't tried either of these yet although I will try the Mirascan file first. For many users the difference may be that when setting up an XP machine you have the option to use a FAT32 file system or an NTFS partition, it may be that the software doesn't work with the NTFS partition/filesystem.

If you send me a request to I will send you either or both of the files as an attachment until Jan 10 2009 then I delete them, (or you can get them from Driverguide) I'll also let you know what worked for me.
