The missing INF

[Sludge]

Got a little problem. I'm not sure if it's a soft or hardware problem.
I have a Lexmark X5650 printer, fax and scanner combo.
USB Port.
The printer and fax parts works fine, the scanner doesn't.
The scanner does work when I disconnect it from the PC (Dell XPS 430)
(Tag #CJGDWH1) (VISTA HOME 64BIT) and scan it to a memory card.
In the Device Manager under other devices it indicates something is wrong
with 5600-6600 Series. I assume, this is referring to the scanner. I right click on it
select properties and under Device status it says.
"The drivers for this device are not installed. (Code 20)
The required line was not found in the INF.
To install the driver for this device, click Reinstall Driver."
I did that and it looks for an updated driver on my PC and the internet.
another window opens with this message.
"Windows encountered a problem installing the driver software.
Windows found driver software for your device but encountered an error while attempting to install it. Lexmark 5600-6600 Series.
The required line was not found in the INF."
I talked to several Lexmark tech guys, somewhere it Asia, for the last three days and all they could do was screw something else up.
They uninstalled then installed, cleaned up, removed, took over my PC and nothing.
Then they tell me to call Dell.
I called Dell ( I purchased this PC in Dec 08) and they wanted $125 before they would even talk to me. Maybe someone out there might be able to help me.
Also what does this mean " The required line was not found in the INF."That's a lot to read, I hope it's understandable.
Thanks

That Windows driver finder is simply a joke, and it'll never find anything.
You have to do it yourself.

First, let's make sure, that "other device" is really your printer.

1. Open Device Manager (Control Panel>System>Hardware>Device Manager)
2. The hardware whose drivers are missing will appear as Unknown device, so it's easier to locate the device.
3. Right click on the unknown device and click on Properties.
4. Under the Properties window click on Details tab and select Device Instance Id from the drop down box.
5. You should see a code similar to this

PCI\VEN_8086&DEV_27DC&SUBSYS_30868086
&REV_01\4&1E46F438&0&40F0

6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:

Vendor ID = 8086
Device ID = 27DC

7. Once you have obtained both the IDs, proceed to PCI Database. There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.

8. Then from there you can go directly to the hardware manufactureres website and get the driver.

Thanks fot the reply
under the details drop down menu, there was no Device Instance Id
There was a Hardware Id and a Device instance Path. There no PCI
In Device Manager under Other device it list "5600-6600 series"
Hardware Id:USB\VID_043D&PID_013F&REV_0001&MI_00
USB\VID_043D&PID_013F&MI_00
Device instance Path:USB\VID_043D&PID_013F&MI_00\7&AF7D8&0&0000
I not sure what to do next.

Have you tried re-installing the 64bit driver?

Since the printer/fax works then it has to be the scanner software causing the problem.

[Broni]

Yeah, vendor ID indicates Lexmark.

I re-installed the 64bit driver? no change

What does this statement mean?
"The required line was not found in the INF"
What is the INF?

[Broni]

INF is a driver. If some line is missing, it means, the driver is corrupted.
