I am using windows Xp and I have an HP Photsmart C4200 printer that I just connected and it keeps saying usb not connected when I try to scan. Everything is connected because i just printed but the scenner is not working. HELP!

will it work with PAINT?

do you have the correct drivers downloaded for scanning? go to this page <A href="http://h20180.www2.hp.com/apps/Lookup?h_pagetype=s-001&amp;h_lang=en&amp;h_client=s-s-r2515-1&amp;h_cc=us&amp;h_query=HP+Photosmart+C4200+All%2din%2dOne+Printer+series">http://h20180.www2.hp.com/apps/Lookup?h_pagetype=s-001&amp;h_lang=en&amp;h_client=s-s-r2515-1&amp;h_cc=us&amp;h_query=HP+Photosmart+C4200+All%2din%2dOne+Printer+series</A>&nbsp;and find your printer and go throught the diagnostics tool, it wil fix it for you

I would suggest that you uninstall, cold boot, and reinstall. Be sure to follow the instructions closely....

Check these HP FAQS:

• 'An error occurred while communicating with scanning device' Message Displays in Windows XP When the Device is Connected to the Computer with a USB Cable (Windows XP)
• In Windows Vista the message 'An error occurred while communicating with scanning device' Displays When Scanning with a USB Connected Printer (Windows Vista)

If you have Windows Vista, and the FAQ above doesn't solve your problem, you might need to update your driver/software. Read this:
Installing the Product Software in Windows Vista for a USB Cable Connection

hi, here wht u need? http://h10025.www1.hp.com/ewfrf/wc/product?product=3192753&lc=en&cc=us&dlc=en〈=en&cc=us

This is a HP hardware/software error and HP has not fixed it.

The C4250 may report that "USB is not connected" but the printer works just fine and when you use the Microsoft Scanner and Camera Wizard to carry out a scan, it works just fine too. So the error message is wrong.

The Microsost Scanner and Camera Wizard can be found on the Control Panel.

Use the scan commands from the HP device manager, not the printer.

plz check is your usb ports are working if yes then try the printer in another port or pc.You can scan your pc for viruses

a connection without a driver isn't complete go to www.hp.com select the product , search for the drivers and than it will by BOG not only bong but also scan and print

I had the same problem.  The thing is I was pressing the scan button on the printer and getting the lovely "USB not connected" message.  However, if you open the printer icon in the dock (Mine is "HP Photosmart C4200 series") and click the Scanner button in the upper right hand corner, then click "New Scan," voila!  presto! and all is right with the world again.  
Yes, it is obnoxious that HP made a defective scanner button, and I may download the driver again when I get a chance.  But yay for quick fixes!
