Not scanning all in one will not scan to screen, copies fine, prints fine, scanner not scanning.

Make sure there is a scanner driver loaded in your computer. The printer driver only will not work the scanner

How are the copies?

Hi

Scanning takes an image on a document on the scanner's platten and converts it to a digital file format stored on your computer.

Copying is scanning + printing.

To copy, you do not need to separately scan first and then print. Just select how many copies you need on the number pad, then press either the Black or the Colour COPY buttons on the scanner (or open the printer's/scanner's software and click on COPY), while it's connected to the computer and the document will automatically be scanned and printed (copied).

I hope this helps.

Form your issue that you are able to print and copy but unable to scan it is very clear that it is a software issue. Copy and scan fuctions work this way.

Copy - completely related to hardware.
Scan - related to software

uninstall and reinstall the full version software from Hp for the operation system of your computer.

PSC 1401 will print but it will not scan

The Scanner has died. If you Know someone else who has the same model but is not printing but scanning fine you can swop over the scanners. This solution don't work 100% of the time but i have fixed a few this way.

You can try the freeware at the link below:

http://www.bestsoftware4download.com/software/t-free-freekapture-download-npbskbaz.html

The description states: "You can also use FreeKapture as an 'ad hoc' copy machine (by using your printer drivers 'how many copies to print' option)."

It works with all twain compliant scanners. Download and install and then point it to your scanner.

Good luck, and please let me know how it works out for you.

Since you cleand the scanner and scans are fine, the other item I seen cause that problem is the power supply.

Are you scanning both black and white and color the same way? The ADF (automatic document feeder) uses a different scanning area than when you place the document on the scanning glass. If you open the scanner cover, look to the left of the main scanner glass to the narrow strip used for the ADF. Make sure this narrow strip is clean -- no ink or white-out or scratches. This can make your copies look dirty or smudged.

sure..new drivers might make this happier..
