of the scanner. Then, gently press and release the reset

working memory or the V-Scanner folders.

If this doesn't work here's step two! CAUTION. THIS WILL ERASE EVERYTHING, but it MAY Fix the Problem!!

2. Press 0. The following messages appear on the display:

5. Do not turn off your scanner until the initialization is
complete. When the initialization is complete, M000 and

Hope this works.. Happy Scanning

You have to have the plastic slide holder (positioner) placed perfectly. Look at the "A" and "C" tabs on the plastic holder. If they don't position your slides over the center of the glass, you are using the wrong tab! Slides have to be back-lit, which is what the top cover does. It doesn't light up the sides of the scanner glass, only the middle.

Open the lid on the HP scanner to reveal the scanning surface. Tthe scanning surface is the glass surface on which documents are placed for scanning.

Step 2 Put the picture face down on the scanning surface, using the positioning mark to set the picture. The positioning mark is normally an arrow and it indicates the correct placement of a document on the scanning surface for a good scan.

Step 3 Close the lid on the HP scanner.

Step 4 Press the "Scan To" button on the HP scanner and choose a format for the scan. "Scan to File" or "Scan to Email" are a couple of the choices. Press "OK" and your scan will begin. On your computer screen, a progress bar will let you know how your scan is going. Once the scan is complete, the folder where the file was scanned will appear on screen and you can click on it to ensure the quality of the scan.

Have you considered simply scanning from within Adobe Acrobat or similar software that produces .pdf and then use the email feature within Acrobat?

As I look over the HP User Manual, I can't see any method to set the default output. It simply says...

Use the E-MAIL button() to scan documents or pictures and insert them in an e-mail message as an attachment. You must have an Internet connection and a supported e-mail application.
1. Place the original face down on the scanner glass or face up in the ADF. If you are scanning two-sided originals from an ADF, slide the DUPLEX switch to two-sided mode.
2.Press the E-MAIL button().A message appears asking if the original is a document or a picture.
3.Select Document or Picture, and click OK.Note:A preview image will not appear when scanning from the ADF. To change this preview setting, see the HP Photo & Imaging software Help.
4. Select the final scan area (the area inside the dotted lines) in the preview image.
5. Make adjustments to the preview image if needed.
6. Click Accept.The final scan area is scanned and your e-mail application is opened. The scanned image is added as an attachment to the e-mail message.
7. The Save As dialog box appears. Type a file name and choose a file type, and click OK.
8. Complete the e-mail as usual.

Press the On button to turn off the Stylus Photo RX500. Unlock the transportation lock. Make sure that all packaging materials have been removed. Turn on your Stylus Photo RX500 again. If the error message still appears, call Epson so they can replace your printer.
Goodluck.

Hi, it is possible that your scanner has a transport locking lever or knob underneath which might have been keeping the carriage locked in place. Try checking and release if there is one. Hope this works for you. Pls post again how things turn up. Good luck and kind regards.
