I have the same problem! I used the MP780 for over a year, since then the problem occured. In the beginning I just had to use the calibration tool but later I had to clean the surface of the scanner, to avoid dust, but now the dust is on the backside of the glass-surface and so unreachable. So according to what I think, it's more a problem of dust than a mechinacal problem.

Everyone above has cut and pasted from the Ricoh manual, which as any tech will tell you is worthless. There is some other setting that must be set to force the "TIFF/JPG" to toggle - hence why no one has figured it out.

According to HP if the problem is only when you print from your PC or Mac then you need to reinstall the printer driver. If the problem is also when you print just from the printer, i.e. scanning or test page, then the problem is with the printer.

My scanner is only scanning 3/4 of the page


My guess is to line up your document right, usually you will find some arrows on the scanner bed to tell you where the corner of the document goes. It's probably on the other side. Good luck!

Scanner not responsive. You can choose to have the document scanned to your PC but nothing happens and either location.


Hi, we need to check first if this issue is caused by the scanner it self or by the scanner driver. Please try the following to check if your scanner is physically functioning or not:

Basic Copying
1. Open the scanner lid.
2. Place your document face-down on the glass. Move your document about 0.1 inch from the top and side edge so your entire document is scanned.
3. Close the scanner lid.
4. Be sure the COPY button is lit. The default copy settings are displayed on the control panel.
5. Press the Color Copy button (for color copies) or B&W Copy button (for black and white copies). Your document is scanned and then printed.
Note: Depending on the copy settings chosen, your copied image size may not be the exact same size as your original.
If the image was successfully copied please uninstall the scanner driverm download the latest driver in http://support.epson.com and install it. Try scanning.

If the issue still present we will need to ensure the scanner is being recognized correctly. Have you had any other scanners installed on the computer previously? We would suggest checking the DEVICE MANAGER for any conflicts.

Get to the Device Manager by:
1. Right-Clicking on MY COMPUTER
2. Left-click on PROPERTIES.
3. Click on the HARDWARE tab, then DEVICE MANAGER.
In the Device Manager please for the following:
1. Any yellow or red X's, question marks or exclamation marks.
2. Under the Category of Imaging Devices - Check for Epson Product name.
If IMAGING DEVICES is listed, test the scanner from PAINT.

To scan in paint:
1. Click on START > ALL PROGRAMS > ACCESSORIES > PAINT.
2. Click on FROM SCANNER OR CAMERA.
3. Choose COLOR PHOTO.
4. Scan.

It is also possible your Windows Image Acquisition (WIA) service is not started.

To start this process please follow the steps listed bellow.
1. Click on Start, go to Control Panel.
2. In the Control Panel window you will Performance and Maintenance, please left click that option.
3. Next we are looking for Administrative Tools, please left click on that option.
4. We are looking for the Services icon please left on that icon.
5. In the Services window we are going to scroll down to the bottom and look for the Windows Image Acquisition (WIA) Service, Please Right click it with your right mouse button.
6. We want to select the STOP option with your left mouse button.
7. Next we want to Right click on the Windows Image Acquisition (WIA) service again and select the START option with your Left mouse button please.

This has something to do the brightness chosen. In the manual mode, if you choose a dark output, the output will have tis area also; if you choose, lighter output, it will omit. In the auto scan mode, the scanner decides what is the best output.

Unable to use film adaptor


Please do the following to scan slides or negatives in manual mode of the Epson TWAIN:
1) In the program you are working from, begin the scanning process. If working in full auto mode, as the scan begins you will see a message that reads TO CANCEL SCANNING IN FULL AUTO MODE AND SWITCH TO MANUAL MODE, CLICK CANCEL. At this point, click CANCEL, then MANUAL MODE.
2) You will now see all Epson Twain settings displayed. If the scanner has not previewed automatically, click the full page preview button (icon of a paper with one corner folded down).
3) Ensure the settings on the right hand side of the Twain are correct. For example, the DOCUMENT SOURCE for transparencies must be either TPU: COLOR NEGATIVE FILM, TPU: MONOCHROME NEG or TPU: POSITIVE FILM.
FILM here indicates that the item being scanned is transparent to light; this setting is also used for slide scanning. Positive indicates that the image is in true colors (ie the grass is green and sky is blue), whereas negative indicates reversed colors, as produced in some photo finishing processes. (If you are scanning a black and white slide in true colors, choose TPU: POSITIVE FILM as the DOCUMENT SOURCE and BLACK AND WHITE PHOTO as the IMAGE TYPE.)
If the DOCUMENT SOURCE is flatbed, the scanner will not activate the backlight in the transparency unit. If the DOCUMENT SOURCE is greyed out and you cannot select a TPU option, close the twain, reseat the power/communication cable connecting flatbed to TPU, then re-open the twain and try again.
4) Ensure the other twain settings are correct for the type of scan you are doing.
IMAGE TYPE should be color photo for all positive or negative color transparencies, or BLACK AND WHITE PHOTO for monochrome transparencies.
DESTINATION is unimportant, however you should select a RESOLUTION appropriate to what you plan to do with the scans. (There are no hard and fast rules for DPI. As a general guideline, if you are saving scans at original size, a resolution ranging from 400-600 DPI should capture enough information to faithfully record the image. If the slide or negative will be enlarged, you will need to increase this DPI accordingly. We have no guidelines on this; you will need to experiment and view the output to gauge the appropriate input DPI from the scanner.)
PREVIEW. If your scanner is doing an AUTOMATIC THUMBNAIL PREVIEW, the slides will automatically preview and appear in boxes on the left side. Here, you can select or deselect the slides you wish to scan.
If you recieve a message that the scanner could not find the film, click the CONFIGURATION button and uncheck AUTOMATIC THUMBNAIL PREVIEW FOR FILM, then OK, and try the PREVIEW button (page with corner folded down) again.
In this mode, you will have to manually marquee or crop the slides you wish to scan. Use the left mouse button to lasso one slide inside a box made of dotted lines, then click scan. Only the selected area will scan. Repeat this process (manually crop then scan) for as many slides or filmstrips are on the bed.
5) Click CLOSE once scanning is complete. The images will now transfer to the application in use.
