    My SCX-5421F shows 'Scanner Locked' and doesn't allow me to copy or scan, printing however works. And, I couldn't even find the so-called 'Lock/Unlock' switch (or button for that matter) on the device. Any help, please?

On the underside of the scanner assembly is a LOCK, it has two positions LOCK and UNLOCK. The manufacturer sets it to lock so the scanner doesn't move during shipment. You should be able to slide this to the unlock position.

I cant seem to find a scan option on my epson

Once all of the drivers are downloaded and the printer is connected to your computer, you can initiate a scan of a document two ways.

First, you can select Copy on the printer and it will copy the document placed on the scanner.

Second, you can scan a document to your computer by going to: Start > All Programs > Accessories > Paint.

When the Paint program opens, (in the upper toolbar) click: 'File' and scroll to 'From Scanner or Camera'. Then, select your device (Epson scanner) and click, 'OK'.

Continue with the prompts and your scan will be imported into the Paint Program. To save your scan, Click, File > Save As > (name your document) and select a folder for your scan to be sent to.

If you found this information helpful, please give me a big thumbs up when you rate my answer. Thanks.

My Visioneer 8650 flatbed scanner with auto document feed gives a message when I try to scan a document, telling me to move the switch on the bottom from the "locked" to "unlocked" position. The lock is...

Actually a very common problem. Try the following:
1. Power down then re-power up the scanner.
2. Try slightly moving scanner. Sometimes a small change works to fix.
3. Change one of your scan setting to flatbed scan (not adf). Do a test scan under this setting. This will usually kick start scanner unit to unlock.
4. Last resort, by does also work...give it a medium slap on the side, sometimes unjams the scanner light.
5. Super last resort, power down over night, it almost always works the next day. (could be that lock up is heat related to scan lamp, dont know but just a guess).
Excellent scanner, so worth the effort to try these fixes.

I want to copy a document

How often do you need to "copy" documents. Do you have a document scanner?  Your Epson is a printer.  You'll need a scanner to scan a document into your PC then you can print it out on your Epson.  If you only need a copy once in a blue moon, and you don't have a scanner, save yourself a few bucks and just go to Kinko's or maybe even your local grocery store or library and run your copies there.  They probably cost about 25 cents a page.  A new scanner will run you about $100 bucks.  If you decide that you need a scanner, you might even want to consider investing in a multi function printer which will scan-print-copy-fax.  Hope this helps.  If so, please remember to rate my solution.  Thanks.

Samsung CLX 3170 scanner locked

Many scanners contain a scanning head lock to keep the scanning head from moving during shipping. This may still be still be in the lock position. All scanners are different but check the documentation on how to remove the head lock.

The L1 is indicating a scanner lock.

1. Turn machine off.
2. Make sure the scanner lock is unlocked. This is a clear plastic knob. (it is located on the left hand side of the machine under the document glass in the copy exit area - check your manual for a picture.)
3. Turn machine back on, watch scanner to see if it moves.
4. Try a copy.
5. If you still get an L1 then it might need service because the scanning bar is jammed.

This also is a fix if you are getting blank copies.
Hope that helps...

Scanner Imaging problem

Your scanner’s lock switch may be locking up the carriage unit. Depending on the model you own, your scanner’s lock switch resides in one of two locations. You can find it beneath the scanner itself or in a corner next to the scanner bed after you lift the lid. The switch should be marked with a locked and unlocked padlock symbol; slide the switch to the unlocked padlock to unlock the carriage unit.
It’s also possible that the supplied USB cable is improperly connected to your computer. Connect the cable directly to your PC. Canon’s online documentation indicates that scanners that connect via a USB hub may not work properly. Once you have unlocked your scanner and properly connected it directly to your computer, try to rescan the image.
