Transparency adaptor won't close

Almost overnight my Epson Expression 1680 Transparency adaptor wouldn't close properly, leaving a gap of about 2" open. I used some w-d 40 in the hinges because they seemed stiff. No help. I was able to continue to use it, but now It has gotten so serious that I now get error messages when I try to scan "Close the Transparency Adaptor"
Opening it wide,I looked at the back end where the top is screwed onto the bottom. The right hand side of the metal bracket is actually bent, just to the right of the 2 large screw type sets (there are two pairs of screws). This is because of the times i pressed down trying to make it close.
I am guessing that something internal has come undone, knocking the unit out of alignment.
Any suggestions? Has this ever been described before?

    I have the same problem with the 1600. Actually, it is now stuck in the completely open position! As it seems to be a problem with the hinge unit, I am going to contact Epson to see about getting a new hinge unit.



    Thanks for posting!

Remove the transparency adaptor from the scanner bed (unscrew the two smaller screws, then slide back and off) and then remove the glass (and plastic frame) of the transparency adapter (there are six screws).

By the hinge there is a small white plastic switch. Usually the transparency adaptor hits this when it's closed, letting your computer know that it is ready to scan. What I did, as bcvideo did, was take duct tape and firmly taped the switch to the side of the transparency adaptor, using several small strips of tape.

The scanner works well now. You may need/want to put something on top of the scanner if it does not fully close.

I have the model Epson expression 1600 which is similar. Remove the transparency adaptor from the scanner remove the six screws that hold the bottom glass and plastic half of the unit. I used a bit of silicon based grease on all the surfaces that slide in the hinge mechanism. Note the micro switch on the right side of the hinge. It has to be depressed when the lid closes or the scanner thinks the lid is open. Over time the hinge mechanism gets slightly bent and it wont trip the switch. My solution was to just tape the switch closed. You may come up with a more elegant solution but the switch is the problem. Reassemble and your scanner should work with transparencies without the error message

Had the same problem. By lid I assume you mean transparency unit. To fix, it is necessary to remove the transparency unit from the scanner. Then IN A CLEAN AREA! with the glass side up unscrew the 6?screws that hold the top unit together. There will be a hinge assembly inside. You must remove it, clean it, and re grease it thoroughly. I used lithium grease from an aerosol can. Has not given me problem since. the whole process took about a half hour. just make sure you are gentle, and keep everything clean.

Fuzzy scanned image from Epson Expression 10000XL scanner


Make sure that the item being scanned is lying flat against the scanner's glass. If the scanned image is still fuzzy after adjusting the object, clean the scanner glass with a lint-free cloth and some vinegar or ammonia-free window cleaner.

Lines through negative scans


Clean the glass surface with Iso propyl alcohol (Industrial grade is enough). Dont use any solvent. Just for immediate usage, you can use your aftershave and clean. Clen with a soft cloth.

Scanner won't turn on


Hi,
Try to test the power cord of the scanner (cable from scanner to outlet) using multitester if there is an electricity or if you have extra power cord test it. Maybe that's the defect. If that's not the problem it is now the scanner itself, have it for the repair man or technician.
Thanks

Hi-

Do you have any existing drivers for new epson scanners( models), if you have then there are compatibility issues between new drivers and old drivers, are you using a leopard 10.5 operating system or tiger 10.4.**? try uninstalling every epson info from applications folder and from library/image capture and library/preferences. you an use the finder to search for epson scan and drg them all to trash. Try using image capture application as well if it will scan when you run it, then reinstall driver.

One more thing, when you click on epson scan, does it bounce continouosly from the dock? if it is then look for a subfolder and install everything in it.

Keep me posted, thanks!
