Re: What happend with a error L3

An L3 means the lamp and mirror carriage is not comming back to the home position. Back to the left. It isn't being sensed in the home position sensor.
Are the cables on the pullies?
Have you taken the glass out and cleaned it? You can put one of the screws into the wrong place and that will hit the carriage, blocking the return.

I got an error code L3-00 on my Sharp AR-M237 can help you.

The L3-00 means that the scanner is not in home position. You can try turning off the machine and unplug it for a minute or so and then turn it on. If that doesn't work you can take off the glass and cleaning the rails the the scanner slides on and then put a slight and I mean slight layer of lubrication on the rails like ATF.

The error is for the scanner mirror home position sensor. When the scanner mirror comes back to home (start) position if the photocell sensor doesn't see it due to be dirty or faulty the L3 error will be displayed.

Hope that helps you.

Error code

The L3 code refers to your scanner not moving. One thing you can check is the scanner lock, which is a clear round dial located under the scanner bed (where you remove your copies from).
I've seen that dial get bumped into lock position when copies are removed from the recieving tray. Alot of times, I'll remove the dial to avoid that problem in the future.

Sharp AL-1641cs error L3

l3 indicates that the lens didn't make it back to home position

Sometimes just a reset will fix, other times it is a problem in optic drive or sensors

to reset enter buttons clr, exposure, clr, exposure, (must be done quickly) the display will blank, enter 14, press prnt button, then clr several times to get out and thats it.
