"Scanning in progress" reported even when I'm not scanning anything

I've been using my AL1642CS connected by USB to my Windows XP Pro desktop for about a year now - very reliably - both for printing and for scanning. I love the duplex print feature, so much easier on the trees!

I've also printed to it through the USB port on my network router - but then I can't use it for scanning since Microsoft never enabled network scanning - only network printing!

Clean the scanner glass if no change , format the computer and install the softwares again but firs you can test with another computer.

it would have spilled toner on the laser unit glass which can be accessed after removing the developer & drum units. Its on the upper part inside the machine in the drum chamber.

Not familiar with that model but what I would try is to turn off the copier remove the glass and try moving it by hand, then turn it on and see what happens it may have a bad motor

pull both trays out.....have a look in tray 2, is there a switch sensor actuator hanging down yes........is there a similar one in tray one?
No? They get knocked off and lost very easily

if scanner is not going all the way back you need to ck the home posinson senser it may be dirty.
