Hello,

The scanner is busy, try again later, this message may be related to a communication issue between the computer and the printer.

In order to palliate this incident, please restart the printer, computer, and router.

1. Turn the printer off, and then wait 10 seconds.
2. Disconnect the printer power cord from the printer.
3. Turn off the computer or the device you are trying to print from.
4. Connect the printer power cord to the printer, and then turn on the printer.
5. Disconnect the power cord from your wireless router, and then wait 30 seconds.
6. Reconnect the power cord to the router.

   NOTE: Wait until internet service is restored. Internet service is interrupted while the router is off.

7. Wait at least 3 minutes, then turn on the computer.
8. Try to scan.

I remain at your disposal in case of need.

Best regards,

Hi,

Thanks for your help.  Having spent almost two hours trying to sort the problem yesterday I couldn't face it again until now.  When I switched it on again and scanned it did!
