On OSX, multifunctional printers such as MF8280CW may display an error message along the lines of:
Cannot scan because of the following: - Scan type set on the scanner is incorrect - Scanner is busy - Error occurred in the scanner - Scanner is in Sleep mode Check the scanner status and try again. Scanner driver will be terminated. Error code: 2100010
when attempting to scan a document. The workaround is to use the printer's menu and counter-intuitively select
Select scan type→Remote scanner (instead of
Computer). The printer will display
Waiting… and then on OSX any software can used to scan.
