30.01.45 Scanner Failure CM4540MFP

[KC721]

I keep getting this error message when i try to scan.  I can copy without problems.  Once in a while when i try to fax, i get this message but mostly when i try to scan to a folder on my computer.  I turn the printer off, and sometimes after that i can scan.  Sometimes i have to turn it off twice, let it warm up and then copy a page.  Then i can scan.  It is happening more often now.  Printer is only 3 years old.

I will try this, but am learly.  I believe this formatter costs about $500 to replace?
