In an attempt to correct an ongoing scan issue, I recently installed a firmware update which I found
has a defect.V 52.005.23 JUL18 2014 should not be used. When installed and attempt is made
to print from a pdf file you may get a message ... you need to install a printer. On occassion this can
be overcome by finding a pdf file which does not produce this message and thereafter go back to the
original pdf which may then work.
The previous firmware was v 52,004,26,000 which did not have this problem.
I am looking for a procedure to remove the defective firmware and then reinstall the non defective one.
