Copier Prints Pdf files in color even when all defaults are set to B&W
As this is only affecting PDF's, in my experience with exact same symptom, it was always to do with the 'Print as image' tick box within acrobat reader. It is especially required if the document was originally something else and converted to PDF. This is only needed from acrobat reader version 8.0 onwards. Previous versions were never affected.
Example, I had a client yesterday with a color quality problem on a new MX color machine. Output print was terrible in color quality compared with the design on the PC. All other pictures, documents, designs etc etc were great, only this PDF was going mental.
Tick box 'Print as image', tested same problem PDF perfectly. Their IT dept knew nothing about it. They were able to print the PDF ok on a HP CLJ, but their Sharp and another Canon color machine just couldnt handle it before the box was ticked within reader.
