Black Copy/Inbox Print Jobs> is set to 'On'.
To copy or print in black-and-white, press [Allow Black Copy/Black Inbox Print].

• If you set <Allow Printer Jobs with Unknown IDs> to 'On', all print jobs are accepted. Therefore,
the Allow Black Printer Jobs setting is ignored.

a document, or use other functions except for black-and-white copying and printing, you must
insert a control card.
