Most Colour machines have three settings.

Auto Colour, Machine will determine if the original is Colour or Black and White from its scan. Then print in the format that best suits the original.

Full Colour, Machine will copy in full Colour regardless of Original type.

Black and White, Machine will copy or scan in B & W regardless of original type.

Hope this is of some help.

When the printer dialog box pops up, click the properties button and you can select Black only there and your copy will print in black ink only.

That's a process problem with that machine.
May require a service call .ON and OFF is pretty much all a customer can do and wait for it to setup.
NOTE: The problem occurs because of the trickle development system in the machine, making extended lengths of black and white copies / prints does not allow the black developer housing to purge itself of excess waste Toner (Dry Ink) and Developer. There are two solutions for the problem:

• Make 1,000 copies / prints of a black and white job, then make 150 copies / prints of full color. Continue making 1,000 copies / prints of the black and white job, then 150 full color, and so on, until the entire black and white job is complete.
• Make extended jobs in groups of 100 by making 100 copies / prints of the black and white job, then allowing the machine to cycle down (return to 'Ready') and making the next 100 copies / prints. Continue in this pattern until the entire black and white job is complete.

NOTE: The above solutions are based on jobs using 8.5 x 11 inch paper, single sided, with no more than 28% coverage.
