Black Finish
This setting determines Black Toner usage only.
Auto
This option is best for an office environment, with the printer
determining which style is better.
Matte
This option uses more Black and less CMYK while producing a flatter
black.
Black Overprint
This option prevents registration errors and only works for 100%
black text.
1. Click on the checkbox to enable the option.
Collate
Collating can be carried out with or without a hard disk drive installed.
However, printers with a hard disk drive will provide greater
performance. This option is useful when printing multiple copies of
large documents and you want to print them in sequence.
1. Click to enable collation of your documents.
