Auto Tray Switch; Paper Size Check; Multi Purpose Tray Is Manual Feed; Always Create 100% Black(K) Toner - Oki C5150n Technical Reference Manual

Auto tray switch

If two trays contain identical print media, the printer can
automatically switch to the other tray if the media runs out in the
middle of a print job. If you will be using different media in the
different trays, deselect this.

Paper size check

Deselect this if you do not want the printer to check to see if the size
paper loaded in the selected tray matches that required for the
document being printed.

Multi Purpose Tray is Manual feed

Select the option desired. The default is No.

Always create 100% Black(K) Toner

Normally the printer uses all four toner cartridges to print black text.
Use this to set the printer to always print black text using only the
black toner cartridge.

Run maintenance cycle before printing

Use this to generate a cleaning page which runs through the printer
before the job is printed. This should eliminate any fading, streaking
or erratic marks from the printed pages.
