In my experience most Laser printers expect to receive RGB data. It’s easy to
print a standard test target in RGB and CMYK and evaluate the results, usually
the RGB shows smoother prints with better gamut.
Sending a black target as you describe is full of things to trip over while
trying to maintain a single color black. If sending from Adobe products such as
InDesign or Illustrator what are your Appearance of Black Preferences set to?
Does it treat all blacks accurately or does it send Rich blacks out?
If creating a PDF how are you managing blacks and color conversions, is the pdf
even tagged? Many factors can alter your single color blacks before it gets to
the printer.
Check with the manufacturer, often it can be found on a web site.
