Hi,
First ty printing the demo page using the below procedure:
Printing a demo page will make sure that the printer is operating
correctly.
To print a demo page:
In ready mode, press and hold the
On Line/Continue button on the control panel for 2 seconds to print a demo page.A demo page showing the printer’s features and capabilities is printed.
If the demo page gets printed correctly then, you have check the printer settings whether the quality is set to normal or best quality..
If the demo page
doesn't get the colors perfectly, try removing the toners and try
shaking it and installing, as it helps in redistributing the toner to spread evenly..
Still if you have problem then , try downloading the manual from the below link

The page number 54 or section 7.12 helps to correctly identify, what type of printing quality problem
you have and it helps to solve it easily
Please leave me comment, if you need further assistance
