Hello, what is wrong with my printer, there is a light on, not any of the toner colors, not the wireless one, BUT the one has arrows going to the right and left and then a triangle?

Hi.
On the drums for each colour there is a purple/blue/green slider for cleaning the corona wire. If there is a stripe of colour anywhere on the page going from top to bottom check these sliders. They need to be where the arrow on the slider meets the arrow on the drum casing.

As for low toner on the Yellow and Magent - Replace the cartridges.

Check the yellow toner cartridge, printing a configuration page.

Configuration page
The Configuration page lists the current settings and properties of the printer. You can print a
Configuration page from the printer or HP Toolbox. To print the Configuration page from the printer,
complete the following steps.
1 Press the (LEFT ARROW) or the (RIGHT ARROW) buttons to select the Reports menu.
2 Press the button (SELECT).
3 Press the (LEFT ARROW) or the (RIGHT ARROW) buttons to select Config report.
