HP Color LaserJet Pro 4301fdw shows a maintenance box, drum, fuser, waste toner or service message

The checks in more detail

Faded print is therefore low toner or an unseated cartridge, and streaks or spots point to the toner or the imaging drum. Read the message and the color. A color laser has four cartridges, black, cyan, magenta and yellow, and the message names the one that is low or empty. A low warning means you can keep printing, and you should order a new cartridge; a very low or replace message means that the cartridge is nearly empty or needs replacing. HP printers may continue to print past a very low message until a set override.

Open the front door, remove the named cartridge, remove the orange tape and packing from the new one, and slide it in until it clicks, and close the door completely. Use a genuine HP cartridge, since a non-HP cartridge or one with a dynamic security chip can cause a message that the cartridge is not supported. If the message persists after a new cartridge, remove it and refit it, check that the plastic tab was removed and that it is the right color and model, and clean the contacts on the cartridge and in the printer with a dry cloth.

An imaging drum message means that the drum, which transfers toner to the paper, is near its end; replace it following HP's guide. Repeating marks at a fixed interval indicate a drum problem, and spots or streaks indicate toner. Print a cleaning page from the menu or HP Smart. A message about the fuser or a maintenance kit is a service item, which HP support can arrange. Print a test page and quote the model and serial number if the message returns.
