The DIY steps above handle the most common causes. But fuser failure, worn transfer rollers, and certain drum issues require someone to physically open the printer, check the parts, and replace what's worn.
After 25 years working on office printers and copiers, the honest answer is: most faded print problems are repairable for less than people expect. The drum, fuser, and transfer roller are all standard maintenance parts with known service lives.
