My laser jet III says 50 Service. What does that mean?
the fuser assembly is not heating up in the time alloted. This is usually due to bad power and the power supply would need to be replace, thouth it’s common to replace the fuser at the same time if there is any wear. For the price of service, you can get a “swap”.. a completely refurbished HP LaserJet Serier III that has had both these parts (and others) replaced and is warranted for a full year. You might also want to upgrade to a newer refurbished LaserJet printer. We have hundreds of models to choose from. Call Landmark at 800-466-5687.
