It is important to install maintenance kits in LaserJet Printers, when the message shows up on the printers’ operator panels. I have worked with customers over the years that decide to only have the fuser assembly replaced or none of the parts replaced and then have the maintenance page count register cleared. It is true that in many cases all of the parts that are replaced with a maintenance kit have not started to fail and it is cheaper to just replace the fuser or no parts at all in the short term. But, in the long run it will cost you more.
OEM engineering departments have determined the optimum life expectancy of the parts in a maintenance kit. When a kit is not replaced at once, the separate parts will most likely all fail over a couple to a few months later. This results in a few service calls with labor charges and having to pay for eventually all of the parts that come in a maintenance kit separately at a higher cost than the cost of the complete set.
The best course of action when the LaserJet Printer Operator Panel states that it is time for maintenance is to have a call logged for your printer to have the entire kit replaced. Again, in the long run it will cost you the least! Most all LaserJet Printer Maintenance Kit display trigger times are 150,000 to 325,000 pages of print at 4% to 5% fill.
