We use a number of different HP Laserjet printers (lj1320, lj2430, lj3055, lj4000, lj4100, lj4350). When we get the "Perform printer maintenance" message we order a maintenance kit and install it. Most of the time the printer isn't experiencing an issues. Is it necessary to install a maintenance kit immediately or can we let it go for a say 3-6 more months, or until we start seeing print quality or paper feed issues? What do you do? What are your opinions?
We also have a printer shop in town that usually keeps maintenance kits in stock, so it's usually not an issue to get it soon if we need it.
