Abstract:

A printing device () such as a laser printer includes a fuser assembly () with a fuser wiper () that can be removed and replaced by a user during normal maintenance to extend the useful life of the fuser assembly (). Indicators (b, b) stored in a memory device () can be read by a print engine () of a printer () either when a print cartridge () is first inserted into the printer () or at specified times thereafter. Depending on the contents of the memory device (), the print engine () may send a notification message to the printer's raster image processor () to cause a message to be displayed on the printer's operational/display panel () that informs a user the fuser wiper () should be replaced.
