Abstract: A printing device (10) such as a laser printer includes a fuser assembly (200) with a fuser wiper (210) that can be removed and replaced by a user during normal maintenance to extend the useful life of the fuser assembly (200). Indicators (b0, b1) stored in a memory device (144) can be read by a print engine (36) of a printer (10) either when a print cartridge (100) is first inserted into the printer (10) or at specified times thereafter. Depending on the contents of the memory device (144), the print engine (36) may send a notification message to the printer's raster image processor (150) to cause a message to be displayed on the printer's operational/display panel (254) that informs a user the fuser wiper (210) should be replaced.

Abstract: An improved electrophotographic printer is provided for generating a security stamp in firmware, and printing that security stamp to create documents that have a visible and tactile logo that is automatically printed on each page of a print job. The firmware will automatically create the proper bitmap of the security logo for a page's print resolution and bit depth. Using a color laser printer, the security stamp can be printed using all of the process colors, such as CMYK, which would be rendered and printed at 400% toner coverage. This gives the security stamp a very dark visible appearance and a thick tactile texture. The security stamp can include an area for printing a serial number of the printer, and for printing a time and date stamp.
