System, method and print cartridge for signaling user replacement of fuser wiper
View Patent ↗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 (b 0 , b 1 ) 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.
1. A method of signaling user replacement of a fuser wiper within a printer that prints using a toner cartridge having a memory device, the method comprising the steps of:
storing information pertaining to specified points when said fuser wiper should be replaced in said memory device;
a print engine of the printer retrieving said information from said memory device;
printer logic causing a notification message to be generated based on said information stored on said toner cartridge, said notification message indicating to a user that said fuser wiper should be replaced; and
determining when said notification message should be generated as a function of a specified interval necessary for fuser wiper replacement,
wherein said specified interval is related to a variable selected from the group consisting of: the amount of toner remaining in said toner cartridge, the type of media utilized, and a type of said toner cartridge.
2. A image forming system supporting a signaling function for notifying user replacement of a fuser wiper within a printer comprising:
a print cartridge;
a fuser assembly for receiving media upon which toner from said print cartridge has been deposited, said fuser assembly including a fuser wiper;
a memory device for storing print related information;
a print engine communicably coupled to said print cartridge; and
process logic for causing said print engine to read said information from said memory device and for generating a notification message to a user indicating the fuser wiper should be replaced at some specified point in the print cartridge's life,
wherein said process logic determines whether said print cartridge supports a replace fuser wiper message function.
3. An image forming system supporting a signaling function for notifying user replacement of a fuser wiper within a printer, comprising:
a toner cartridge having a memory device storing information pertaining to specified points when said fuser wiper should be replaced;
a fuser assembly for receiving media upon which toner from said toner cartridge has been deposited, said fuser assembly including said fuser wiper;
a print engine communicably coupled to said toner cartridge;
process logic for causing said print engine to read said information from said memory device and for generating a notification message to a user indicating the fuser wiper should be replaced; and
a display operably coupled to said process logic and adapted for graphically displaying said notification message to a user,
wherein said process logic determines the appropriate time for generating a notification message as a function of specified intervals necessary for fuser wiper replacement, and
wherein said specified intervals are related to a variable selected from the group consisting of: the amount of toner remaining in a toner cartridge, the type of media utilized, and the type of toner cartridge.
