A system and a method for improving total job time without needing to know a job size. An engine dynamically decides which process speed to warm up to based on a number and size of pages currently submitted to the engine, and thus deliver the best job time dynamically. The engine also takes into account its condition and a condition of a fuser, and dynamically selects a substantially optimum point of operation.

Method and system for selecting total job time print

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.

A fuser assembly is provided with an onboard memory that may be used to store information useful in determining the conditions under which the fuser assembly has been operated. Such information can be used to better understand the root cause of fuser assembly failures, and estimate remaining fuser life, etc.

Fuser assembly including memory

A printing apparatus and method of use therefore are disclosed. The printing apparatus is usable as a replacement printer for replacing an existing printer apparatus without having to change printer drivers or make custom firmware changes in computers on a computer network. The inventive printer apparatus includes a map of source number assignments in the memory of the replacement printer apparatus for the replaced existing printer apparatus and for the replacement printer apparatus. The printing apparatus has a plurality of paper sources with each paper source being assigned a particular pre-assigned assignment code. The print request codes associated with the existing network printer being replaced must be determined. The print request codes are representative of a particular type of paper source. A map of print request codes which are sent by computers on the network for driving the existing printer are compared with the pre-assigned source number assignment of the replacement printer. If the pre-assigned source number assignment is different for any of the paper sources than the print request code, a user can change the source number assignment to agree with the print request code. These changes are placed into a table into the non-volatile memory of the printer, thereby creating a mapping of source number assignments for the new replacement printer, the old printer being replaced, and the custom firmware. The pre-assigned source number assignments can be changed using either NPA commands, the printing apparatus operations panel or using printer job language (PJL).

The bit map description for a page printer (1) from data for more lines per page than would normally fit on the page is composed by reserving the full vertical height of one line and determining the line spacing on the basis of the ratio (division) of the remaining printable page length to the number of lines less one. This is done automatically by a microprocessor (7) which determines the lines per page from the page selected from the control panel (13), performs the division (37) of lines per page less one into printable height less one, followed by page composition (39) based on the result. The data invariable fits into the mapped description without additional operator intervention.

A printer control system which enables the using application program to automatically selectively alter printer default parameters, to automatically selectively delete previously downloaded fonts and macros, and to enable the printer to operate from one of several datastream formats. The system allows the printer to initialize default parameters for a succeeding job during the printing of a current job as long as the datastream format is unchanged, and allows the deletion of downloaded fonts as long as they are not needed for the current or future pages being printed for the current job.
