Abstract

Abstract An intelligent printing system (110). The overall system has a light-imaging subsystem (120), an electrophotography subsystem (130) and a printing substrate subsystem (140). The system processor (126) monitors all of the characteristics of the system, including toner content and quantity, photoreceptor wear and usage, heat of the fuser, quantity of printing substrates remaining, power of the light source, and profile of a spatial light modulator. The monitored processes are used to adjust the printing process so that the maximum print quality is achieved. Additionally, the information received assists in maintaining the highest level of quality functioning of the system through the maintenance cycle.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 144 words
A printing system comprising: a. a light-imaging subsystem; b. a EP subsystem including: i. at least one photoreceptor operable to receive light from said light-imaging subsystem; ii. at least one toner dispenser operable to dispense toner to photoreceptor, wherein said toner dispenser includes monitoring capability and is operable to transfer said toner to said photoreceptor; iii. an interface with said light-imaging subsystem through which said light can pass; iv. a transfer port for transferring said toner to printing substrates; c. a substrate-handling subsystem wherein said at least one photoreceptor transfers toner to a printing substrate through said transfer port; and d. a processor for continuously adjusting operation of said system in accordance with data received from said EP subsystem, wherein said adjustment includes controlling numbers and selection of gray levels and colors available to a user and notification of system failures for said user.
Claim 2
Dependent Claim 144 words
A printing system comprising: a. a light-imaging subsystem; b. a EP subsystem including: i. at least one photoreceptor operable to receive light from said light-imaging subsystem; ii. at least one toner dispenser operable to dispense toner to photoreceptor, wherein said toner dispenser includes monitoring capability and is operable to transfer said toner to said photoreceptor; iii. an interface with said light-imaging subsystem through which said light can pass; iv. a transfer port for transferring said toner to printing substrates; c. a substrate-handling subsystem wherein said at least one photoreceptor transfers toner to a printing substrate through said transfer port; and d. a processor for continuously adjusting operation of said system in accordance with data received from said EP subsystem, wherein said adjustment includes controlling numbers and selection of gray levels and colors available to a user and notification of system failures for said user.
Claim 3
Dependent Claim 25 words
The system of claim 1 wherein at least one component of said EP subsystem has active monitoring capabilities that are in communication with said processor.
Claim 4
Dependent Claim 22 words
The system of claim 1 wherein said processor must calculate the operating parameters of at least one component of said EP subsystem.
