Patent ID: 8294956

Claim:
An apparatus for affixing and using non-visible printed marks with clear toner, the apparatus comprising: a paper accumulator adapted to receive at least one associated sheet of printed paper and hold the at least one associated sheet in a stack; an inline spectrophotometer attached to the paper accumulator and being adapted for detecting and then reading the mark with clear toner when the at least one associated sheet is contained in the paper accumulator, the inline spectrophotometer detecting a presence of the mark with clear toner on the at least one associated sheet in the stack indicating that a condition is met for prompting movement of the stack to a peripheral device for completing a finishing operation; a computer operable database containing information related to an instruction to be performed on the stack when a condition is met; a means for comparing the inline spectrally sensed mark that is received from the inline spectrophotometer with the information in the computer operable database, the means being further adapted to send the instruction to a peripheral device when the condition is determined as being met; and a peripheral device inline with the system, the peripheral device adapted for performing the instruction contained in the computer operable database.
