Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
A printer (102) that prints on a plurality of sheets, the
printer comprising: a. a gloss meter (121) that, prior to printing each sheet of the
plurality, provides a first measurement at a respective first time and a second
measurement at a respective second time, the meter comprising: (1) a light source (216); (2) a reference surface (124); and (3) a light detector (222), the first measurement being
responsive to light detected during the first time reflected from the
reference surface (124); b. a handler (120, 126) that routes each sheet, each sheet
interposed between the meter (121) and the reference surface (124) during the
second time, the second measurement being responsive to light detected during
the second time reflected from each respective sheet; c. a print engine (130) that receives each sheet from the
handler (126); and d. a control system (110) that receives printing control data,
directs operation of the print engine (130) in response to the data, and adjusts a
parametric setting of the print engine in response to the first measurement, and
the second measurement (522, 532).
Claim 2
Dependent Claim
116 words
A printer that prints on a provided sheet, the printer (102)
comprising: a. a reference surface (124, 320) cleaned by contact with the
sheet (410); b. a gloss detector (122) responsive to a first reflection from
the surface (124) and to a second reflection from the sheet (410); c. a controller (110), coupled to the detector (122), that
provides a signal (128) responsive to a ratio of the first reflection and the
second reflection (522); d. a print engine (130) that prints on each sheet (410); and e. a sheet handler (120, 126, 320, 132) that routes each
sheet (410) through the print engine (130) at a velocity responsive to the signal
(128, 532, 534, 536).
Claim 3
Dependent Claim
101 words
A printer (102) that prints on a provided sheet, the printer
comprising: a. a reference surface (124) cleaned by contact with the sheet; b. a gloss detector (122) responsive to a first reflection from
the surface (124) and to a second reflection from the sheet; c. a print engine (130) that prints on the sheet in response to a
signal (128, 532); and d. a controller (110), coupled to the detector (122), that
provides the signal (128) for adjusting a parametric setting of the print engine
(130) in response to a ratio of the first reflection and the second reflection
(522).
Claim 4
Dependent Claim
26 words
The printer of claim 2 wherein the gloss meter (121)
comprises a body (210) having an integral source tube (212) and an integral
reflection tube (214).
Claim 5
Dependent Claim
28 words
The printer of claim 2 further comprising a sheet handler
(120, 126, 320) responsive to the controller (110) for moving each sheet
individually across the reference surface (124).
Claim 6
Dependent Claim
36 words
The printer of claim 4 wherein the handler (120, 126, 320)
routes each sheet at a first velocity during the second time and at a second
velocity greater than the first velocity after the second time.
Claim 7
Dependent Claim
18 words
The printer of claim 4 wherein the handler comprises a
registration roller (320) comprising the reference surface (124).
Claim 8
Dependent Claim
21 words
The printer of claim 2 wherein the signal (128) is responsive
to a comparison of the ratio to a threshold (522).
Claim 9
Dependent Claim
26 words
The printer of claim 7 wherein the controller (110) further
comprises an input channel (104, 106) that provides a second signal (108) that
identifies the threshold.
Claim 10
Dependent Claim
21 words
The printer of claim 2 wherein the print engine (130)
comprises a fuser having a temperature responsive to the signal (128).
