Abstract:

A method for increasing the waste ink storage capacity in an ink jet printer includes the steps of providing a printer frame including a first frame portion and a second frame portion; providing a platen extending between the first frame portion and the second frame portion; providing a maintenance station coupled to the first frame portion; providing a printhead carrier for carrying a first printhead and a second printhead, and adapted for reciprocating movement along a carrier path, the carrier path extending over the first frame portion and the platen; defining a first ink spit area located at the maintenance station; defining a second ink spit area located at the platen; and selectively controlling an operation of the first printhead during spitting operations to eject a first ink in the first ink spit area and selectively controlling an operation of the second printhead during spitting operations to eject a second ink in the second ink spit area.

International Classification:

G01N 2186

US Classification:

2505594, 25055916

Abstract:

A media sensing apparatus includes a media sensor including a light source for generating a light beam, and a diffuse detector positioned in relation to the light source for detecting diffuse light components reflected from a sheet of print media. A media support is provided having a detection portion. The detection portion is located such that the media sensor faces the detection portion. The detection portion is configured to direct specular light components reflected from the detection portion to the diffuse detector in an absence of the sheet of print media being interposed between the media sensor and the detection portion.

US Classification:

2505594, 25055916, 356431, 347 19

Abstract:

An imaging apparatus includes a media support surface. A light source and a light detector are positioned in relation to a reflective surface such that when a sheet of print media covers the reflective surface, a reflected specular light component of a light beam is received by the light detector, and when the reflective surface is not covered, the reflective surface directs the reflected specular light component of the light beam away from the detector. The signal strength of the output from the light detector when receiving a diffuse light component reflected from the reflective surface is less than the signal strength of the output from the light detector when receiving the reflected specular light component that is reflected from a low reflectance print media.

International Classification:

H04N 1/04

US Classification:

358474, 358475, 358488

Abstract:

An illuminated media position indicator for an imaging device comprises a scanner having a scanner top cover including an inner edge portion which defines an opening for a scanning platen disposed adjacent the opening. The inner edge portion defines at least one corner corresponding to a scan origin. An illuminated registration corner is positioned in said at least one corner corresponding to the scan origin and comprises at least one LED in optical communication with the illuminated registration corner. The illuminated registration corner communicates light from the at least one LED throughout the illuminated registration corner using substantially total internal reflection to indicate media position and orientation at said scan origin.

International Classification:

G06K 15/02

US Classification:

Abstract:

A method for calibrating the printing of a lenticular image with respect to the lenticules of a lenticular sheet includes the step of printing a test pattern including a plurality of patches on a lenticular sheet with an ink jet printer. The patches are sensed though the lenticules with a sensing device and the sensed data is analyzed to determine a calibration factor that is used to subsequently print a lenticular image on the lenticular sheet. In a further embodiment, the method comprises aligning a lenticular sheet in the ink jet printer; sensing the lenticules on said lenticular sheet with the sensing device; analyzing the sensed data in the processing unit to determine the lenticule spacing; calculating a calibration factor based upon the analysis; and using the calibration factor to subsequently print a lenticular image.

G03G 15/00

US Classification:

399 16, 399 23

Abstract:

A method for detecting a media change includes the steps of comparing a previous media condition to a current media condition, detecting a media change when the previous media condition is in one state and the current media condition is not that one state and, prompting a user to make appropriate menu selections when the media change is detected.

Inventors:

Charles Simpson - Lexington KY, US

International Classification:

B41J 2/01

US Classification:

347101000

Abstract:

A method of and apparatus for printing a borderless image from original image data on a medium having medium dimensions and at least one medium tolerance. The method comprises the acts of determining a ratio between two dimensions of the original image data, determining a sum between the at least one medium tolerance and one of the medium dimensions, stretching one of the image dimensions to at most equal to the sum; and stretching the other image dimension based on the ratio and the increased image dimension. The printing apparatus comprises a ratio transformer to determine a ratio between two dimensions of the original image data, and to determine a sum between the at least one medium tolerance and one of the medium dimensions and an image transformer to stretch one of the image dimensions to at most equal to the sum, and to stretch the other image dimension based on the ratio and the stretched image dimension.
