Abstract
Official abstract text for this publication.
A printing apparatus conducts inspection associated with printing by changing a relative positional relationship between a line print head and a sheet feeding position for a sheet in a direction perpendicular to a direction in which the sheet is fed, forming an image on the sheet using the line print head a plurality of times, and reading the formed images using a reading unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: providing a print head of a line-type having an array of recording elements arranged in a direction including a vector of a second direction perpendicular to a first direction in which sheets are conveyed; providing a sensor having an array of photodetectors arranged along a sensor length including a vector of the second direction; and performing a print mode in which actual images are formed with the print head using a first sheet t…
