Abstract
In an inkjet printer, when image forming operation(s) is or are interrupted, if print coverage(s) at recording paper prior to such interruption(s) is or are not more than prescribed value(s), recording medium or media undergo normal transport when operation(s) resume so as to permit image forming operation(s) which was or were underway at recording paper to resume. If print coverage(s) exceed prescribed value(s), recording paper is forcibly discharged when operation(s) resume.
Claims10
In the context of an inkjet image forming apparatus employing ink droplets jetted from one or more printheads to form one or more images on one or more recording media, an inkjet image forming apparatus characterized in that it is equipped with
- one or more interruption detection means capable of detecting one or more interruptions of one or more image forming operations;
- one or more print coverage determination means capable of determining one or more print coverages applicable to at least one of the recording medium or media at one or more times prior to at least one of the interruption or interruptions of image forming operation or operations;
- and
- one or more transport altering means capable of receiving output from at least one of the print coverage determination means and capable of, at one or more times when operation or operations resume following at least one of the interruption or interruptions of image forming operation or operations, altering one or more recording medium transport operations in correspondence to at least one of the print coverage or coverages.
In the context of an inkjet image forming apparatus employing ink droplets jetted from one or more printheads to form one or more images on one or more recording media, an inkjet image forming apparatus characterized in that it is equipped with
- one or more interruption detection means capable of detecting one or more interruptions of one or more image forming operations;
- one or more type detection means capable of detecting at least one type of at least one of the recording medium or media;
- and
- one or more transport altering means capable of receiving output from at least one of the type detection means and capable of, at one or more times when operation or operations resume following at least one of the interruption or interruptions of image forming operation or operations, altering one or more recording medium transport operations in correspondence to at least one of the type or types of recording medium or media.
In the context of an inkjet image forming apparatus employing ink droplets jetted from one or more printheads to form one or more images on one or more recording media, an inkjet image forming apparatus characterized in that it is equipped with
- one or more interruption detection means capable of detecting one or more interruptions of one or more image forming operations;
- one or more interruption time calculation means capable of calculating one or more interruption times, each such interruption time being a time elapsed from one of the time or times of interruption of image forming operation or operations to one of one or more times when operation or operations resume;
- and
- one or more transport altering means capable of receiving output from at least one of the interruption time calculation means and capable of, at at least one of the time or times when operation or operations resume following at least one of the interruption or interruptions of image forming operation or operations, altering one or more recording medium transport operations in correspondence to at least one of the interruption time or times.
In the context of an inkjet image forming apparatus employing ink droplets jetted from one or more printheads to form one or more images on one or more recording media, an inkjet image forming apparatus characterized in that it is equipped with
- one or more interruption detection means capable of detecting one or more interruptions of one or more image forming operations;
- at least two species of means selected from among the group of three species of means consisting of one or more print coverage determination means capable of determining one or more print coverages applicable to at least one of the recording medium or media at one or more times prior to at least one of the interruption or interruptions of image forming operation or operations, one or more type detection means capable of detecting at least one type of at least one of the recording medium or media, and one or more interruption time calculation means capable of calculating one or more interruption times, each such interruption time being a time elapsed from one of the time or times of interruption of image forming operation or operations to one of one or more times when operation or operations resume;
- and
- one or more transport altering means capable of receiving output from the at least two species of means and capable of, at one or more times when operation or operations resume following at least one of the interruption or interruptions of image forming operation or operations, altering one or more recording medium transport operations in correspondence to output from the at least two species of means.
