Ink discharge detecting method for an ink jet recording apparatus, said ink jet recording apparatus, and an image forming device using said ink jet recording apparatus

An ink jet recording system for performing recording by scanning a carriage having an ink jet recording cartridge, at least a part of which is removably mounted to said carriage, scans a carriage along a path that has a waiting position wherein access to the cartridge is inhibited and has a replacement position wherein the removably mounted part of the cartridge can be easily accessed, and in response to a cartridge replacement signal, moves the carriage to the replacement position. When the cartridge has been replaced, the carriage is returned to the waiting position.

Ink jet cartridge replacement control

An ink jet recording apparatus has a recording mode in which recording is performed by selectively discharging black ink and color inks of colors other than black. Any abnormality in the state of discharge of the ink is performed by executing a test discharging operation. When the recording apparatus functions as a facsimile apparatus, the test discharging operation is conducted by discharging only the black ink, without discharging inks of other colors. Wasteful consumption of ink is diminished, so that the running cost of the ink jet recording apparatus is reduced.

The auxiliary member pivotally moves in a reverse direction according to the pivotal movement of the sheet material setting member when it restricted by the restricting member.

Apparatus for document setting, feeding and processing

The present invention provides a recording apparatus comprising recording means for forming an image on a sheet, discharge means for discharging the sheet on which the image was formed by the recording means, and an outer cover for convering a body of the recording apparatus. Wherein a deep recess is formed in a side wall portion of the cover, and the discharge means is arranged in a deep area of the recess, and the sheets discharged by the discharge means are stacked on a bottom surface of the recess. Whereby, the visual observation of the discharged sheet can be made more easy, the removal of the jammed sheet can be facilitated, and the recording means can easily be exchanged.

Recording apparatus

An image recording apparatus is capable of mounting a replaceable monochromatic recording head or color recording head and has a function to discriminate a type of the recording head mounted on a carriage. When a facsimile mode is selected and the mounted recording head is discriminated as the color recording head, a display is made on a display of a console panel to indicate the exchange of the recording head to the monochromatic recording head.

Image system with informing means

A sheet feeding apparatus has a support for supporting sheets, a feed roller disposed at a downstream side of the supported sheets and adapted to feed out the sheet by rotating while contacting with the sheet, and a separation roller disposed at a downstream side of the sheet supporting device in the sheet feeding direction and in a confronting relation to the sheet feed device. A slip device generates slip between the feed roller and the sheet within a predetermined range when the feed roller starts to rotate, thereby preventing the feeding of the sheet and rotating the separation roller in the sheet feeding direction.

Sheet feeding apparatus

If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, a decrease in the ink remaining or the detection of ink nondischarge can be securely made.

Ink discharge detecting method for an ink jet recording apparatus, said

A wheel for maintaining a constant distance between an ink discharge plane of a recording head and a recording sheet is provided on a carriage such that it is upstream of the recording head as viewed in the direction of movement of the recording head in a unidirectional print mode. A sensor monitors whether the recording sheet is moved off a contact of a feed roller which feeds the recording sheet to a record position and a pinch roller. Before a trailing edge of the recording sheet is moved off the contact of the feed roller and the pinch roller, bilateral recording is conducted to print in each of forward movement and backward movement of the carriage. When the sensor detects that the trailing edge of the recording sheet has been moved off the contact of the feed roller and the pinch roller, the recording is switched to unilateral printing. The print range at the trailing edge of the recording medium is thus extended.

A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU. Thereby, it is possible to detect correctly the pattern for detection of the emptiness of ink and the recording paper jam which is recorded at the trailing portion of the recording paper.
