Abstract
An image forming apparatus to prevent that the reception operation is interrupted. The image forming apparatus having a cassette for storing sheets, detecting member for detecting the quantity of sheets in the cassette, recording portion for recording images on a sheet, and controler for prohibiting the recording image by the recording portion when the detecting member detects a quantity of sheets that is less than a predetermined quantity.
Claims19
An image forming apparatus comprising:
- a sheets cassette which stores sheets;
- a detector which detects whether a quantity of remaining sheets stored in said sheets cassette is less than a predetermined quantity or not;
- a receiver which receives image data;
- a recording device which records images on the sheets stored in said sheets cassette in accordance with said received image data;
- and
- a controller which prohibits the recording of image data by the recording device based on the image data received by the receiver at an end of a currently recording job after the detector detects that said quantity of remaining sheets is less than the predetermined quantity.

An image reading apparatus comprising:
- a receiver which receives image data;
- a sheets cassette which stores sheets;
- a recording device which records images on the sheets stored in said sheets cassette in accordance with said received image data;
- a detector which detects whether a quantity of remaining sheets stored in said sheets cassette is less than a predetermined quantity or not;
- a memory which stores said image data;
- and
- a controller which controls said recording device, wherein said recording device is prohibited from recording the image data and said received image data is stored in said memory when the detector detects that said quantity of remaining sheets is less than the predetermined quantity before said recording device starts recording the images, and wherein said recording device records the image continuously until the recording of a currently recording job is completed even if the detector detects that said quantity of remaining sheets is less than the predetermined quantity after said recording device has started recording the images, and then prohibits recording the image data following the image data of the currently recording job.

An image forming apparatus comprising:
- a sheets cassette which stores sheets;
- a first detector which detects whether a quantity of remaining sheets stored in the sheets cassette is less than a predetermined quantity or not;
- a second detector which detects whether the sheets cassette is empty or not;
- a receiver which receives image data;
- a recording device which records images on the sheets stored in the sheets cassette in accordance with the received image data;
- and
- a controller which controls said recording device, wherein said recording device continues to record the image data of a currently recording job until completion thereof and then prohibits recording the image data following the image data of the currently recording job when the first detector detects that the quantity of remaining sheets is less than the predetermined quantity, and wherein said recording device prohibits recording the image data of the currently recording job at the end of a currently recording page when the second detector detects that the sheets cassette is empty during the continuation of the recording of the currently recording job.
