Abstract
A multifunctional printer retains image data in an image memory when paper runs out during a copying operation, until another operation is requested or a predetermined time period expires. Also, the multifunctional printer retains information of the document that has not been recorded in a RAM when erasing the image data. Then, the information is displayed on an operation panel when the document needs to be re-scanned in order to enable the user to re-scan the document.
Claims15
A multifunctional printer that can perform a copying operation and at least one other operation, the printer comprising:
- a memory that stores an image of a scanned document and document managing information;
- an image recorder that performs a copying operation based on the image stored in said memory;
- and
- a controller that erases the image stored in said memory when the at least one other operation is requested and when recording paper has run out during a copying operation of said image recorder, releases said memory for the at least one other operation, retains the document managing information necessary for re-scanning the document, and enables re-scanning of the document according to the document managing information when recording paper is loaded.
