Abstract
The disclosure is directed to a printer which is so arranged that a preliminary paper feeding is effected in the case of normal printing, and upon alteration of printing conditions, the preliminary paper feeding is automatically released, while, after alteration of the printing conditions, the preliminary paper feeding is again effected, and thus, a printer efficient in use has been presented, with an improved through-put in operation.
Claims4
A printer employing an electrophotographic process, which comprises:
- means for receiving data to be printed;
- a converting means for converting the received data into bit image so as to be stored in a memory;
- a print section including a photosensitive member and a paper supply section for effecting printing by transferring an image formed on the photosensitive member onto a paper sheet fed from the paper supply section;
- an output means for outputting the bit image stored in the memory to said print section;
- means for generating a paper feeding request for feeding the paper sheet from the paper supply section, to a predetermined stopping position in the vicinity of the image transfer position;
- an instructing means for instructing alteration of printing conditions;
- a control means for controlling in such a manner as to start said paper feeding request generating means before completion of processing by said converting means and to start said output means upon completion of the processing by said converting means, and
- a cancel means for canceling said paper feeding request when an alteration of the printing conditions is instructed by said instructing means, whereby the paper sheet is not fed from the paper supply section before completion of the processing by said converting means.
5 more elements
A printer comprising:
- a receiving means for receiving print data and control data;
- an analyzing means for analyzing the received data by said receiving means;
- a memory means for memorizing print data image;
- an image writing means for writing data image in said memory means according to a result of analysis by said analyzing means;
- a printing means for effecting printing;
- an output means for outputting the print data image stored in said memory means;
- a requesting means for requesting feeding of the printing medium to be used for the printing means to effect output of said output means, and
- a control means having a first mode for starting said requesting means and said output means after completion of the image writing by said image writing means, and a second mode for starting said requesting means before completion of the image writing by said image writing means and for starting said output means after completion of the image writing by said image writing means, and being so arranged that, in said second mode, the mode is temporarily changed over to said first mode by the output from said analyzing means so as to be again returned to said second mode upon termination of said output from said analyzing means.
