Improved printer enabling concurrent writing, transferring, and fixing operations on the same sheet of recording material

A printer comprising:

• an endless belt latent image carrier, said endless belt having a width dimension shorter than a length dimension of a sheet of recording material to be printed upon;
• a carriage moveable parallel to a lengthwise dimension of said endless belt;
• a latent image forming means including an image writing means mounted on said carriage, said image writing means for selectively energizing a portion of said endless belt to form a latent image on said endless belt when said belt is held motionless during a write operation;
• a developer means fixed in position for forming a toner image, corresponding to said latent image, on said endless belt;
• a transferring means mounted on said carriage for transferring said toner image from said endless belt to said sheet of recording material to be printed upon;
• a fixing means mounted on said carriage adjacent to said transferring means for fixing said toner image transferred to said sheet of recording material;
• an endless belt transporting means for transporting said endless belt in its lengthwise direction, said transporting means holding said endless belt motionless during said write operation, a transfer operation, and a fixing operation, said endless belt transporting means transporting said endless belt its full length during two of said writing operations;
• a recording material transporting means for transporting said sheet of recording material in a direction perpendicular to the direction of movement of said endless belt, said recording material transporting means moving said sheet of recording material intermittently in increments and holding said paper motionless during said write operation, said transfer operation, and said fixing operation;
• a carriage transporting means for transporting said carriage parallel to a lengthwise dimension of said endless belt, said carriage transporting means for moving said carriage with respect to said endless belt during said write operation, said transferring operation, and said fixing operation when said endless belt is held motionless;
• and
• an activating means for selectively activating said latent image forming means, said transferring means, and said fixing means so that after three write operations, as said carriage is moved with respect to a motionless endless belt, said image forming means forms a first latent image on said endless belt concurrently with said transferring means transferring a toner image to said sheet of recording material and concurrently with said fixing means fixing a previously transferred image to said sheet of recording material.
