Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To decide whether the digital signals which are received via a standby communication line are normal or not or to easily monitor the state of the communication line. SOLUTION: A fact that a specific pattern is detected can be displayed at the outside and can be referred to from the outside is held by a pattern detection holding circuit 4 every time the specific pattern is once detected out of the digital signals received from a standby communication line by a specific pattern detection circuit 2 after the specific pattern is collated with a preset collation pattern that is sent from a specific pattern setting circuit 3 in a hunting state. Then the hunting state is shifted to a non-hunting state. When the specific pattern is not detected at every prescribed cycle in the non-hunting state, the holding state of the circuit 4 is canceled and then the non-hunting state is shifted again to a hunting state.

Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain a fixing method which is capable of rapidly execute fixing an unfixed image and provides a high image density by blowing ozone to the unfixed image to increase a fixing rate. SOLUTION: The ozone is blown to the unfixed image in the method for fixing the image to an image forming medium.

Particularly if at least part of this nonaqueous solvent is fats and oils having an unsaturated bond of, for example, >=109 Ω.cm in electric resistance and <=3.5 in dielectric constant, the fixing time may be improved when blowing the ozone. Additionally, the image is fixed by the chemical change of the unsaturated bond in the solvent and, therefore, the splashing of the solvent vapor at the time of fixing as with the conventional liquid developer does not occur and the fixing is clean.  Since the fixing without using heat is possible, energy conservation is resulted and there is no need for standby time.
