Filed: 1990-02-01
Abstract: PURPOSE:To prevent damage or sticking of an ink sheet from happening by a method wherein when the recording motion is interrupted during recording of image data, after heating an ink sheet, the ink sheet and a recording medium are separated by carrying the recording medium by a designated quantity. CONSTITUTION:When communication interruption is detected, data in which the whole of one line is black is transferred to a thermal head 13. Then, power is connected with a heating resisting element 132 by single block unit, and the heating resisting element 132 of the thermal head 13 is heated so that the temperature of an ink layer on an ink sheet 14 may not decrease. Thus, under a condition where the temperature of the ink layer is kept at a high temperature, carrying, cutting and delivery of a recording paper 11 are performed. Thus, separation between the ink sheet 14 and the recording paper is made easier by connecting power with the thermal head 13 to heat it so that the temperature of the ink layer may not decrease when communication is interrupted and the recording motion is stopped, and then carrying the recording paper 11. By this method, damage, etc. of the ink sheet 14 due to sticking to the recording paper 11 can be prevented from happening.

Title: Printer
Inventor: HONMA YUTAKA
IPC: G06K15/00
Filed: 1986-01-31
Abstract: PURPOSE:To avoid the contamination of a ribbon and the remarkable decrease in throughput, by a method wherein the transfer of a carriage and the operation of a printing head are once stopped when the supply voltage decreases and the printing is carried out under a state in which the transfer speed of the carriage and the operation speed of the printing head are lowered. CONSTITUTION:When the printing of a high density is started, the output voltage of a power source is lowered at a time point when the printing proceeds to a certain extent. This is detected by a power source output voltage detection circuit 7 and CPU 1 outputs the command by which the printing is once stopped to a carriage control circuit 2 and a printing control circuit 4. Then, the command by which the printing speed is lowered is outputted and the printing is again started in a state where the printing speed is lowered at the position where the printing is stopped. At the time point when the transfer of the carriage is once stopped, a command is outputted by CPU 1 in order to spread the interval of pulses of printing signal and the printing is again started. Just before or after transferring to the subsequent line, the control is carried out so as to return to ordinary printing speed. Therefore, the blank feed in the reverse direction of the carriage is never performed and the contamination of a ribbon does not occur.
