Title: Printer
Inventor: MASAKI HIDEO
IPC: B41J29/38
Filed: 1986-12-26
Abstract: PURPOSE:To prevent deterioration of printing quality and breakage of a printing head by cooling the printing head when a high temperature condition of the printing head is detected and giving a printing pause time which increases in proportion to a high temperature duration of the printing head while the printing heat is cooling. CONSTITUTION:When a detection signal sent from a temperature sensor is checked by printing line interval, and a detection signal is set to a 'H' level in which a printing head is at a high temperature exceeding a limit temperature, both-way printing is changed to one-way printing. If a detection signal from the temperature sensor is set to 'H' level through next checking, a single line is printed in the one-way printing mode and a 'T' sec printing pause is given after LF. Further, if the detection signal from the temperature sensor is at 'H' level through checking next to the above-mentioned checking, a '2T' sec printing pause is give. Subseqnetly, the printing head which is in high- temperature condition is always given sufficient printing pause for cooling and printing is resumed from a next line, thus causing no deterioration of printing quality or breakage of the printing head.
