Abstract
When a paper jam is detected, in the case where the cause of the paper jam is a CR motor error in which the speed of the carriage is decreased by as much as a load when the paper jam occurs and becomes equal to or less than a set speed, when there is an instruction to continue printing, cleaning is performed on a printing head. In this case, it is determined whether the paper position is particularly in a one-side supporting range in which the paper is supported by only one pair of transporting roller pairs provided in each of an upstream side and a downstream side of a transporting direction of the paper with interposing of a moving path of the printing head. Then, it is preferable that cleaning be performed as long as the paper position is in the one-side supporting range.
Claims7
A printing apparatus comprising:
- a driving unit that moves a carriage having a liquid ejecting head which ejects liquid to a printing medium;
- a cleaning unit that performs cleaning on the liquid ejecting head;
- a detecting unit that detects a jam of the printing medium based on change in operation of the carriage;
- a control unit that controls the driving unit to move the carriage and stops the driving of the driving unit to stop the carriage movement when the detecting unit detects the jam;
- an instruction unit that is operated to give an instruction to continue printing after the jam is released;
- and
- a cleaning control unit that causes the cleaning unit to perform cleaning on the liquid ejecting head when the instruction to continue printing is given from the instruction unit.
A printing apparatus comprising:
- a driving unit that moves a carriage having a liquid ejecting head which ejects liquid to a printing medium;
- a cleaning unit that performs cleaning on the liquid ejecting head;
- a jam detecting unit that detects a jam of the printing medium;
- a direction determination unit that determines a moving direction of the carriage;
- a carriage control unit that controls the driving unit to move the carriage and withdraw the carriage in a reverse direction of the moving direction of the carriage at the time of the jam detection determined by the direction determination unit when the jam detecting unit detects the jam;
- a capping unit that is capable of capping the liquid ejecting head provided in one end in a movement path of the carriage;
- an instruction unit that is operated to give an instruction to continue printing after the jam is released;
- and
- a cleaning control unit that causes the cleaning unit to perform cleaning on the liquid ejecting head in the case where the carriage is withdrawn in a position opposite to the capping unit, and the cleaning control unit causes the cleaning unit not to perform cleaning on the liquid ejecting head in the case where the carriage is withdrawn in a position of the capping unit side, when the instruction to continue printing is given from the instruction unit.
A printing method which performs printing by ejecting liquid to a printing medium from a liquid ejecting head while a carriage reciprocates, the method comprising:
- detecting a jam of the printing medium based on change in operation of the carriage;
- stopping the carriage movement when the jam is detected in the detecting of the jam;
- and
- causing the cleaning unit to perform cleaning on the liquid ejecting head when an instruction to continue printing is given from an instruction unit after the jam is released.
