20100157328 | PRINTING APPARATUS AND DRIVING FORCE TRANSFER CONTROL METHOD - This invention is directed to a printing apparatus capable of reliably performing a driving switching operation using movement of a carriage. In the printing apparatus, it sometimes cannot be determined to which of a clutch lever or the cap of a printhead the carriage abuts against. In this case, even if the carriage abuts against the cap, a position where the abutment was detected is regarded as the temporary home position of the carriage. When a conveyance motor is driven to transfer its driving force to a desired engaging destination, the cap is retracted from the moving path of the carriage. The driving force of the conveyance motor can thereby be transferred to the desired engaging destination. | 06-24-2010 |
