Abstract
An ink jet printer includes a print head, a carriage on which the head is mounted, and a maintenance mechanism for the head. The carriage can be moved along a guide bar by the driving system including a toothed driving pulley, a cylindrical driven pulley and a timing belt, which runs between the pulleys. The carriage is fixed to the belt. When the carriage moves, it pushes the lever for operating the maintenance mechanism. This applies a high load to the driving pulley. Part of the belt has teeth for meshing with the driving pulley when the carriage moves in the area where the high load is applied to this pulley. Consequently, the driving pulley does not slip on the belt.
