Maintenance system having modular sled
View Patent ↗A maintenance system for a printhead, the system having a sled slidably arranged with respect to the printhead a media platen module supported by the sled a capper module supported by the sled a wiper module supported by the sled; and a selection mechanism for selectively sliding the sled to align one of the platen, capper and wiper modules with the printhead, and for moving the aligned module to a position in proximity of the printhead.
1. A maintenance system for a printhead, the system comprising:
a sled slidably arranged with respect to the printhead;
a plurality of maintenance modules supported by the sled;
a selection mechanism for selectively sliding the sled to align one of the maintenance modules with the printhead; and
a lift mechanism comprising:
a lift arm for engaging with a selected module only when the selected module is aligned with the printhead; and
a motor for causing the lift arm to lift and lower the selected module, the lifted position being in proximity of the printhead,
wherein the lift arm is engageable with each of the modules.
2. A maintenance system according to claim 1 , wherein the lift mechanism further comprises a cam engaged with the motor, the cam arranged to be engaged and disengaged with the lift arm to cause said lifting and lowering of the engaged module.
3. A maintenance system according to claim 2 , wherein the lift mechanism further comprises a spring attached to the lift arm for biasing the lift arm to the lowered position.
4. A maintenance system according to claim 1 , wherein the plurality of maintenance modules comprises: a media platen module; a capper module; and a wiper module.
5. A printer comprising the maintenance system according to claim 1 .
