Abstract
An apparatus for use in servicing a printer's printhead is provided which includes an elongate lever pivotally coupled with the printer's chassis so as to accommodate pivoting movement of the lever between a free orientation and a printhead-servicing orientation. A servicing member such as a wiper is mounted on the lever, the servicing member selectively being brought into operative association with the printhead by pivotal movement of the lever into the printhead-servicing orientation. Lever pivoting is controlled via cammed engagement between the lever and a printer carriage.
Claims12
An apparatus for use in servicing a printer with a printhead, said apparatus comprising:
- a carriage mounted for movement relative to a chassis of the printer, said carriage including a cam surface having a ramp region;
- and
- a lever pivotally coupled with the chassis, said lever mounting a printhead-servicing member and including a follower configured to traverse the cam surface of the carriage, said carriage selectively engaging said lever to pivot said lever between a free orientation and a printhead-servicing orientation.
An apparatus for use in servicing a printer with a printhead, said apparatus comprising:
- a lever pivotally coupled with a chassis of the printer, said lever mounting a wiper;
- and
- a carriage mounted for movement relative to the chassis, said carriage selectively engaging said lever to pivot the lever between a free orientation and a printhead-servicing orientation;
- said wiper being mounted such that movement of said lever into said printhead-servicing orientation places said wiper into a predefined wiping position relative to the printhead.
An apparatus for use in servicing a printer with a printhead, said apparatus comprising:
- a carriage mounted for horizontally reciprocal movement relative to the printer's chassis, said carriage including a cam surface having a ramp region;
- and
- an elongate seesaw member mounted for pivotal rotation relative to the printer's chassis, said seesaw member having first and second end regions with said first end region mounting a wiper and said second end region including a follower configured for traverse of the cam surface upon carriage movement, traverse of said cam surface by said follower directing pivot of said seesaw member between a free orientation wherein said wiper is spaced from the printer's printhead and a printhead-servicing orientation wherein said wiper engages the printer's printhead to effect service thereof.
