Abstract: Example embodiments of wiping are shown and described in which a print head is wiped along a non-linear path.

Abstract: A pen having a printhead and a chamber for holding ink; a sensor for monitoring changes in the amount of ink in the chamber; and a pump for selectively drawing ink into or expelling ink from the chamber.

Abstract: A system for receiving and recycling ink comprises a print cartridge having a printhead, and an ink supply reservoir fluidly connected to the print cartridge and a seal member coupled to the ink supply reservoir. The seal member defines a fluid path into the reservoir and the print cartridge engages the seal member so that ink spit from the printhead flows through the fluid path into the reservoir.

Abstract: A printhead servicing mechanism comprises a printhead capping device that moves between a storage position and a printhead capping position, and a crank arm assembly that moves the printhead capping device between the storage and capping positions.

Abstract: A cleaning solvent for use with an ink-jet printer, in particular an ink-jet printer having a printhead servicing system, wherein the cleaning solvent comprises glycerin and a polyhydric alcohol, such as 1,3-propanediol. The cleaning solvent is optimized for efficient printhead cleaning regardless of the printer operating environment. A method for cleaning an ink-jet printhead comprises transferring an amount of a cleaning solvent comprising glycerin and a polyhydric alcohol to a printhead surface and cleaning the printhead.

Abstract: An apparatus and method are disclosed herein for capping one or more printheads in a printing device. Further characteristics and features of the present invention are additionally disclosed herein, as are exemplary alternative embodiments. This abstract is not to be used in the interpretation of any of the claims.
