Latest Patents

Barton’s patent, “Spill Resistant Spittoon for Printer Service Stations,” describes a waste-ink reservoir used when servicing an inkjet printhead. Its bottom and walls form the reservoir, while an inwardly extending lip on at least one wall helps retain ink when the spittoon is moved or tilted. This design aims to minimize spills during printer maintenance.

His patent, “Method and Apparatus to Oppose a Short Circuit Failure Mechanism in a Printer Drive Circuit,” presents a protection method for printer address lines connected to multiple printheads. Resistors placed in series between the head driver and each connected printhead help isolate a short circuit. This arrangement can protect the driver and allow it to continue controlling address lines for printheads that have not failed, helping users identify and replace a malfunctioning printhead.
