Does the size or quantity of nozzles have any issues with clogging?
The Memjet printhead nozzles are small enough that the human eye is not able to see the impact of single clogged nozzles distributed randomly across a Memjet printhead. Even so, the Memjet components and related ink delivery and maintenance systems have been carefully designed to mitigate clogging and other potential problems that lead to print quality issues. The surface of the Memjet printheads and the silicon nozzle’s structure are designed to be effectively wiped clean by a maintenance system. Each Memjet based device will be delivered with a maintanence system designed to keep nozzles healthy while the device is printing as well as after it has been idle for a period of time. Maintenance system regimes have been designed into Memjet controller chips and can also be adjusted by OEM brands to support a range of printing environments and customer requirements.
