Abstract
An example printing fluid apparatus, for a printing system, comprises a printing fluid reservoir to store printing fluid for use in a print job and a printing fluid channel to route printing fluid from the reservoir to the reservoir and to route printing fluid from a printing station of the printing system to the reservoir. The fluid channel comprises a port to introduce printing fluid from a printing fluid cartridge into the fluid channel such that the introduced printing fluid from the printing fluid cartridge at least partially mixes with printing fluid in the fluid channel.
Claims15
A printing fluid apparatus for a printing system, the printing fluid apparatus comprising:
- a printing fluid reservoir to store printing fluid for use in a print job;
- a printing fluid channel to route printing fluid from the reservoir to the reservoir and to route printing fluid from a printing station of the printing system to the reservoir, wherein the fluid channel comprises a port to introduce printing fluid from a printing fluid cartridge into the fluid channel such that the introduced printing fluid from the printing fluid cartridge at least partially mixes with printing fluid in the fluid channel before being introduced back to the reservoir.
A printing fluid circulation method comprising:
- receiving printing fluid from a printing fluid reservoir or from a printing station in a return conduit;
- routing printing fluid in the return conduit to the reservoir;
- injecting printing fluid from a printing fluid cartridge into the return conduit such that the injected printing fluid at least partially mixes with the printing fluid in the return conduit before being introduced back to the printing fluid reservoir.
A printing fluid circuit comprising:
- a fluid tank to hold printing fluid;
- a return conduit to introduce printing fluid into the fluid tank;
- a circulation conduit fluidly connected to the fluid tank and the return conduit to direct fluid from the fluid tank to the return conduit;
- a printing station conduit fluidly connected to the return conduit to direct printing fluid form a printing station to the return conduit;
- and
- a printing fluid injection conduit fluidly connected to the return conduit to inject printing fluid from a printing fluid cartridge into the return conduit such that the injected printing fluid at least partially mixes with the printing fluid in the return conduit before being introduced back to the fluid tank.
