Negative pressure management
Manage ink supply negative-pressure status using target values and detection feedback.
FHES / INK SUPPLY PCS
Use MCU digital control to manage negative pressure, temperature, ink supply and FWS fault alerts centrally; confirm accuracy indicators against the specific model and actual-machine testing.
The image shows the PCS MCU control board. Validate specifications, function coverage and delivery configuration against the model, ink and physical system.
01 / INTEGRATED CONTROL
PCS brings ink supply, negative pressure and temperature control into unified digital management, reducing the integration complexity of separate controls.
Manage ink supply negative-pressure status using target values and detection feedback.
Multi-stage temperature control works with ink tank agitation and secondary-cartridge recirculation to reduce supply-side sedimentation risk.
Convert monitored exceptions into codes and inspection guidance to help maintenance personnel locate problems.
02 / PERFORMANCE TARGETS
The brochure provides two target performance indicators; measurement points, statistical windows and acceptance methods still need to be defined in the specific model's technical specifications.
Feedback target for the pressure-change detection chain.
The objective is to keep negative-pressure deviation within this range during operation.
These are development targets rather than accepted performance. Verify ink, temperature, measurement points, stabilization time and sampling through physical tests.
03 / INK PATH + MACHINE
PCS covers management of main-tank ink level, dual-printhead-module ink supply, overflow prevention, positive-pressure cleaning and enclosure heat dissipation.
PCS recirculation acts on the supply side of the ink tank and cartridge; it is not equivalent to CCS internal printhead recirculation. Monitoring points, interlock actions and alarm codes depend on the delivered configuration.
04 / SOFTWARE COORDINATION
The supporting software can show settings, actual feedback, alarms and operating logs together, and provide maintenance entry points according to permissions.

The software interface in the brochure is illustrative; displayed items, operating permissions, firmware version and available functions vary with the PCS delivery configuration.

Use operating records to verify negative pressure, temperature control, alarm response and recovery procedures.
APPLICATION TEST / FHES
Provide the ink, printhead, target negative pressure, temperature-control and alarm requirements to help confirm PCS configuration and actual-machine acceptance methods.
