Printer Assembly for UT3000A Monitor
UT3000A Patient Monitor Printer Component, Including Printing Rollers & Cover - Replacement Part
► Brief Description
The UT3000A Patient Monitor Printing Component is a key hardware component designed specifically for medical patient monitoring systems. This component ensures reliable printing of vital signs data, providing clinicians with paper records for patient medical records and reports. It connects directly to the UT3000A Patient Monitor, and its primary function is to convert digital physiological data (such as ECG waveforms, blood pressure readings, and blood oxygen saturation) into paper format.
► Functions
The UT3000A patient monitor mainly includes the following components and functions:
• Main components: Digital thermal printhead array assembly
• Print width (48 mm on 58 mm paper)
• Motor (paper drive) and drive circuitry
• Paper out or recorder door open detector
• Selectable print speed (12.5 mm/s, 25 mm/s) Printhead control is implemented by the motherboard. The microprocessor sends data to the device via a local bus.
► Removing the Printer
1. Push the plastic cover upwards to open the door.
2. Unscrew the two screws.
3. Pull the printer straight out of the monitor and disconnect the connector.
4. The printer is now removed.
► Maintenance and Troubleshooting
As mechanical components, the UT3000A printer assembly may require maintenance during its lifespan. The following are common issues that may arise with this assembly:
● Paper Jam: This is usually caused by worn or misaligned print rollers. Replacing or cleaning the print rollers within this assembly will resolve the issue.
● Paper Feed Failure: If the monitor screen displays an error message indicating that paper cannot be fed, this is usually due to aging rubber on the paper feed rollers.
● Physical Damage: Cracks in the casing/body can prevent the printer from recognizing that the casing is closed, resulting in printing malfunction.
