Comen CM1200B ECG Print Head SHEC CH216-8157 1212 06130038B ECG Spare Parts Used-Good Parts
■ Product Describe
The Comen CM1200B ECG printhead is a brand-new, original, core printing component for the Comen CM1200B ECG machine, specifically designed for its thermal printing system. It accurately prints ECG waveforms and parameter data onto thermal paper, rapidly heating the thermal paper coating to achieve clear images. This crucial component ensures the clarity and integrity of ECG reports, directly impacting the interpretation of ECG waveform details in clinical diagnosis.
This printhead is specifically designed for the Comen CM1200B ECG machine, a multi-lead simultaneous ECG device widely used for cardiac function testing in outpatient clinics, emergency departments, and wards. It offers multiple features, including support for 12-lead simultaneous acquisition and printing, automatic analysis, and support for multiple print formats.
■ Product features
1. High-Definition Waveform Printing
Using a high-density dot matrix, it accurately reproduces subtle changes in ECG waveforms, with a line width error of ≤0.1mm, ensuring clear waveform edges and providing accurate diagnostic support for doctors.
2. High-Speed Printing
Printing speeds are adjustable to three settings: 25mm/s, 50mm/s, and 100mm/s. At 100mm/s, a 30cm report can be printed continuously in just 3 seconds, enabling rapid completion of multi-lead ECG output and reducing patient wait times.
3. Wide-Format Printing
Supporting thermal paper up to 210mm wide, it can print 12-lead synchronized ECG waveforms simultaneously. Precise paper feed control ensures waveform alignment error of ≤0.5mm across each lead, preventing misalignment that can affect waveform comparison and analysis.
4. Stable Heating Control
Equipped with multiple independent heating points, each with a temperature control accuracy of ±2°C, the device can adjust the heating intensity based on waveform grayscale requirements, creating a gradient effect that highlights unusual waveform features.

■ FAQ
Q1: The print head is partially blurry. What could be the cause?
A1: It could be dust or paper residue on the print head surface. We recommend wiping it with a special cleaning swab dipped in alcohol. If the problem persists after cleaning, it could be damage to the heating element, requiring a print head replacement.
Q2: Can this print head be used with non-genuine thermal paper?
A2: We do not recommend this. Non-genuine thermal paper may reduce print clarity due to differences in coating formulas and contaminate the print head with residual colloid, shortening its lifespan. We recommend using genuine thermal paper recommended by Comen.
Q3: How do I determine if a print head has reached the end of its lifespan and needs to be replaced?
A3: If overall print clarity is significantly reduced (grayscale value is less than 50% of the initial value), large areas of missing prints persist after repeated cleanings, or the cumulative print length exceeds 30,000 meters, we recommend replacing the print head.
