💡 Key Functions
1. Pressure Stabilization: During the inkjet printing process, the operation of the ink pump generates periodic pulsations; the damper (buffer) absorbs these fluctuations to provide consistent ink pressure.
2. Maintaining Print Quality: Stable pressure ensures precision in ink droplet formation and charging, preventing issues such as character distortion, broken lines, or unclear printing.
3. Protecting Ink System Components: By reducing the physical impact of pulsations on tubing, filters, and valves, it extends the service life of the entire ink delivery system.

FAQ
Q1: What alarms or symptoms occur if the buffer in a VJ 1000 series printer fails?
A：When the internal diaphragm of the buffer ages or becomes clogged with ink, preventing it from effectively absorbing pump pulsations, the following issues typically arise:
• Alarms: The screen most frequently displays "Pump RPM Near Maximum" or "Ink Pressure Fault." This occurs because the system forces the pump to run at an excessive speed to maintain stable pressure.
• Printing Irregularities: The ink stream at the printhead may fluctuate, and ink drop charging may become unstable. This results in printed characters that appear shaky (vertically) or have inconsistent widths; it can even frequently trigger an "EHT Trip" (High Voltage fault).
 
Q2: Where is this buffer located within the machine?
A：It is located inside the unit, next to the "Ink Core" (the core fluid system component).
• After the gear pump draws the ink, the ink flows directly into this buffer. The buffer smooths out the pulsations before the ink continues on to the main filter and eventually to the printhead.
 
Q3: What should be kept in mind when replacing part number VB-CPC000100031?
A：• Pressure Relief and Shutdown: Before replacement, perform a nozzle flush and shut down the machine completely. Ensure the fluid system is fully depressurized to prevent ink from spraying out during disassembly.
• O-Rings: The buffer connection points are equipped with solvent-resistant O-rings. When installing the new part, ensure the O-ring is correctly positioned and undamaged; otherwise, it could easily lead to ink leaks or the intake of air into the system.
• Air Purging: Upon restarting the machine after replacement, allow it to run through a "Clean Start" or "Ink On" cycle for several minutes. This ensures that any air trapped in the fluid system is purged through the sub-tank.
 
Q4: How should one choose between original manufacturer (OEM) parts and compatible (third-party) parts?
A：• Original Equipment Manufacturer (OEM) parts: Offer the most consistent quality, excellent solvent resistance, and superior pressure tolerance, though they come at a higher price point.
• Compatible parts: There are many third-party compatible dampers on the market specifically designed for the VJ 1000 series, offering a strong price-to-performance ratio. When purchasing compatible parts, ensure the supplier uses imported, corrosion-resistant diaphragms; the internal diaphragms in cheaper, low-quality alternatives can easily dissolve when exposed to MEK (methyl ethyl ketone)-based inks, leading to secondary clogs.
Q5: Can you source specific coding/marking machine parts that are not listed on your website?
A: Yes, we can. Given the vast range of available parts, not all models are featured on our website. Please feel free to send us an inquiry at any time; we can also provide our latest and most comprehensive product catalog. Once we receive your request, a dedicated representative will get in touch with you promptly to assist with a price quote.
