1. What Is the Samsung CLX-S8640T?
-
The CLX-S8640T is not a standalone printer — it’s actually an optional triple-cassette feeder (paper tray module) designed for the Samsung CLX-8640ND / 8650ND multifunction laser printers.
-
This feeder adds up to 1,560 additional sheets of paper capacity.
-
In the broader system, this means the CLX-8640ND (or 8650) can handle very large print jobs, high paper volume, or large-department usage — making it a key accessory for business environments.
2. System Specs & Features (With the Feeder)
Because the S8640T is a feeder, much of its utility depends on the MFP it’s attached to. Below are relevant specs of the base printer (CLX-8640ND) plus how the feeder enhances performance:

-
Physical Size & Weight (Base MFP): ~550 × 523 × 776 mm, ~70.4 kg.
-
Power Consumption: ~1.6 kW when active per one spec; lower in sleep.
3. Performance & Real-World Use
Capacity & Throughput
-
The triple-cassette feeder dramatically increases the paper capacity, making the system suitable for large jobs or high-volume workflows — e.g., shared print environment, departmental printer, or centralized output hub.
-
With 1,560 extra sheets plus the base capacity, the MFP can run for long print runs without frequent paper refills.
Reliability & Business Productivity
-
The 1 GB memory + 320 GB HDD helps manage large or complex print jobs, spool efficiently, and store job data.
-
The 1 GHz dual-core processor (Chorus4N) ensures the printer can handle multiple simultaneous jobs or heavy-duty tasks without major slowdowns.
-
Automatic duplex allows double-sided printing, reducing paper use and cost.
Scanning & Workflow Integration
-
The built-in ADF (100 sheets) supports efficient scanning of multi-page documents.
-
Scanning to network folders, email, or USB combined with large HDD means it can double as a document archive or digital workflow engine.
-
The optional security features (SSL, IPsec, etc.) help protect sensitive document workflows.
Usability
-
The MFP features a 7-inch color touchscreen, which is useful for interacting with print, scan, and job-box functions.
-
The feeder (S8640T) supports “paper empty / size detect” which helps reduce job interruptions by automating status detection.
4. Strengths & Weaknesses — With the Triple Feeder
Strengths:
-
High paper capacity: The triple feeder provides a total of 2,180 sheets, which significantly boosts productivity.
-
Robust performance: Good memory, HDD, and CPU make it reliable for business-critical print jobs.
-
Flexible media support: Works with a variety of media, including heavy stock or custom-sized sheets.
-
Advanced security: Network security features make it suitable for enterprise environments.
-
Scalable: Because the feeder is optional, you can tailor capacity to your needs (i.e., add it only if you need high volume).
Weaknesses / Trade-offs:
-
Cost: The feeder itself is a significant investment (list price for the S8640T is ~$1,250 per older pricing sheets).
-
Power usage: Operating wattage is high when in use (~1.6 kW per spec).
-
Footprint & weight: With the extra feeder, the physical footprint and weight of the system increase — needs floor or large desk space.
-
Maintenance: More trays mean more potential for paper jams, tray misfeeds, and maintenance.
-
Obsolescence: As an older Samsung MultiXpress model, service or parts may be less common now.
5. Business Use & Deployment Scenarios
Ideal Use Cases:
-
Large Print Workgroups — For departmental printing where many users share a high-capacity MFP.
-
Central Print Room — As a workhorse in a print hub, where large volume, long runs, and varied media are common.
-
Archive / Scan Hub — Use for scanning large batches to HDD or network folders, especially for document-heavy offices.
-
Mixed Media Printing — With its support for heavier media and envelope/cardstock, it can do more than just plain paper.
Less Ideal Situations:
-
If your print volume is very low, the extra capacity might not justify the cost of the feeder.
-
For very small or compact offices: the system (MFP + feeder) may be too big.
-
If color isn’t required: a monochrome MFP might be more cost-efficient.
-
For highly mobile or cloud-native workflows: newer devices might offer better cloud-native integration.
6. Deployment & Procurement Tips
-
Assess Your Volume: Before buying the S8640T, model your monthly paper usage to make sure that 1,560 extra sheets aligns with your needs.
-
Add Feeder Gradually: If you're unsure, you can start with the base MFP and add the feeder later if usage grows.
-
Optimize Tray Setup: Use the feeder for plain paper, the main tray for special media, and MPT for envelopes or custom sizes.
-
Plan Maintenance: More trays mean more maintenance — ensure your support contract or in-house team is ready.
-
Use Duplex: Make duplex printing the default to maximize efficiency & cost savings.
-
Secure Print: Use the HDD-based job storage + security features (if available) to protect confidential jobs.
-
Energy Policy: Implement energy-saving settings to minimize power usage when idle.
7. Final Verdict
The Samsung CLX-S8640T is a powerful accessory for organizations using the CLX-8640ND/8650ND MFP and needing very high paper capacity. It’s not a standalone device — but when combined with the base printer, it helps turn that laser MFP into a high-throughput, enterprise-ready workhorse.
-
✅ Recommended if your office prints large volumes, uses mixed media, and wants to reduce interruptions from refilling paper.
-
⚠ Consider alternatives if your volume is moderate, space is tight, or you don't need more than the base capacity.
