The CMD-V4 (Cash Media Dispenser V4) is the beating heart of Wincor Nixdorf's ProCash ATM series. If you operate ProCash 1500XE, 2050XE, 2100XE, 280, or 285 machines, this module determines your machine's uptime — and your maintenance budget.

After servicing thousands of Wincor ATMs, our engineering team has compiled what matters most: how the CMD-V4 works, what breaks first, and which parts you should keep in stock.

Why CMD-V4 Matters

The CMD-V4 handles every banknote your ATM dispenses. It pulls notes from cassettes, verifies them through sensors, stacks them, and presents them to the customer. One failure here means one machine out of service.

Unlike earlier vacuum-based designs, CMD-V4 uses friction-pick technology with precision roller assemblies. This gives it better multi-currency handling but also creates specific wear points that experienced engineers learn to watch.

CMD-V4 Architecture: 5 Key Subsystems

[Cassette Bank] → [Pick Module] → [Transport Path] → [Stacker] → [Presenter/Shutter]
↑                 ↑                ↑               ↑              ↑
Cash Storage    Friction Rollers   Belt + Sensors   Note Stacking   Customer Access

1. Cash Cassette Bank (FSM Type)

Standard capacity: 1,000–2,200 notes per cassette

Common PN: 01750109646 / 1750109646

Lock type: Mechanical key lock + electronic seal detection

Tip: Cassette wear shows first at the pusher plate spring — weak springs cause misfeeds.

1. Pick Module

Friction-pick mechanism with high-grip rollers

Dual-detection photoelectric sensors prevent double-picks

Pick roller replacement interval: ~500,000 cycles

Key wear part: Pick roller rubber degradation, especially in humid climates

1. Transport Path

Belt-driven with tension sensors at each junction

Optical sensors track note position through 5 detection points

Belt replacement interval: ~1,000,000 cycles or visible cracking

Most common failure: Belt stretching causes timing errors → note jams at diverter gates

1. Stacker Assembly

Bundles notes for presentation

Stacker wheel alignment is critical — 0.5mm misalignment leads to skewed bundle rejection

Clean every 6 months in dusty environments

1. Presenter / Shutter

Motorized shutter with anti-fishing protection

Presenter rollers grip and extend note bundle to customer

Common issue: Shutter motor gear wear after 300,000+ cycles

Top 5 CMD-V4 Replacement Parts (By Failure Frequency)

CMD-V4 Error Codes: Quick Reference

Always clean sensors before replacing them. 70% of sensor errors are dust-related, not component failure.

CMD-V4 vs. Competitors

The CMD-V4 sits in a sweet spot: simpler than NCR's vacuum-based SDD, more refined than older Hyosung CDUs. For operators running mixed fleets, it's often the most cost-effective module to maintain.

Procurement Best Practices

Stock high-wear items — keep at least 2 sets of pick rollers and transport belts per 10 machines.

Cassettes are model-specific — CMD-V4 FSM cassettes work across ProCash 1500XE/2050XE/2100XE/280/285 but not ProCash 4000 or CMD-V2.

Sensors are the money-savers — a $15 sensor replacement beats a $1,500 module swap. Don't skip diagnostics.

Aftermarket is not always equal to OEM — quality varies significantly. Ask your supplier for test reports and warranty terms.

Bundle orders — pick rollers, belts, and sensors ordered together reduce shipping cost per part by 60–70%.

The Bottom Line

The CMD-V4 is a workhorse — reliable when maintained, expensive when neglected. Know your wear intervals, stock the right parts, and you'll keep your ProCash fleet running at 98%+ uptime.

FAQ

Q1. What does CMD-V4 stand for?

Cash Media Dispenser V4. It is the dispenser module of Wincor Nixdorf's ProCash ATM series — it pulls notes from cassettes, verifies them through sensors, stacks them, and presents them to the customer.

Q2. Which ProCash models use the CMD-V4?

ProCash 1500XE, 2050XE, 2100XE, 280, and 285. CMD-V4 FSM cassettes work across all of these models, but not ProCash 4000 or CMD-V2.

Q3. What is the CMD-V4 cassette part number and capacity?

The FSM-type cash cassette holds 1,000–2,200 notes per cassette; common PN is 01750109646 / 1750109646. It uses a mechanical key lock plus electronic seal detection, and cassette wear shows first at the pusher plate spring — weak springs cause misfeeds.

Q4. Does the CMD-V4 use vacuum or friction pick?

Friction. Unlike earlier vacuum-based designs, the CMD-V4 uses friction-pick technology with precision roller assemblies, which gives it better multi-currency handling but creates specific wear points. Dual-detection photoelectric sensors prevent double-picks.

Q5. What does error 3.030.01 mean on a CMD-V4?

Pick failure. The most likely causes are worn pick rollers or a weak cassette spring.

Q6. What causes a CMD-V4 transport jam (3.035.01)?

Belt stretching or diverter misalignment. The transport path is belt-driven with tension sensors at each junction, and stretching belts cause timing errors that jam notes at the diverter gates.

Q7. How often do CMD-V4 pick rollers and transport belts need replacing?

Pick rollers at roughly 500,000 cycles; transport belts at roughly 1,000,000 cycles or at visible cracking. The presenter shutter motor gear wears after 300,000+ cycles.

Q8. Does a CMD-V4 sensor fault mean the sensor is dead?

No — clean it first. About 70% of sensor errors are dust-related rather than component failure, and a $15 sensor replacement beats a $1,500 module swap, so diagnostics should not be skipped.
