Wincor Nixdorf / Diebold Nixdorf POS Parts: Identify Your BEETLE and TH-Series Printer and Order the Right Part
A sourcing guide to Wincor Nixdorf (now Diebold Nixdorf) POS hardware — the BEETLE terminal ecosystem, the TH230/TH230+/TH320 receipt printers, reading the 1750 part-number scheme, and matching printheads, cutters and the right 24V supply.
The fast answer
Wincor Nixdorf — now part of Diebold Nixdorf — BEETLE terminals and TH-series receipt printers fill checkout lanes across European and global retail. Sourcing parts for them is easy once you know the rule: everything is keyed to the 1750 part-number scheme. Capture the model name and the 1750 number and the rest follows:
| Step | What to capture | |
|---|---|---|
| 1. Read the model name | e.g. TH230 / TH230+ / TH320, or a BEETLE terminal model | — |
| 2. Read the 1750 part number | e.g. 01750119382 — on the device label | — |
| 3. Note the voltage | TH printers are typically 24V (from BEETLE or external PSU) | — |
| 4. Cross-reference & order | Match the 1750 OEM number to a tested equivalent | — |
The BEETLE POS ecosystem
BEETLE is Wincor’s modular POS terminal family — the system the TH-series printers and other peripherals plug into. Because it’s modular, a checkout is assembled from a terminal plus printer, display, scanner and so on, often powered and connected through the BEETLE itself. That matters for sourcing because the printer frequently draws its 24V from the terminal rather than its own brick.
| Component | Role in a BEETLE checkout | |
|---|---|---|
| BEETLE terminal | The modular POS host; often powers the printer at 24V | — |
| TH-series printer | Receipt (and on TH320, slip) printing | — |
| Operator / customer display | Cashier and shopper screens | — |
| Scanner / scale / MSR | Peripherals on the same modular system | — |
The TH-series receipt printers
The TH-series receipt printers are the parts most people are here for. The key split is receipt-only vs hybrid:
| TH230 / TH230+ | TH320 | |
|---|---|---|
| Type | Thermal receipt (2-colour capable) | Hybrid: thermal receipt + impact slip |
| Receipt speed | Up to ~220 mm/s | Thermal receipt station |
| Slip / cheque printing | No | Yes (impact slip station) |
| Cutter | 90 mm receipt cutter | 90 mm receipt cutter |
| Power | 24V (BEETLE or external PSU) | 24V (BEETLE or external PSU) |
| Best for | Receipts only | Receipts + slip/cheque at one station |
Reading the Wincor 1750 part-number scheme
Everything hinges on the Wincor part number. It’s a 1750-series code printed on the device label — read it in full:
The label is usually on the base or rear of the printer or terminal. Capture the complete 1750 number plus the model name — together they let a supplier match the exact part across both the Wincor and Diebold Nixdorf catalogues.
Wear parts (and the 24V power detail)
These are the parts that actually wear on a TH-series printer. Replacing the right one beats replacing the printer:
| Part | Symptom / note | |
|---|---|---|
| Thermal printhead | Faint or missing dots; cross-fits TH230/+/320/420 (verify by 1750) | — |
| Receipt cutter (90 mm) | Jams or won't cut cleanly | — |
| Platen roller | Feed problems and smudging | — |
| Slip-station parts (TH320) | Slip print/feed faults on the hybrid model | — |
| 24V power supply | Dead printer — match 24V and connector exactly | — |
Cross-referencing and ordering
Put it together into a clean order:
- 1
Capture the identifiers
Note the model name (e.g. TH230) and the full 1750 part number from the label, plus the voltage (typically 24V). - 2
Decide receipt-only vs hybrid
Confirm whether you need a receipt-only part (TH230/TH230+) or a hybrid TH320 slip station — they differ beyond the shared thermal head. - 3
Cross-reference the 1750 number
Match the Wincor/Diebold Nixdorf OEM 1750 number to a genuine or quality-tested equivalent — for the printhead, confirm TH-series fitment by that number. - 4
Verify before shipping
Send a photo of the device label (model + 1750 number) to your supplier so they can confirm the part — including voltage and interface — before it ships.
