A practical replacement plan for obsolete, unreliable or unsuitable coders, covering mounting, sensors, data, trials, changeover and handover.
Start by recording the existing coding duty, line interfaces and accepted print result before choosing a new printer. A successful replacement preserves the useful mechanical position, product handling, data ownership and inspection method, while correcting the reason the old system is no longer suitable. The replacement model should be proven with the real pack and message before the old coder is removed.
Record technology, model, printhead orientation, message, print height, pack material, speed range, product pitch, code position and current defects.
Document power, sensor, encoder, mounting, PLC I/O, network connection, job selection, vision or scanner input, reject output and line-stop logic.
Retain approved code samples and criteria for content, position, contrast, drying, adhesion, scan performance, changeover and fault recovery.
The decision should consider production risk and complete ownership, not the age of the printer alone.
| Condition | Repair may remain appropriate when | Replacement deserves assessment when |
|---|---|---|
| Print quality | The approved ink and pack are unchanged and a diagnosed service item can restore the accepted result. | The required code, resolution, contrast or position is outside the practical capability of the installed system. |
| Reliability | Faults are isolated, parts and competent support remain available, and recovery is predictable. | Unplanned stops recur, support or parts are uncertain, or failure risk is no longer acceptable to production. |
| Data and traceability | The current controller can receive and protect the required data with suitable permissions and checks. | New ERP/MES, serialisation, 2D-code, vision or audit requirements cannot be supported safely. |
| Line changes | The product path, speed and code position remain within the installed printer's approved range. | New packs, higher output, different surfaces or a moved coding point require different sensing, mounting or technology. |
| Ownership cost | Consumables, service and operator intervention remain proportionate to accepted production. | Consumable waste, cleaning, downtime and specialist intervention make the current route uneconomic or difficult to support. |
A like-for-like printer is not always the lowest-risk route. Compare the production task against the current Lancing model references and the existing conveyor condition.
Where the conveyor already presents a stable flat code panel, a bolt-on thermal inkjet arrangement such as the LU-IIP600-B reference route can add a controller, printhead, product sensor, encoder and adjustable mount without replacing the main line.
Where no suitable conveyor exists, an integrated coding conveyor such as the LU-DC127 reference route can provide controlled transport, sensing and printhead mounting as one station.
For faster moving, curved or variably presented products, assess a CIJ route such as the LU-TIP15 reference model. Confirm ink, make-up fluid, ventilation, start/stop routine and print distance against the site.
If the requirement is occasional rework or small batches without a fixed line, the LU-DC1S handheld route may be more practical. A jig or guide may still be required for repeatable position.
Where the new message is taller or needs more than one print position, review the LU-IIP550 configurable inline route and prove the head count, message, speed and data path.
Moving flexible film may suit thermal-transfer overprinting, detailed logistics labels may suit print-and-apply, and permanent high-contrast marking may justify laser assessment. Choose from the pack, production method and acceptance criteria rather than retaining inkjet by default.
| Area | Record before removal | Confirm for the replacement |
|---|---|---|
| Mechanical | Mounting dimensions, working height, product guides, vibration, access, guarding and cable routes. | New bracket, adjustment range, protection, cleaning access and safe changeover. |
| Product detection | Sensor type, position, trigger edge, delay and missed-product history. | Pack colour/shape compatibility, trigger repeatability and fault indication. |
| Speed reference | Fixed speed, encoder type, wheel position, pulses or existing speed signal. | Permitted speed range, acceleration, start/stop behaviour and slip risk. |
| Data | Message source, approved templates, date logic, users, network and backup method. | File migration, permissions, interface protocol, clock source and communication-loss response. |
| Quality control | First-off sample, inspection frequency, scanner or vision settings and reject method. | Acceptance criteria, challenge tests, reject confirmation and record retention. |
| Utilities and environment | Power, air if used, ventilation, temperature, humidity, dust, washdown and hazardous-area information. | Exact model limits, isolation, enclosure, fluid controls and site risk assessment. |
Photograph the current installation, export approved messages, record settings and retain accepted print samples before disconnection.
Use production packs, the real message and the intended ink. Check position, contrast, drying, adhesion and machine-readable codes where required.
Prove sensing, speed compensation, job selection, data transfer, alarms, line stop, vision and reject response rather than testing print alone.
Run the smallest and largest formats, speed changes, short stops, power recovery and communication loss using the approved operating method.
Train operators, quality and maintenance personnel, then retain drawings, settings, backups, consumable references and escalation contacts.
Remove fluids, cartridges, batteries and electrical equipment through the correct site and supplier routes. Keep required production and maintenance records.
Maximum printer capability may not apply to the required font, rows, resolution, substrate, print gap or product rate. Quote the exact message and line conditions.
Voltage, output type, pulse rate, connector, software and mounting can differ. Document the current signals and prove the complete replacement interface.
Guides, belts, pack contact, case packing or immediate stacking can smear a code that appeared acceptable at the printhead. Test the full downstream route.
Use the replacement as a controlled opportunity to confirm date logic, variable fields, permissions and approved templates rather than copying every legacy file.
Plan the installation window, production stock, temporary coding route and reversal criteria before the line is unavailable.
Confirm operator training, consumables, spares, backups, service boundaries, warranty, documentation and support contacts in the written quotation.
Possibly, but the bracket must be checked for dimensions, rigidity, adjustment, guarding, print distance and safe access. Reusing an unsuitable mount can undermine the performance of the new printer.
Some files can be recreated or imported, but formats and variable-data functions differ between controllers. Validate every transferred template, date rule, font, barcode and user permission before release.
Yes. A new ink, cartridge, printhead or mounting arrangement can change adhesion, dry time, contrast and code position even when the message looks similar.
Installation usually requires a controlled window for mechanical, electrical and validation work. The duration depends on the existing interfaces and whether mounting and off-line testing can be prepared in advance.
Send photographs and video of the installed coder and product path, model and serial numbers, actual code, pack samples, speed range, mounting measurements, signal details, fault history and required completion window.
Not automatically. Reassess the current pack, data, quality and ownership requirement. A changed surface, code or line may make CIJ, TIJ, large-character, handheld or a non-inkjet alternative more suitable.
Send the existing installation evidence and required code so Lancing can compare repair, retrofit and replacement routes.
