Optimise your operations with proper maintenance of barcode scanners and label printers
At Delfi Technologies, we understand the importance of ensuring that your solutions always perform optimally. Since 1988, we have specialised in delivering innovative barcode technologies and data capture solutions that help our customers optimise their business. A crucial part of ensuring continuous efficiency and avoiding costly breakdowns is regular and proper maintenance of barcode scanners and label printers. Our expertise spans a wide range of hardware, including handheld terminals, PDAs, barcode scanners and label printers, and we combine software and hardware to create tailored solutions that meet specific needs within retail, warehouse management, industry and the healthcare sector.
This guide has been prepared to provide you with the necessary knowledge and best practices to extend the lifespan of your equipment and ensure smooth operations. By investing time in preventive maintenance, you can minimise the risk of operational disruptions, reduce repair costs and maintain high productivity.
Why is maintenance of barcode scanners and label printers essential?
Imagine a busy warehouse or shop where the barcode scanners suddenly stop working, or the label printer fails in the middle of a large shipment. The consequences can be devastating: delayed deliveries, dissatisfied customers, lost revenue and frustrated staff. Whether you work in logistics, retail or the healthcare sector, reliable equipment is fundamental to efficient operations.
Regular maintenance is your best insurance against unforeseen breakdowns. It is not only about repairing after the damage has occurred, but even more about prevention. By taking good care of your equipment, you ensure not only a longer lifespan, but also more stable and accurate performance.
At Delfi Technologies, we have seen how well-maintained equipment contributes to higher employee satisfaction and better-optimised workflows. We offer a range of solutions for warehouse management and retail that are designed to work seamlessly with our equipment, and proper maintenance is the key to maximising these solutions.
Maintenance of barcode scanners: An essential guide
Barcode scanners are often subjected to intensive use in demanding environments. Dust, dirt, daily wear and tear, and even accidental knocks can affect their performance. A proactive approach to maintenance is therefore essential.
Regular cleaning of barcode scanners
The most fundamental part of good maintenance is regular cleaning. The scanner’s “eye” – the scanning window – must be crystal clear to read barcodes accurately. Over time, dust, smudges and fingerprints will inevitably accumulate here.
- Disconnect the power: Always ensure the equipment is switched off and disconnected from the power source before cleaning.
- Use a soft, lint-free cloth: Gently wipe the scanner’s window and housing. Avoid rough materials that can scratch the surface.
- Mild cleaning agent: For more stubborn stains, a slightly damp cloth with a mild, non-abrasive cleaning solution may be used. Avoid harsh chemicals such as acetone, petrol or industrial cleaners, as these can damage plastic and optics. Isopropyl alcohol (IPA) is often a safe choice, but always test on an inconspicuous area first.
- Disinfecting barcode scanners: In environments such as healthcare or food production, disinfection is essential. Use disinfectant wipes or sprays approved for electronics and follow the manufacturer’s instructions. This is particularly important for handheld terminals and scanners that change hands frequently.
- Cleaning buttons and crevices: Use a cleaning brush or compressed air to remove dust and dirt from buttons and small crevices.
We recommend daily wiping for scanners in high-use environments and a weekly, more thorough cleaning.
General tips to extend service life
- Avoid knocks and drops: Although many of our scanners are built to withstand drops, repeated impacts over time will shorten their service life. Store scanners in their charging cradles or dedicated locations when not in use.
- Proper storage: Store scanners in a clean, dry environment away from extreme temperatures and direct sunlight.
- Check cables and connections: Damaged cables are a common cause of connection issues. Inspect regularly for signs of wear or kinks.
- Firmware updates: Keep your scanner’s firmware up to date. Manufacturers often release updates that improve performance, fix bugs and add new features. You can find information about updates for Delfi products on our website.
- Battery care: For wireless scanners, battery care is critical. Use only original batteries and chargers. Avoid fully discharging the batteries or constantly overcharging them.
Maintenance of label printers: For perfect print results
Label printers are the backbone of many operations, from shipping to in-store labelling. The quality of your labels depends directly on the condition of the printer. Proper maintenance of barcode scanners and label printers is equally important.
Key points for maintaining label printers
- Cleaning the printhead: This is probably the most important maintenance task. A dirty printhead can cause unclear, streaky or incomplete prints. Use special cleaning wipes or pens intended for thermal printheads. Clean the printhead after each replaced roll of labels or ribbon, or when you notice reduced print quality. Do not touch the printhead with your fingers.
- Cleaning rollers: The feed roller (platen roller) moves the labels through the printer. Build-up of adhesive, paper dust and dirt on the roller can lead to label jams or poor print quality. Clean the roller with a lint-free cloth moistened with IPA.
- Remove dust and dirt: Use compressed air or a soft brush to remove paper dust and other particles from inside the printer, especially around sensors and moving parts.
- Use the right consumables: Always use high-quality labels and ribbons recommended for your printer model. Cheap consumables can damage the printhead and reduce print quality. At Delfi, we offer a wide range of certified labels and ribbons that ensure optimal performance and extended service life for your printer.
- Software and firmware updates: As with barcode scanners, it is important to keep the printer’s software and firmware up to date. This ensures compatibility, improved performance and access to new features.
- Correct placement and environment: Place the printer on a stable, level surface away from direct sunlight, heat sources and moisture. Ensure adequate ventilation.

How do I best clean my barcode scanner window?
Use a soft, lint-free cloth, optionally slightly moistened with an isopropyl alcohol-based solution. Wipe gently to avoid scratches and ensure a clear reading surface. Avoid harsh chemicals.
How often should I clean the printhead on my label printer?
We recommend cleaning the printhead after each replaced roll of labels or ribbon, or as soon as you notice reduced print quality (e.g., streaks on the labels). This is essential for optimal maintenance of barcode scanners and label printers.
Can I use standard cleaning products on my equipment?
No, it is not recommended. Many standard cleaning products contain chemicals that can damage plastic parts, optics or electronic components. Always use cleaning agents specifically designed for electronics, such as isopropyl alcohol (IPA).
