How to Reduce Production Downtime with the Right Coding Machine
In the manufacturing world, production downtime is one of the most costly problems. When the production line stops, companies not only lose time, but also risk delivery delays, increased operational costs, raw material waste, and decreased customer satisfaction. One common cause of downtime on production lines is problems in the product coding and marking process.
Coding machines have an important role in printing information such as production date, expiry date, batch number, lot code, barcode, QR code, and traceability data. If the coding machine has problems, products can be held back because they are not allowed to leave without the correct code. Therefore, choosing the right coding machine becomes an important step to maintain smooth production.
Why Can Coding Machines Cause Downtime?
Coding machines work directly on the production line, usually following the speed of the conveyor or packaging machine. When this machine experiences problems, the entire production flow can be affected. Small problems such as blurry print results, clogged ink, ribbon running out, sensors not reading products, or incorrect codes can make operators temporarily stop the machine.
Some common problems with coding machines that can cause downtime include:
- Print results are unclear or broken
- Ink dries or nozzle becomes clogged
- Ribbon often breaks on TTO machines
- Printer is not synchronized with the conveyor
- Product sensor is inaccurate
- Date or batch number input errors
- Machine is difficult to calibrate
- Spare parts are not available when needed
- Technicians are slow to handle damage
If these problems occur frequently, companies will lose a lot of productive time. Even a few minutes of downtime can have a major impact if production runs in high volume.
Impact of Downtime on Production
Downtime does not only mean the machine stops. In practice, this problem can create a chain effect on many operational aspects. Products that have not been printed with codes must be separated, rechecked, or even reworked. Operators must stop the process, technicians need to perform checks, and the production schedule can be disrupted.
Some impacts of production downtime include:
- Daily output targets are not achieved
- Overtime costs increase
- Packaging materials are wasted
- Risk of delivery delays
- Product quality becomes inconsistent
- Operator productivity decreases
- Main machines also stop
- Financial losses increase
- Customer trust decreases
Therefore, coding machines should not be considered merely as additional devices. These machines are an important part of the production system that must be selected, maintained, and supported with the right technical service.
Choose a Coding Machine According to Packaging Type
The first step to reducing downtime is choosing a coding machine that matches the product type and packaging material. Each coding printer technology has different characteristics. If the selected machine is not suitable, production disruptions will occur more frequently.
Several commonly used coding machine technologies include:
- Continuous Inkjet Printer / CIJ
Suitable for fast production lines and various packaging forms, such as bottles, cans, pipes, plastic, glass, and irregular packaging. - Thermal Inkjet Printer / TIJ
Suitable for sharp print results on cartons, labels, and several types of porous and non-porous packaging with certain inks. - Thermal Transfer Overprinter / TTO
Suitable for flexible packaging such as sachets, pouches, plastic film, and snack food packaging. - Laser Marking Printer
Suitable for permanent marking results without ink, especially on certain materials such as cartons, special plastics, bottles, or labels. - Print and Apply Labeling System
Suitable for automatic labeling processes on cartons, boxes, pallets, or products that require labels containing complete information.
By choosing the right technology, the risk of failed print results, ink not adhering, codes easily smudging, or machines stopping frequently can be reduced.
Pay Attention to Production Line Speed
Every production line has a different speed. Some machines run slowly with small volume, while others are high-speed production lines that require coding printers with fast and stable response. Coding machines that cannot keep up with production speed will cause print results to shift, become unreadable, or be missed.
Before choosing a coding machine, companies need to pay attention to:
- Conveyor speed
- Number of products per minute
- Distance between products
- Print area size
- Print position on packaging
- One-sided or multi-sided printing needs
- Integration with packaging machines
The right coding machine must be able to work according to the production rhythm without disrupting the workflow. If the machine capacity is too low, downtime will occur more easily because the machine is forced to work beyond its optimal limit.
Use a System That Is Easy to Operate
Operator error can also cause downtime. For example, entering the wrong expiry date, selecting the wrong print format, forgetting to change the batch number, or incorrectly setting the sensor. To reduce this risk, choose a coding machine with an easy-to-use control system.
Features that help reduce operator errors include:
- Clear screen display
- Simple setting menu
- Code template storage
- Automatic date setting
- Password system to prevent unauthorized changes
- Alarm if ink, ribbon, or consumables are almost empty
- Easy-to-understand error guide
The easier the machine is to use, the lower the possibility of input or setting errors that can stop production.
Ensure Spare Part and Consumable Availability
Coding machines require consumables such as ink, solvent, cartridges, ribbon, filters, or other supporting components. If consumables run out or spare parts are not available, production can stop longer than it should.
To reduce downtime, companies need to ensure:
- Ink or ribbon is always available
- Important spare parts are ready stock
- Consumable replacement schedules are monitored
- Operators know the signs when consumables are almost empty
- Vendor has adequate stock support
Spare part availability is an important factor, especially for factories with busy production schedules. A good machine can still cause downtime if consumable and spare part support is difficult to obtain.
Perform Preventive Maintenance
Routine maintenance or preventive maintenance is very important to keep coding machines stable. Do not wait until the machine breaks down before making repairs. With scheduled maintenance, potential problems can be detected earlier before causing production to stop.
Preventive maintenance can include:
- Cleaning the printhead or nozzle
- Checking ink pressure
- Checking sensor condition
- Inspecting cables and connections
- Replacing filters according to schedule
- Checking print quality
- Calibrating print position
- Inspecting software and machine settings
Consistent maintenance helps extend machine life, maintain print quality, and reduce the risk of sudden downtime.
Integrate with Vision System
For industries that require high quality control, using a vision camera system can help reduce the risk of failed product coding. This system can check whether the code has been printed, whether the barcode or QR code is readable, and whether the print position is correct.
Benefits of vision system include:
- Detecting products without codes
- Checking print quality
- Reading barcodes or QR codes
- Reducing human error
- Rejecting nonconforming products
- Supporting production traceability
With an automatic inspection system, companies can prevent problematic products from entering the next stage.
