Handheld Stock Taking Barcode Scanner

Stock taking barcode scanner are normally called Portable Data Terminals (PDT), Mobile Computers or PDA’s (Personal Digital Assistant). They differ from normal barcode scanners in that they are portable, have memory, a keypad, a display, scanning module and powered by  a battery.

We will refer to the entry level Cipherlab 8001 as an example of a stock taking scanner.


A stock take using the 8001 PDT will normally go as follows:

  1. Scan the barcode on the shelf/bin
  2. Count the items on the shelf/bin
  3. Enter the quantity using the keypad and press Enter

Once you have completed scanning all the shelves or bins, the unit is placed in its dock, which also charges the battery. The dock will be connected to the PC with either a USB or Serial Cable. Using the standard software which comes with the unit, the scanned data is uploaded to the PC in a CSV text file format. This file can be opened in Excel or imported into your accounting/stock taking program (Check with your software vendor).

The Cipherlab 8000 range of scanners are able to be programmed with Forge Application Software which comes included in the price of the PDT. This allows the customer to change the way the scanner inputs data to suite his needs. We assist with this programming method free of charge.

The Forge Batch Application Generator and USB Drivers can be downloaded here.

Purchasing cheap barcode scanners from online stores

We receive many requests for support on Barcode Scanners that have been purchased from online stores. There are quite a few cheap unknown brands of scanners that are available lately from various online merchants.

There seems to be a lack of support from most of the online stores. Barcode Scanners and Printers can be quite complex when certain configurations need to be programmed into these units.

Its not possible for us to help clients that have bought these scanners or printers. We only deal with the Major brands like Datalogic, Honeywell, Cipherlab, Argox and Zebra. All the Barcode Scanners and Label Printers come from reputable distributors that have footprints across South Africa. All warranty and out of warranty repairs are done locally.

We only offer technical support or advice on the devices purchased from us.

Please consider the above before deciding where to purchase your Barcode Products. We offer personal support – Henry is available to chat about what model will best suite your needs or application.

Our best selling General Purpose Barcode Scanner has to be the Datalogic Quickscan Lite QW2120. The scanner comes with a scan stand and USB Cable and carries a 3 Year Warranty.

Datalogic QW2120 Barcode Scanners

The QW2120 has Datalogics “Green Spot” Technology which throws a green circle of light on the barcode after a successful read. When inserted in the Scan Stand it becomes auto sensing. This means the scanner becomes a Hands Free device, you just need to pass the barcode in front of the scanner to be scanned.

The Datalogic Quickscan Lite QW2120 USB Kit normally sells for about R650 including vat, depending on the exchange rate at the time the scanners are brought in to South Africa.

Barcode Label Printer Repairs

Barcode Label Printer Service

After many hours of operation a Label Printer accumulates dust and dirt that can be harmful to the Thermal Print Head, Platen Rollers, gears or belts and the Main PC Board. It makes sense to have your barcode label printer serviced after a years operation. 

The service consists of:

  • Stripping the printer for visual inspection of all moving parts etc
  • Cleaning the Thermal Print Head
  • Cleaning the Platten Roller
  • Cleaning all gears, bushes or bearings
  • Cleaning the PCB Boards of dust or other contaminates
  • Washing the covers, metal or plastic
  • Greasing bearings or bushes if applicable
  • Re-assembling the label printer
  • Testing the full operation of the label printer and reporting any worn parts or faults to the client

A full service costs R350 excluding vat and excludes any spares that might be needed.

Argox Barcode Printers

Argox iX4-250 Industrial Printer Review

This week we had the opportunity to test and review the newly released Argox iX4-250 Industrial Label Printer.

In The Box

The printer fits snugly and securely inside the box and won’t be damaged in normal transit. The box also contains the CD with the drivers, Bartender UL and Utilities for the Argox printers. A power cord and USB printer cable is also included.

Unpacking the printer is relatively easy and was ready to test in no time.

Loading the Media and Ribbon

We used wax ribbon 110mm wide by 360m on 25mm core for testing. The iX4-250 can accommodate ribbon up to 450m in length. Loading the ribbon into the printer is easy and no different from the previous X1000V, X2000 and X2300.

There is a diagram in the lid showing how the ribbon is to be loaded. One thing to remember is – the shiny side of the ribbon is to be against the Print Head and the dull side against the paper labels.

Loading the roll of label is also no problem and similar to the previous X series printers. Care should just be taken to make sure the label goes through the guides of the label sensor. There is a diagram showing the label path.

The printer can take a label roll with a Outer Diameter of 8.26 inch or 210mm.

Operating the iX4-250

We already have the driver (Argox_2017.1_M1) installed on our test pc together with the Bartender UL (Bartender_UL_2016) label design software. The software and driver is compatible with Windows Vista, 7, 8, 8.1 and 10. Our test PC is running Windows 7.

The printer installed when we plugged in the USB cable between the Printer and the PC and switched on the iX4-250. After installation finished, we opened Bartender UL and designed a rather complex label with Text and QR Code barcodes.

The iX4-250 printed the first 10 labels perfectly at 203dpi and at a speed of 8ips.

We ran the next batch of 100 prints through the printer with the same perfect quality. Labels printed well and the alignment stayed true.

The printer runs smoothly with not much noise or vibration. We were quite impressed with the operation of the printer.

Interfaces of the iX4-250

The Argox iX4-250 comes standard with the following communication ports – Ethernet, USB Device, Dual USB Hosts and Serial (RS232). Making it ideal for most situations or applications. We tested the printer using the USB Device Port.

The iX4-250 can be further expanded with an optional WiFi module and GPIO card/Parallel port.


The printer has lived up to the quality we have come to expect from Argox and does not disappoint at all. The build is solid and the quality of the frame and metal covers are good. 

We can really recommend this printer for a high volume, heavy duty application. Operation is easy and the iX4-250 label printer is not complicated at all.

Thermal Print Head

Thermal Print Head Cleaning.

The Thermal Print Head of Barcode Label Printers are often the most expensive part of the printer. Proper care and cleaning should be done often to prolong the life of the thermal print head.

It is strongly recommended that you clean the print head when you load a new roll of media (label roll), or when you notice the print quality declines. If a label or portion of a label gets stuck on the thermal print head, NEVER use any sharp or hard instrument to try and remove the label. 

Thermal Print Head Cleaning Tips.

  1. Switch the printer off and wait until the print head has cooled down
  2. Do not use water on any part of the printer to clean the print head or casing
  3. Do not touch the print head with your hands or sharp objects
  4. Moisten a cloth or cotton swab with Ethyl Alcohol and wipe the thermal print head in one direction only. Rubbing back and forth can cause dirt to get stuck again.
  5. Let the Ethyl Alcohol dry before using the printer again.
  6. If a label has become stuck, gently peel it off with your hands and use Ethyl Alcohol to remove the residue.

Regular cleaning will prolong the life of your print head and ensure clear label prints. For any questions or advice, contact us on 011 425 5439 or


Argox Barcode Printers

Argox direct thermal label printer

Argox D4-250 Direct Thermal Label Printer

The Argox D4-250 Direct Thermal is a new model from one of the leading manufacturers that supports a wide range of applications at an affordable price.

We often take a product and take an in depth look at its design, construction and workings. Last week it was the Argox D4-250’s turn. The printer was put through its paces with very satisfactory results.

Firstly lets look at its features.

  • Compact size, unit really has a small footprint, ideal for desks or tight spaces.
  • The Clam Shell design makes it easy to load rolls of paper labels
  • The connectivity is great! The printer has onboard USB Host, USB Device, Serial and Ethernet. Making it ideal for most applications.
  • If wired connectivity is a problem, the D4-250 can be expanded with a WiFi or Bluetooth module – Great!
  • The Argox D4-250 has received Cerner Certification!
  • The printing speed of max 6 ips produces great prints.

After testing the printer we came to the conclusion that the D4-250 really lives up to the claims made by the manufacturer and could not fault the printer and can really recommend the printer for low to medium volume use.

The cost of the D4-250 is normally *R3 698 ex vat without any discounts or special offers.

The cost of the replacement Thermal Print Head is also not excessive at *R1 445 ex vat (ARG59-D42A1-001). If care of the Thermal Print Head is taken and regularly cleaned, it can last a long time without giving the dreaded “dead lines” problem.

The cost of the WiFi module is *R3 610 ex vat (59P4201001) and the Bluetooth module is *R1 060 ex vat (59D4201001). 

*Price indicated is normal list price and correct during Feb 2018

We  recommend the Argox D4-250 Direct Thermal for your Direct Thermal 4″ label printing needs!

Barcode Scanner Repairs Barcode Scanners Faulty barcode scanner

Vertical or Presentation Barcode Scanners not Scanning Effectively

If your vertical or presentation scanner is battling to scan smaller barcodes which it once did effectively, it is possibly caused by a dust buildup internally on the optic surfaces.

The laser scanners all use a rotating mirror motor which spins at high speed to distribute the laser light across mirrors to achieve the scan pattern that scans barcodes at different angles. This spinning motor causes air movement inside the scanner enclosure that sucks in dust over time.

The dust settles and coates the highly reflective mirrors causing the beam to loose its “sharpness” and scanning becomes more and more difficult.

This dust also settles on the inside of the scan window which hinders the reflected light from reaching the sensor that reads the barcode inside the enclosure. 

Don’t suffer the frustration of the barcode scanner that battles to scan – bring or send it to our Technical Guy for a thorough cleaning. All covers are washed and the reflective mirrors are cleaned and polished, PC boards are cleaned. The scanner will, after this “Service”, scan all your barcodes aggressively again.

Honeywell 3800G and 1300G Barcode Scanner Cables

Please be aware that the Honeywell 3800G and the 1300G models look similar but do not use the same cable.

The connector end of the cables differ between the 3800G and the 1300G

Apart from the physical difference between the cables, the pin configurations also differ resulting in damaged to the components on the PC Board.

The 1300G cable can not be inserted into the 3800G but we have seen cables that have pushed in with force or the end caps have been changed to allow the cable to fit. 

Please note that using the wrong cable on the wrong scanner results in a blown board which can not be repaired. Always ensure that you have the correct cable.

Repairs and Servicing of an Argox X2000+ Barcode Label Printer

Procedure explained for repairs and servicing to an Argox printer.

When we receive a barcode label printer for repairs the printer is first tested to determine any faults in the operation of the printer. The printer is then opened for a visual inspection of all the components and boards. 

At this point a quote is prepared and sent to the client for approval. Once the go-ahead has been given the printer is stripped and all components washed and cleaned. Non washable parts are cleaned with compressed air, like the PC Boards etc.

Once the printer body and components have been cleaned the printer is re-assembled and faulty parts are replaced. 

The Thermal Print Head is cleaned and checked for any scratches or replaced depending on the condition determined when initial tests were done and is fitted last.

Once the printer is completely assembled it is given a full function test and any adjustments are made to the printing mechanism. Once we are happy with the functioning of the printer it is ready to be collected or delivered to the client.

For repairs or servicing of your label printer, contact us on 011 425 5439 or

Wireless Barcode Scanners

Wireless Barcode Scanners

Wireless or portable barcode scanners can mean one of two things:

  1. Normal Barcode Scanners with no wire connecting them to a terminal but using a radio frequency or Bluetooth connection between the scanner and its base station.
  2. A portable data terminal is also sometimes referred to as a wireless scanner. A PDT is a device with a display, keyboard and a scanner that either stores the scanned data in its memory for later download or transmits the data via Bluetooth or WiFi.
Wireless Bluetooth Barcode Scanner. Portable Data Terminal or Mobile Computer

Bluetooth Barcode Scanners

As stated before, these type of scanners use Bluetooth to communicate between the handheld scanner and its base station/charger. The base station is connected to a PC or other terminal with a USB cable. The scanners are also able to connect directly to a bluetooth enabled device such as a tablet or smartphone etc.

The working range between the scanner and its base station varies from 10 to 100 m depending on the manufacturer and model. The scanners use re-chargeable batteries for power and these are charged when the scanner is placed into the base/charger. The number of scans that the scanner can do on a charge average about 40 000 scans but again it depends on the manufacturer and model.

The Honeywell Voyager 1202g-bf wireless scanner does not use a battery but rather a “super capacitor” to power the unit, a first in its class! The scanner when placed in its charger takes about 35 seconds to charge and this will provide enough power for at least 100 scans.

We at JNS Technologies aren’t tied down to a specific brand of printer enabling us to offer you the printer to best suite your application.

There are two methods used to print barcode labels namely:

  • Thermal Transfer more commonly known as “TT”
  • Direct Thermal more commonly known as “DT”

Thermal Transfer Method uses an ink ribbon situated between the thermal print head and label. Heat from the print head essentially burns the ink onto the label creating a clear long lasting print.

Direct Thermal Method uses no ribbon but prints directly on the label. The labels have to be thermal paper labels similar to the older fax machine prints. These labels are not long lasting and are easily scuffed and affected by heat and moisture.

Barcode Software

Most barcode printers come with a free version of label design software, drivers and other utilities.

If you need more functionality that what the free versions offer then there are software packages available that can be purchased.

The free versions like Bartender UL which ships with the Argox printers allows you to create labels with text, simple graphics and a barcode. The labels can be saved and used again when desired. The Bartender UL package is normally all that is needed, we have very few clients that have purchased other additional software.


JNS Technologies does not directly deal with label sales but we will depending on your location suggest a company in your area that can supply you with the labels according to your specifications.

Thermal Ribbons

Thermal Transfer ribbons are available from us in different sizes to fit most of the popular printers. There are three types of ribbon available for the different label material. When speaking to your label supplier they will be able to suggest which type of ribbon will be best suited to the label you are purchasing.

Ribbon types are:

  • Wax Ribbon
  • Wax/Resin Ribbon
  • Resin Ribbon.

When you order ribbon from us, please give the following information

  • Length of ribbon
  • Width of ribbon
  • Core size or printer make and model

Problems with Barcode Printers

Are you having a problem with your printed barcode labels? We will try and give examples of all the faults and how to remedy them.

Barcode scanners not able to read your printed label

The most common cause of scanners not being able to read barcodes  printed on labels is caused by dead pixels on the Thermal Print Head. These dead pixels result in missing lines in the barcode. Clean the Thermal Print Head with isopropyl alcohol and a soft cloth to remove any dirt from the print head. Never use any abrasive or sharp object to remove dirt or stuck labels as this will damage the print head. If the labels are still not printing correctly after cleaning then you will have to replace the Thermal Print Head.

Printed labels have sections where the print looks lighter or is missing

If you look at the printed label and part of the print is missing, smudged or light then follow the steps above to clean the Thermal Print Head or have it replaced.

Printed labels are too light or look dark and smudged

When looking at the labels and the print is dark and smudged or is feint then change the heat setting of the print head either higher or lower and re-test the print. This problem can also be caused by an incorrect ribbon type for the labels you are using. Ribbons come in three types – Wax, Wax Resin and Resin. Speak to your label supplier to find out which type of ribbon will be best suited to the label material.

Printer printing across two labels or skipping labels

The common cause of skipping labels or not aligning the print correctly on the label is the Media Sensor. The media sensor detects the gap or black line between the labels allowing the printer to “know” where the label begin and ends. Locate the media sensor and run a soft clean cloth over the sensor to remove any dirt from it. after installing the label through the sensor, press the feed button to test, after feeding one label the printer should stop. The problem can also be caused by having the size of the label incorrectly set in the software you are using on the computer. Having the label dimensions larger than what the physical label is can also cause misaligned print and skipping labels. If after cleaning and checking the dimensions you still have the problem then the media sensor is possibly faulty and will need to be changed.

Printer making grinding noises or is excessively noisy

The label printers use either belts or gears to drive the mechanisms that move the platten roller and ribbon take up spools. These do wear over time and need to be replaced. We suggest having your printer serviced every six months so that parts can be cleaned or replaced.

Barcode Scanner not working?

Are you facing the frustration of a barcode scanner that is not working as it should? We will in this article try and give you ideas of what to look for to rectify the problem you are having.

Not scanning barcode. 

If you are pointing the scanner at the barcode and activating the trigger and not getting any audible or visual indication that the barcode has been read it is normally due to a dirty scan lens. Check the scan lens for dirt or smudges. Clean the lens with a soft cloth moistened with some water or mild detergent. If the scan lens is badly scratched or chipped you will need to send the scanner for repair to have the lens changed or polished.

Scanning barcode but nothing appearing on connected device.

If you have scanned the barcode and got the audible and visual indication of a good read but nothing gets transmitted to the PC, POS Terminal or other device then check the following:

  1. Check that the scanner is set to the correct interface (Cable).  Reprogram the scanner using the programming manual to correct interface.
  2. Make sure cables are properly plugged into the scanner and host. If using a USB scanner, unplug from the host and plug back in. Check the condition of the cable and connectors. The cables eventually harden at the scanner side causing the internal wires to break.
  3. If using a keyboard wedge cable check that no pins have been bent or broken off inside the PS2 connectors.

The scanner causes an error on the software running on the host.

Check the suffix and prefix programmed into the scanner. This type of problem is mostly caused by incorrect or missing prefixes or suffixes. Use the programming manual to set the scanner back to factory default then set to the correct interface with a suffix of CR (Carriage Return). This normally sorts out most of the communication problems or errors.

Scanner completely dead.

Here are a couple of guidelines for you to check:

  1. Check condition of cables and pins if applicable, make sure the cable is securely plugged in to the scanner and the host terminal.
  2. If an external Power Supply is required and being used, check that it has an output voltage and is securely plugged into the appropriate receptacle.
  3. If using a USB interface scanner plug the cable into another USB port on the host. It is possible that the USB port is faulty or dead.

If none of the above helps to solve the problem you are having contact us. Our technical department will do its best to have the unit repaired in the shortest time possible. All faulty scanners are to be sent to our premises for repair, we unfortunately do not do any field repairs.
