Repairing Honeywell Scanners

For years, Honeywell/LXE has produced some of the most reliable and easy-to-use technology in warehouse management systems.

Fully integrated systems combine with ergonomic design to make Honeywell/LXE scanners both intuitive and versatile. And their solid structure can also make them a workhorse in any warehouse manager’s arsenal.

However, even the most vigorous workhorses occasionally require some upkeep – sometimes they even need minor or major repair. Most of the time you can manage this on Honeywell/LXE scanners with simple knowhow, but there are occasions when you must make a determination on whether to seek outside help for a malfunction. If and when you do cross that road, it’s a good idea to know who to trust with repairs – an ally that will not only do the job effectively but at a price that makes repair worthwhile over replacement.

But before you get to that point, let’s take a look at some of the troubleshooting that you can handle on your own.



As with any piece of technology – even one that is meant to be handled and is as tough as a Honeywell/LXE scanner – you do have to be mindful of its overall condition. This includes its cleanliness, specifically the scanner window.

Reading performance may degrade if the scanner’s window is not clean. Therefore, if the window is visibly dirty, or if the scanner isn’t operating well, clean the window with a soft cloth or lens tissue dampened with water (or a mild detergent and water solution). If you do employ a detergent solution, make sure to then rinse the window with a clean lens tissue dampened with water only.

You may also clean the scanner and base’s housing in the same way.

Allow at least 10 to 30 minutes (depending on ambient temperature and humidity) for any washed items to air dry before applying power to cradle.

Your scanner and its base housing cables and connections must also be continually inspected for wear or other signs of damage. A badly worn cable or damaged connector may interfere with scanner operation. If either is damaged it must be replaced.

If you must replace an interface cable, please follow these steps when inserting the new cable in a corded scanner:

  • Turn the power to the host system “off.”
  • Disconnect the scanner’s cable from the terminal or computer.
  • Locate the small hole on the back of the scanner’s handle. This is the cable release.
  • Straighten one end of a standard paper clip.
  • Insert the end of the paper clip into the small hole and press in. This depresses the retention tab, releasing the connector. Pull the connector out while maintaining pressure on the paper clip, then remove the paper clip.

To replace an interface cable in a cordless scanner base, please follow these steps:

  • Turn the power to the host system “off.”
  • Disconnect the scanner’s cable from the terminal or computer.
  • Turn the base upside down and locate the pinhole for the cable release and insert a straightened standard paper clip.
  • Pull the connector out while maintaining pressure on the connector release clip.
  • Replace the new cable
  • Insert the connector into the opening and press firmly. The connector is keyed to fit in just one way and will click into place.

Next, let’s move beyond maintenance and take a look at troubleshooting.

If you run into any problems with your Honeywell/LXE scanner, please attempt these quick fixes before proceeding to the next step and contacting a professional for further help.

First, understand that your scanner automatically performs self-tests whenever you turn it on, so it should alert you to any issues any time it is turned on.

Next, you should always keep your software up to date on your scanner, and you can ensure that you have the latest versions installed by visiting to check for the latest software.


OK, now let’s look at these relatively simple troubleshooting solutions – first, we’ll look at corded scanners.


Power solutions

The absolute first step is always the simplest. Is the power “on?” Yes, I know this seems downright silly, but you would be surprised how many times people have forgotten to check this step.

Next, ensure that the laser aimer is turned “on.”

If the laser aimer is still not illuminated, ensure that the cable is connected properly, the host system power is “on” (if external power isn’t used) and that the laser button itself works.

Symbol reading problems

If the scanner isn’t reading symbols properly, check that the scanner window is clean and that the symbols aren’t smeared, rough, scratched, or exhibiting voids. Also, be sure there are no water droplets on the surface and that the symbols are enabled in the scanner or in the decoder to which the scanner connects.

Barcode is displayed but not entered

If the barcode is displayed on the host device correctly but you still have to press a key to enter it, then you need to program a suffix. Programming a suffix enables the scanner to output the barcode data plus the key you need to enter the data into your application.

Scanner won’t read a barcode

If this happens, scan sample barcodes that you know work. If those read, then make sure the scanner that won’t read is not damaged or compromised by water droplets. Next, make sure that your bar code symbology is enabled.

Next, let’s look at some troubleshooting for a cordless system, starting with the base:

Red LED is not illuminated

First, check to see if the power cable is connected properly and that there is power at the power source. Next, ensure that the host system power is “on” (if external power is not utilized).

Green LED is not illuminated

First, check that the scanner is correctly placed in the base. Next, check to see if there is external power or host power and then ensure the contacts are clean. (For Voyager 1202g only: ensure that the charge mode is turned “on.” And then ensure the battery is not bad or deeply discharged. In some cases, the scanner’s battery may slowly lose its charge to bring it into an acceptable level and then transition to a normal charge cycle.)


Next, let’s take a look at the cordless scanner itself. First, ensure that your scanner’s battery or instant charge pack is, in fact, charged.


Scanner has trouble reading symbols

If your scanner is not reading symbols well, check that the symbols are not smeared, rough, scratched, or exhibiting voids. You should also ensure the symbols are not coated with any frost or water droplets on the surface. You should also ensure that symbols are enabled in the base or Access Point to which the scanner connects.

Barcode is displayed but not entered into the application

Understand that if the barcode is displayed on the host device correctly, you still have to press a key to enter it (the Enter/Return key or the Tab key, for example). In order to make sure that it works correctly, you must program a suffix. Programming a suffix enables the scanner to output the barcode data plus the key you need (such as “CR”) to enter the data into your application.

Scanner won’t read barcode at all

First, scan the sample bar codes that you know are reading. If the scanner reads the sample bar codes, check that the troubled bar code is not damaged or compromised by something such as water droplets. Next, verify that your bar code symbology is enabled.

Troubleshooting Common LXE MX7 Terminal Problems

One of the popular models of barcode terminal we sell and repair is the Honeywell MX7 and MX7T. Now, in case you’re confused about your model, this model was formerly the LXE MX7. Honeywell acquired LXE’s parent company in 2011.

These models are a high-performing wireless barcode terminal / mobile computer with a lot of great features. They offer voice command options and an easy-grip handle. It operates on a Windows OS and offers ample storage in both ram (128MB) and flash memory (1GB-4GB). This terminal comes with keypad options of both 55 and 32 keys. This model has an LED backlight and a 3.5” VGA TFT color display. It also has a resistive touch screen and stylus pen. It offers a cordless option through the use of 802.11b/g radio & Bluetooth connectivity, as well as USB and RS-232 interfaces for additional connections. The MX7 uses a rechargeable lithium-ion battery. And while this model isn’t quite as rugged as some of the bar code terminals in terms of temperature range, but it can endure some drops of 5ft. and 6ft.

Troubleshooting Common Problems

There are normal issues that business owners need to watch out for, and a few tips you can try before you get a professional to help you out. This article won’t cover every issue you may face, but it can help you better understand your machine and how to fix simple issues. If you have a serious issue, like a cracked screen or an unresponsive stylus, you may want to reach out to a professional technician. But for minor issues and issues that you can do yourself and save a bill, read on.

Blinking LED Lights: Should I be Concerned?

This terminal is designed to blink. But what does it all mean? The MX7 has an LED light that blinks to communicate with users any possible issue that is arising. Sometimes you just want to know what’s going on and what each signal means. Here are some color codes from the manual and what they indicate.

For the System Status Update
• Red Blinking – This means a power failure. Replace the battery or plug in to the power source.• Red Steady Light – This warning sign means the main battery is low.
• Green Blinking – This just means the Display is off. Nothing to do.
• No Color – The MX7 is either fully on or in Suspend mode.

For Scanning Status
• Steady Green – This means a good scan has occurred.
• Steady Red – The scan is in progress.
• No Color – This means the imager is ready for use
• Steady Amber – The bar code decoder images is changing settings/parameters

Alpha Mode
• Steady Green – This means the 32-key is in Alpha character input mode
• No Color – This means the 32-key is in Numeric input mode

Power Issues

Strain Relief Clamps. If your power isn’t working well, or maybe it goes on and off intermittently, check to make sure the cord is connected firmly to the computer console. Over time, the way the machine was installed and the arrangement of the power cords can work loose or damage connectors. That’s why Honeywell designed the strain relief clamps to help provide tension relief on the connection. If yours is loose or wiggly, it may be this is your main issue.

Battery Charger Won’t Work Right. There are several issues that could be going on here. As the manual explains, sometimes the charger doesn’t fit in the pocket correctly, or the LED may be on without a battery pack. At other times No LEDs will fire up or the LED is flashing red in any pocket. For any of these types of issues, be sure and check to make sure you have the correct manufacturer approved battery pack, that dirt or other objects aren’t in the charging pocket, or that the battery pack is making good contact with the battery. In some cases, the battery may be old and the cells may have exhausted their lifespan.

Other Minor Problems and Solutions

Unit Either Won’t Power On or It Freezes Up
Sometimes the unit won’t power up correctly or gets locked up for a while. You may have to do several things to get things back up and running. First, make sure the unit has a fully charged battery, or is firmly seated in the docking cradle with a corded power supply. Next, try a hard reset by holding the power key for 30 seconds. Power the device back up again. When the system starts to boot up, hold down the “A” key until you see “loading from SD” or “Warning do not remove power.” The manual says that if this doesn’t fix the issue, then you need to take it to a professional repair shop.

Desktop Cradle Breaks
The MX7 manual is clear that you there “are no serviceable parts in the MX7 Tecton Cradles.” Honeywell doesn’t recommend opening these units up. If your cradle becomes cracked or broken, you need to get a professional to replace that for you with a new cradle. We don’t advise doing this one yourself.

You Run out of Storage or Need to Upgrade
If you run out of storage for data, you may want to make full use of the expansion slot for SD memory. This is like your basic SD card, and Honeywell offers 1GB and 4GB cards. Don’t let a lack of storage space slow you down. This flash memory can also help you make upgrades to your operating system.

Change Global Settings
Sometimes you need to tweak the settings of your MX7. In order to do this, you first need to be in Admin mode to change any of these settings. If roam trigger, channel set, DFS scan time, frag threshold, admin password, auth server, and many more mean anything to you, then check out the Global Settings tab. You may be the kind of person who likes to tweak every setting, and this is the place to do it.

“Diags” Screen
This particular screen helps you troubleshoot network issues and radio connectivity. You can use the Reconnect button to authenticate the wireless Lan, get a new IP address, start a continuous ping, gather data information about the radio and profile settings, and save the diagnostics to a file.

For some of these simple issues described above, there may be some things you can try before you pay someone to fix it, and it may be that you just need to learn how to operate your machine at a deeper level. But there are obvious issues that we haven’t covered here, such as cracked screens, an unresponsive screen or one that won’t work with the stylus, or frequent drops that have generated errors and internal problems. For the most part, these issues are best left to a professional technician. If you’re in that position, or you’re just not sure, give us a call and we’ll help you get your terminal back up and running.
