Thermal Label Printer Maintenance

Follow these tips to keep your thermal label printer operational.

Keeping a thermal label printer operational is essential to many businesses. Up-time can mean the difference in meeting company goals. Here are 10 thermal label printer maintenance tips to follow.

Tip 1
One of the greatest failures occurring in thermal label printers is due to the printheads not being cleaned regularly. A good rule of thumb is to clean the printhead on each of your thermal label printers every time you replace a ribbon or roll of paper. It takes only about a minute and this action could save you thousands of dollars over the life of the printer. Follow the instructions in your User’s Manual as to the type of cleaning solvent to be used for your specific model.

Tip 2
If you feel you are burning out printheads too often on your thermal label printer, you may want to check your User’s Manual for the recommended heat and darkness settings. An incorrect setting often will reduce the printhead life and could cost you thousands of dollars over the life of the printer.

Tip 3
Dust residing on the Media Sensor can cause major service issues. The Media Sensor is the mechanism that insures that the gap between the paper and the printhead remains constant. Most people purchase a bottle of “canned air” and simply give the Media Sensor a few quick blasts of air, which will usually clear out any dust residue left over from the roll paper. You should consider doing this regularly, every time you change the ribbon or a roll of paper. It will only take a few seconds and it will ensure more up-time.

Tip 4
If you are using a ribbon in your thermal label printer, be sure that it is a good quality ribbon. Lower cost ribbons are often not manufactured to the exact wax and/or resin specifications of your printer and could cause a wax build-up on the platen. Wax build-up can cause poor print quality resulting in barcode reliability issues.

Tip 5
If you are using a thermal label printer that does not use a ribbon (typically called a Direct Thermal Label printer vs. a Thermal Label Transfer printer that does use ribbons) and you are constantly having problems with defective printheads, you may want to consider either changing your printer to a Thermal Label Transfer printer or using a better quality paper. A Thermal Label Transfer printer, due to the position of the ribbon between the printhead and the label paper, can greatly extend the life of thermal printheads, as paper is not directly rubbing against the printhead itself and causing friction.

Tip 6
A good rule of thumb, when purchasing new ribbons on thermal label transfer printers, is to purchase a ribbon that is slightly wider than the actual labels that you are using. For instance, if the label that you are using is 4.1″ in width, then you may want to consider purchasing ribbons that are 4.33″ in width.

Tip 7
Are you wearing out printheads? If so, here is something you may want to check. Be sure that you are not using low grade label paper if you are using Direct Thermal Label printers. Often bargain priced rolls of paper really are not a “bargain”. Why? Because low grade paper often is coarser and can cause more wear on the printheads. We have seen situations with even as high as 50% more wear on the printhead. As you may know, printheads in thermal label printers are very expensive. It may make sense to pay a little more for paper, as it is a fraction of the cost compared to replacing printheads more often. Remember, the manufacturers of thermal label printers consider the printheads as consumables that the end-user is responsible to replace. These consumables run into the hundreds of dollars each.

Tip 8
Do you have burned-out printhead elements on your thermal label printer? Here is how to tell with a PAUSE TEST. There may be situations where it looks like information is missing on your labels and/or barcodes when they are being printed. There is always a chance that one or more of the print elements in your thermal label printer printhead may be burned out. Before calling someone for thermal label printer repair, you may want to try this simple test that only takes a few moments to see if in fact it is your print elements. Keep in mind that some manufacturers considers printheads as consumables and they must be replaced from time to time. Typically, this is performed by a qualified printer repair technician. This self test can be used to print test labels when you make adjustments to the thermal label printer’s mechanical assemblies to determine if any of the printhead elements are not working.

Tip 9
What are printer and print server alerts? Should you pay attention to them? Alerts give you the ability to proactively manage your thermal printer and print server. If the printer or print server has an error, you would be sent an alert notifying you of the situation. The manufacturer Zebra uses ZebraNet Bridge that gives you control to monitor your bar code printers from anywhere, and documents the alerts to a log file. A soon as ZebraNet Bridge receives an alert, the alert appears in the Events tab. If you have not viewed the alert yet in the Events tab, the box in the status bar at the bottom of the application shows:

  • New alert
  • Alert type
  • Alert severity by color

You can configure ZebraNet Bridge to notify you by blinking the application tab in the task bar. Remember, ZebraNet Bridge only logs alerts that occur while the application is running. A good Zebra repair company sees this issue often and will be able to supply you with a new Zebra printhead and will also fully check out your Zebra printer. A steady program that includes Zebra printer maintenance will help you keep your printer up and running longer. Check with the manufacturer of your thermal label printer to see what they offer to manager your thermal label printer.

Tip 10
Clean the exterior and interior area of your thermal label printer often. To keep your thermal label printer running optimally, remember to clean the interior and exterior of the printer. When these areas are dirty, the chance of debris getting into the wrong area is increased. To clean the exterior surfaces of the printer use a lint-free cloth. Do not use harsh or abrasive cleaning agents or solvents. If necessary, a mild detergent solution or desktop cleaner may be used sparingly. You should inspect the interior area after every four rolls of media. Remove any dirt and lint from the interior of the printer using a soft bristle brush and/or vacuum cleaner. A good thermal label printer repair company sees this issue often and will be able to supply you with a new thermal label printer printhead and will also fully check out your thermal label printer. A steady program that includes thermal label printer maintenance will help you keep your thermal label printer up and running longer.

One of the best ways to protect your thermal label printer is with a printer service contract. Having a professional certified technician doing preventative maintenance and doing responsive repairs, can make a big difference.
