Thermal Printer & Printhead Maintenance Tips
With the development of thermal printing technology , we get familar with the thermal printers,like POS printer.The common thermal technology advent is lottery. However most of the users don't know much about the maintance of printer except for the normal operation.
This time we will introduce how to do that .
There are a number of factors that an impact the performance of your printer – humidity, dust, heat, wear on the printhead and printer compents , and paper stock used when printing. It’s important to keep the printer’s environment as clean as possible and to use high quality supplies and materials for the best results.
The most critical element to ensure clear, high quality printing is the performance of the printhead. If it is dirty, clogged, worn or abraded, the quality of the printed product will degrade. Cleaning and maintaining the printhead will extend the useful life of the printhead, and your printer. And, as printheads are expensive, maintaining it and extending its useful life will result in cost savings for your operation. Some maintenance tips are:
Clean the printer frequently to remove dust and residue from paper, foils, and the environment. It is recommended that the printer be cleaned two to three times a week in moderate use operations.
Clean the printhead to remove ink residue, paper dust, or coating residue to prevent streaking and incomplete printing. Cleaning will also help prevent clogs which can permanently damage the printhead. Printheads should be cleaned when the thermal transfer ribbon or thermal transfer label roll is changed. As the printheads (and rollers) are fragile, you should avoid touching them anywhere expect on the edges and use only approved cleaners. The most common methods for cleaning printheads are using isopropyl alcohol wipes or swabs or cleaning cards.
Isopropyl alcohol cleans the printhead, dissolving any residue without leaving residue from the cleaner. It’s important to make sure that the alcohol fully evaporates (dries) before using the printer.
Cleaning cards clean the printhead and remove any build-up on the rollers. They should be used for periodic cleaning, as they can abrade the printheads and rollers, damaging them.
Some thermal transfer ribbons have built-in printhead cleaners, providing continuous cleaning and maintenance for the printhead.
Replace printheads that have become worn or abraded.
Follow the manufacturer’s maintenance recommendations for your printer, including regular preventative maintenance. Periodic inspections of the equipment can identify potential issues before they become problems and can minimize downtime while reducing the cost of repairs and service and, most importantly, extending the life of your thermal printer.
