CompTIA A+ 220-1101 Practice Question

In thermal printers, the heating element or thermal head needs regular cleaning to ensure proper heat transfer for printing. Debris or residue on the element can cause poor print quality, such as faint printing or poorly defined barcodes. Cleaning the heating element can often resolve these issues, thus improving the print quality. It's an important step before considering more drastic measures like replacing printer components or the entire printer. Changing the paper only would not address this issue if the problem lies with the thermal head. Printing a test page is a good practice after maintenance, but it does not resolve underlying issues. Adjusting printer settings in the software might help with some issues, but it's not likely to improve print caused by a dirty heating element.
