Printer prints faint labels - Zebra Z6M Plus Thermal Label Printer

try using the manual feed tray and set it as printing labels.

See if it still happens using a fresh label roll. From the Dymo 450 User Guide the common causes of poor print quality issues.

Poor print quality is most frequently caused by one of the following:
• An old roll of labels
• Labels made by a manufacturer other than DYMO
• Labels where the thermal coating has been compromised
• A dirty print head
First, make sure you are using DYMO-branded labels. Do not use third-party labels because the thermal coating on other labels has a different sensitivity than DYMO-branded labels. Also, the perforated holes between the labels made by other manufacturers are frequently not detectable by LabelWriter printers.
If the print quality becomes faint, small dots of white appear scattered through the printed characters, or light and dark patches of printing appear, you are probably using a faulty roll of labels. Try using a different roll from a fresh box. If the second roll prints correctly, the problem is with the first roll of labels.
Another possibility is that the LabelWriter print head needs cleaning. Every LabelWriter printer comes with a cleaning card. See "Caring for Your Printer" on page 17 for information about the
LabelWriter cleaning card.

This could be a print head problem but without seeing it it is hard to say can you scan the labels and let me see them? this help with diagnosis.

probably dots broken on the print head

possible the ribbon is not the best in related to that especific labels, change ribbon.

check whether letters with faint print are coloured

You need to use or order the zebra thermal printer cleaner. It is necessary to use these cleaners every few months.

I guess that you use a non-genuine print cartridges, try to use a genuine one.

If you are using a windows printer driver then perhaps you have "Direct Thermal" selected in the printer preferences. The driver setting will override anything you have set in the printer. So every time you send a new print job the settings get changed to what they are in the driver.

TRY PUTTING NEW BATTERIES IN THE DEVICE AND THE LETTING WILL GET DARKER SO YOU CAN SEE IT
