Perform a factory reset on the Letratag LT100H label printer

56 Comments

To perform a factory reset on a LetraTag printer, just do this:

  • Switch the Letratag printer OFF 
  • Remove the tape cassette
  • Press the following 3 buttons together and hold - [ON] + [Numlock] + [J]
  • An erase message will be displayed and the machine will switch off

When you switch it back on it should have been reset and will ask for the language.

 

Bonus: New case available for LT100H printers!

Case only, printer and accessories not included!

Worked perfectly! Was about to dump this one, bought in 2019, and buy a replacement, so this is a big saving. Thank you.10

A factory reset will just fix some software errors, it won't fix a broken motor.

My Dymo Letra Tag 100 H is only new & only used a few times. It will not turn on. I have replaced the batteries, still not on. I have removed batteries & held on button for 30 secs, replaced batteries, still not on.

The factory reset obviously won't work if the machine will not even power on.

My Dymo Letrtag 100H is almost new and barely used. It will not turn on even after changing all four batteries, twice with different brand AA batteries. I've tried several trouble shooting recommended steps, still not working.
What's going on with this product??

It sounds like it's faulty. If it's almost new then it will be in warranty, so go to the Dymo website and they will advise have to get a free replacement.

Reset does not cause dymo Lecratag to show erase message. It shows A with horizontal line then three vertical lines. Doesn't ask for language when turned back on. It has one vertical line in the middle.

what was the problem you were having that caused you to try a factory reset?

Will not go back to English language, tried the above reset and nothing seems to make it give that option

Do you get the erase message when you perform the reset? If so then when switched back on it should prompt for the language. If you don't get the erase message then you may not be pressing the buttons correctly. Also, this is specifically for the LT100H, so won't work with other models.
