Recently, I've been seeing more issues with Tecjet and their Eco Solvent machines that have seemingly "outdated" dongles. If you look at the attached images, at 50% scale on the print, there is no watermark. However, when you take it up to 100% scale, the watermark is automatically there, even though the dongle is plugged in. Uninstalling and reinstalling the software has no effect.
The only thing that we can do is to update the dongle firmware. Should this be needed, you can contact Perfect Laser for assistance.
Using the software is very simple: Simply have your dongle plugged into the PC (this can be done remotely too), open up the mtru.exe, then click the "Upgrade physical rockey" button in the bottom right. When it is done, the application will ask you to unplug the dongle. That's it; you are done.
While not explicitly required, I will advise restarting the PC and the printer just as a safe measure.
If your dongle does not need a firmware upgrade, the application will say "No upgrade data," like mine, and nothing will happen, so don't worry about damaging a dongle through this process.
Note: Kindly contact your nearest branch and ask to speak to a technician so that they can send you the software required to update your maintop dongle.
