There is a mark pen printing unit in RJ-F 600/900/1200 Thermal Paper Slitting Machine. How to use it? Is it different from ink wheel printing? What’s the advantage of mark pen printing? How to adjust it?

Today we are going to introduce this section.

Mark pen printing brief instruction


It marks the end strips of the finished rewinding thermal paper roll. Once the colored second appears, the user will know that he needs to change a new roll into the fax machine, cash register machine, or other printer machines.


The printing is cleaner, with no water-ink or oil ink splashed onto the process rollers of the machine.

The ink will not dry too fast in winter (under try weather). The ink restores in the ink pen body.

It is very convenient for the worker. He no needs to cover the inked plate after he finished working anymore. Just put the mark pen cap back is okay.

Ink plate with wheel printing, it cost more time for cleaning after finished working. The ink will try faster in the air. Also, it makes the rubber traction roller surface uneven. The traction performance will be worse day by day. Which operator will not notice it until half or one year later.
