PLATEN ROLLER REPLACEMENT

The platen roller is a high wear component due to its treading against the print media. This

treading will eventually wear grooves into the rubber material and negatively affect print output.

1 Turn the printer OFF and disconnect the power supply cord.

2 Lift up the top housing cover (1) (See Figure 4-2) to access the platen roller (2).

3 Detach the platen gear cover (3) from the printer housing (4).

4 Lift the dispenser bar (5) upward and away from the assembly (2, 5).

5 Install a replacement platen roller assembly (5, 2) to the housing (4).

6 Lower the dispenser bar (5) and reattach the gear cover (3).

7 Load some media, close the cover, and do a test print to ensure proper function.
