Adjusting the Platen Gap
Adjust the platen gap when you have performed either of the following:
Use the following steps to adjust the platen gap.
1. Remove the carriage cover frame assembly. (See page 1-16.)
2. Remove the ribbon cassette cover. (See page 2-128.)
3. Confirm that the print head unit is located on the right side of the printer. Connect the
power supply unit to the printer. Turn on the printer power switch.When the printer head
unit touches the left side of the printer, turn off the printer power switch. (See Figure 3-8.)
Then, confirm that the platen is closed. After the printer finishes the power on test, remove
the power supply unit from the printer. (This procedure closes the platen.)
Note:
When you are adjusting the platen gap, you must close the platen. There are instances where the
platen is open on this printer after assembly because of positioning of the gears and cams. Therefore,
you must always use the procedure in step 1 to close the platen.
4. Use 0.45 mm and 0.50 mm thickness gauges. Insert the thickness gauges from the side of the
print head unit, as shown in the figure below.
