Setting DIP Switches
When you open the ink cartridge cover and remove the DIP switch
cover, you will find the DIP switches. Set the DIP switches, using the
tip of a tool, such as a small screwdriver. Change settings when the
printer is off.
Cleaning the Autocutter
Adhesive from labels may stick to the fixed blade of the autocutter,
which may prevent the autocutter from cutting paper cleanly. If this
happens, follow the steps below to clean the autocutter.
1. Turn off the printer, and unplug the AC cable from the inlet.
2. Open the roll paper cover and remove the paper.
3. Remove the adhesive on the autocutter blade on the side of the roll
paper cover with an implement such as a cotton swab. If
necessary, moisten the cotton swab with alcohol.
