Installing/replacing pens
1. Remove the printer cover and press the PEN CHANGE switch with a ball pen or the like; this causes
the pen holder to move to the right side of the printer for pen replacement.
2. Depress the pen eject lever to eject the pen which is at the top of the holder. When doing this, rest
your finger lightly on top of the pen while pushing the eject lever to prevent it from falling inside
the printer.
3. Insert a new pen.
4. Press the PEN CHANGE switch again to bring another pen to the top of the holder.
5. Replace all four pens (black, blue, green and red) in the same manner. When finished, press the
RESET switch to ready the printer for printing with the black pen.
Execute the BASIC TEST command to confirm that all colors are printed correctly.
