Paper Replacement
When the paper roll is almost empty, vertical pink striped lines (starting approximately 8 feet from the
end of the roll) will appear on both sides of the paper. Perform the following steps to replace the paper
roll (see Figure 15-8):
1. Open the printer’s front cover
2. Press the print mechanism support at the point marked “PUSH” (on the right side of the printer)
3. Guide the paper through the paper feed slot
4. Hold down the FEED button to advance about 2 inches of paper out of the printer. This is
necessary to make the installation of the cover easier.
5. Insert the paper roll into its housing.
6. Close the print mechanism support
7. Insert the paper into the cover slot
8. Re-close the cover and tear the spare paper off
