C. Notes
Paper dust inside the printer may lower the print quality. In this
case clean the printer as follows.
1) Open the printer cover and remove the paper if exists.
2) Clean the print head with a cotton swab moistened with
alcohol solvent.
3) Clean the platen roller and paper end sensor with cotton
swab moistened with water.
4) Insert a paper roll and close the printer cover.
The remained amount of paper detected by paper near end
sensor varies with the diameter of the paper core.
To adjust the remained amount, contact your dealer.
