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.
