CLEANING THE LASER UNIT
When the laser unit inside the machine becomes dirty, line-like color irregularities (colored lines) may appear in the print 
image. When the following conditions appear, clean the laser unit.
Identifying lines (colored lines) caused by a dirty laser unit
• Colored lines always appear in the same place. (The lines are never black.)
• The colored lines are parallel to the direction of paper feeding. 
• Colored lines appear not only when the copy function is used but also when the printer function is used.  (The problem 
appears during both printing and copying.)
