When the photopositive surface comes close to or into contact withthe toner-coated surface of paper, the toner layer can become shifted toward the trailing edge of the paper. This problem tends to be conspicuous when the tonerlayer is relatively high against the width of lines (about 0.2 to 0.6 mm) and, in addition, when the lines are at a right angle to the feed direction (axial direction ofthe photosensitive drum).Use the following service mode item to decrease the developing bias, thus suppressing the symptom:COPIER>OPTION>BODY>FIX-SMR0: default1: decrease the developing bias by a single step (-20 V)2: decrease the developing bias by 2 steps (-40 V)If '2' is selected, the lines can become thinner.
