EPSON AcuLaser C1100 Revision B
TROUBLESHOOTING Printing Quality-related Trouble 243
NOTE: When horizontal stripes and spots appear at fixed intervals, it is highly
possible that a specific roll has caused the trouble. If this happens, you
might be able to easily solve the problem by measuring the interval
between the stripes or spots on a test print, and checking the relationship
between the pitches shown in the table below (note that the pitch does not
necessarily match the length of the roll periphery).
