Troubleshooting the Printing System 7-73
Repetitive Defect Ruler
Repetitive print defects are usually associated with a specific roller
within the printer or the Toner Cartridge. Use Figure 7-9 to isolate the
cause of repetitive print defects. Align the first occurrence of the
defect with the top of the “ruler” and measure to the next occurrence
of the defect to determine the roller in question. When you are certain
that your defect pattern matches the pattern of the ruler, replace the
indicated roller.
