PROCEDURE
CAUTION
The drum can become light-shocked if
exposed to external light sources for three
minutes or longer. The result is poor print
quality performance (usually appearing as
dark streaks). This can be corrected in most
cases by “dark resting” the drum (with the
machine in Standby and all covers properly
installed). Do not allow the drum to be
exposed to external light sources.
1. Select the SERVICE Menu and print the
PQ Set test patterns. These test patterns
are generated in the ESS.
2. Print the IOT Test Pattern.
3. Inspect the test prints for image quality
defects.
NOTE: If a defect is present on both
prints, the defect is probably IOT related.
If the defect is not present on both prints,
the defect is probably ESS related. Be
careful with this assumption however,
since the IOT test pattern may mask some
defects.
NOTE: Look carefully at the basic colors
(K, C, M, Y). If a defect only shows on
one of the basic colors, suspect a
developer related problem.
4. Locate The Defect in Table 1, and perform
the corresponding corrective action.
