IQ 34 Text / Image Separation RAP
When using the Original Type options of Photo and Text or Text, the copier attempts to discrim-
inate between text and photo areas within the original. It then applies the appropriate image
processing to each area. Text is reproduced at 600 lines per inch while photos are reproduced
at 200 lines/dots per inch. On occasion, the defect may appear where an area is classified
incorrectly and text is treated as photo or vise-versa.
Procedure
•
Rotate the original 90 degrees.
•
Reduce or enlarge slightly.
•
In Photo & Text mode, change Photo Type from Half Tone to Photograph
•
Under Tools - System Image Quality - Image Recognition, the Key operator can adjust
Text & Photo Recognition and or Text & Photo Balance. It should be noted that these
parameters are not intended to be adjusted on a job to job basis. These adjustments are
trade-offs and should be treated with care.
•
Change Original Type to Photo or to Graphic & Maps. (Appearance may change - some
CQ adjustments may be necessary.
IQ 35 Toner Starvation RAP
This defect occurs at the transition point between a high density area and a low density area of
the same color. A localized area of the mag brush becomes “starved” for toner due to develop-
ment fringe field effects. Starvation tends to worsen at low triboelectric levels (high toner con-
centration).
Initial Actions
Change the orientation of the original by rotating it 90 degrees or 180 degrees.
If the machine shows a starvation problem and has Tag 14 ATC Sensor, refer to the
IQ 47 ATC
Sensor RAP
.
NOTE:
After replacing developer material, go to IQ47 ATC Sensor RAP,
Appendix 1. ATC set-
up procedure
.
Procedure
Place the Color Test Pattern on the platen and make a print in Black, Yellow, Magenta and
Cyan.
The defect is present in all four colors.
Y
N
Ensure that developer housing for the problem color is not damaged. Replace the devel-
oper if the developer is near or over HFSI threshold.
Perform
ADJ 9.1.1
Max Setup.
NOTE:
If the machine is showing objectionable starvation, and has an ATC Sensor and the
sensor is activated, go to the
IQ 47 ATC Sensor RAP
to check for proper operation.
