IQ 10 Low Image Density RAP
Low Image Density RAP. This RAP is used when the output image shows image density that is
lower than the specification.
Initial Actions
This problem can be caused by the following:
• Low toner concentration.
• Out of specification paper, especially low quality, or heavy weight paper.
• Faulty IOT Drive PWB (PL 9.
2).
• Drum past end of life.
• Developer past end of life. Check the HFSI counters for the Developers. Refer to Detailed
Mainte
nance Activities in Service Call Procedures.
• Faulty ADC Sensor.

TC Sensor RAP.
Replace the paper presently being used with new 24 lb. Xerox COLOR Xpressions (NASG), or
90 GSM Colort
ech + (ESG) paper and run test copies. If the images reproduced are still of low
density, continue with this RAP.
Procedure
Clean the ADC Sensor and run ADJ 9.1.1, Max Setup. The Setup runs successfully.
