IQ 20 IOT Graininess RAP
IOT Graininess RAP. This RAP is used when the output copy shows graininess, or a sandy, tex-
tured appearance.
Procedure

weight papers are particularly susceptible.
• Replace the paper currently in use with new, 24 lb. Xe
rox COLOR Xpressions (NASG), or
90 GSM Colortech + (ESG) paper. If the paper change does not fix the problem, go to
Detailed Maintenance Activities in Section 1. Check the expected life of the Yellow,
Magenta, Cyan and Black Developer. If the developer material is past expected life,
replace it.
• Replace the Developer Bias Brush, if damaged (REP
