1: Enabled
Enable this SP mode when dirty background
and/or firefly spots appear intermittently on prints
with a low image area ratio.
While making prints with a low image area ratio,
developer is agitated with less toner supplied. This
may cause the toner-carrier attraction force to
increase or toner to coagulate.
This sometimes causes firefly spots or dirty
background when a large amount of toner is
supplied.
NOTE:
When enabling this SP mode, the following
SP modes should be changed.
SP3-906-001 Job End Process Control Self-check
