SUBJECT: SC285, SC387, SC388 OR SC389
SYMPTOM:
An SC285, SC387, SC388, or SC389 can sometimes occur on machines that printout primarily in B/W
mode (total color to B/W page ratio of 1:100), such as when using the machine primarily as a FAX.
CAUSE:
Color development units are activated at power OFF/ON, jam recovery and process control (ID sensor
pattern), which slightly charges and consumes the toner. However, the units are inactive and therefore toner
is not replenished when printing out (primarily in B/W mode triggering the SC).
SOLUTION:
1. Set SP3-125-003 to a value of 2 to enable Job End & Non-use Self Check Mode.
NOTE: This will instruct the machine to perform Auto Density Adjustment every 200 prints at the next job
end (operation lasts approximately two to six minutes).
2. Set SP3-125-005 to a value of 0 (disable).
NOTE: This will instruct the machine to ignore all environmental factors when performing process control.
