 Field Remedy
1. Service mode (Level 1) COPIER > OPTION > BODY > DEV-SP1 >
This service mode setting allows patch background detection at the same time as ATR patch
detection and ARCDAT patch detection, resulting in eliminating the effect of reading error from
patch detection value caused by soiled patch detection sensor. However, productivity for
shorter than B4 size paper (feed direction) declines at this setting (e.g. for A4/LTR, declining
from 70ppm to approx. 65ppm).
Note:
If feeding with the condition of high image duty (coverage), the service mode setting DEV-SP1
'00000110' may degrade hue stability. The risk of developer overflow and etc. is low for high
image duty (coverage) feeding. For that reason, change the setting to Service mode (Level 1)
COPIER> OPTION> BODY> DEV-SP1 > 00000000.
