MONITORING OF COLOR DEVELOPER HOUSING IN A TRI-LEVEL HIGHLIGHT COLOR IMAGING APPARATUS

摘要

In a single pass, tri-level imaging apparatus, machine cycle downis initiated when the color developer housing is functioning improperly.The voltage level of the color image prior to its development is read usingan electrostatic voltmeter (ESV). The voltage level thereof is also read afterdevelopment. The difference between these two readings is compared toan arbitrary target value and a machine cycle down is initiated if thedifference is greater than the target.
