Theory of Operation 2-27
If the ADC Shutter Fail test detects a problem, check the connector and the shutter for
a binding or out of position condition. If these actions do not resolve the problem,
replace the MOB Assembly.
If the following values all equal none, the test has detected no problems
â– LD Illum Warn = None
â– ADC Patch Fail = None
â– VBCR Warn = None
â– V Bias Warn = None
If Ave RADC Trans is within +/-20 of RADC Target, then printer logic assumes the
density is correct. Values on the front panel are:
Front Panel Message Typical Values
[YMCK] RADC Target = [XXX] [YMC] 375-394 [K] 460
Ave RADC Trans = [within +/-20 of RADC Target] [YMC] 369-393 [K] 467
Ideal LD Ill = [XXX] [YMC] 335-361 [K] 394
V Bias = [XXX] 887
V BCR = 0 0
