250ci issue, Kyo tech support clueless

[bronco31]

under adjustment/maintenance there's a tab for Calibration Cycle....mine is set to custom, while long/short etc is greyed out.... anyone know why? (the guys on the hotline say they don't know why its greyed out,
I may want to try it at short)


the actual problem is the usual ..intermittent/once or twice a day 7101/7102 codes, replaced K/C dev, black dev motor, firmware latest, tryed U464 AC Calibration at 0 and 2, tried seting U325 to mode4, U147 to mode1 per Tshooting bulletin, U155 shows normal, count 240K, print coverage 6% even btw color and B/W...

wait I just found a clue in the SM, something under U464 but I don't remember playing with the Set Custom on/off mode??

they do print full coverage 8 1/2X11 color prints intermittently

should I replace the engine PWB? sigh...
thx for any ideas

Yes, Custom must be enabled in U464. But there's more to it. This is the procedure that I used when increasing the frequency of calibrations:

'1) Set sim 464, Set Custom, set to On. 2) System Menu, Adjustment/ Maintenance, Color Calibration Cycle, select Custom. 3) Sim 464, "SetCalibTiming duringPrint", set to +480. 4) Sim 147, Set Operation Mode, select Mode 2. 5) Sim 464, run AC Calibration.

I've used this setting when my endusers were doing 50 to 100% fill, and getting grainy images. I'm not sure if that will help you, but that's how this function works. =^..^=

man am i running behind! thank you BC, i finally set it all back to normal calibration cycle (turned Custom off as they're doing 6% fill at the most)


what is this magical mysterious U464 AC Calibration that we are to do aftr a drum/dev change ?
are we suppose to set the ID Adjustment on each color to 0 ? (for a while there (prev firmware maybe).. i was told to set each color to 4....

At last mention the number was "2" but I honestly don't know what that number specifies. =^..^=
