Have you tried 08 mode, 4546 to disable the color registration? If it works fine, then go into input/output mode, 03 and check the
sensors.
Also...just remembered this one. Drove me nuts! Does the machine have any accessories? LCF, Finisher?
If so, PLEASE check the 5 volt power supply line. Easy way to find it. Pop the top off the ADF, the larger connector coming from
the machine to the ADF, locate the wire harness connector to the ADF board. The larger yellow wire is the 5v DC line. Check it.
If it is below 4.92 volts, THAT can trigger the issue as well. On the older version of that machine, the DC power supply had adjustable
pots, but in the newer version, they took the adjustment out. The switching regulators in those, were not really up to the load requirements
when the accessories were added. Also, they had some batches of sensors that were troublesome and would "freeze" until powered off/on.
Once we started cranking the 5 volt line to around 5.1 under load, a lot of are whacky goofy problems stopped. But, like I mentioned,
some of the newer designs took the adjustment for the LVPS away.
