Both the xxx2ci and xxx3ci have more vivid colors.
The original fusers will squeal and give C6220, C6030, C6600 and C6770 errors. A couple of the metal shafts are made of very soft metal and very quickly wear down. The 5 second diagnosis is to carry your fuser over to counter, tip it onto the outer side and bump it on the counter. If it dumps a tablespoon of rust dust out of each end of the fuser you can be sure that you need a fuser replacement. The FR-8550H fusers seem to last longer than 170K. I think we've replaced EVERY original fuser.
For C2300, 4214, 4204, 4203:
All caused by the fuser. The belt rotation sensors detect differences in front/rear belt rotation speed. The endcaps slip on the sleeve ends ... fixed on FR-8550H fuser.
The imaging components seem to make yield.
The primary charge rollers have all the same sort of defects that you've seen of the Alphards.
The developing unit lock buttons tend to pop out by themselves. The best solution seems to be driving a small sheet metal screw into the edge between the button and the front cover:

For dog-ears, paper skew, 0523, 0524, 6511, C8100:

For 0512, 0502 misfeed:
KM-3552ci jams 0512, 0502
For 0533, 0534 we've had to increase page separation. You've probably had to adjust page separation before. Decreasing the spring tension increases the page separation. I think of it this way: More spring tension makes the separation roller follow the feed roller more. Less spring tension makes the separation follow less, resisting multiple feeds.
For 0413, 0502, 0000 won't clear:
A dusted over registration sensor will cause this.
For C8020, C8030:
The punch motor fails.
For C9040:
The original lift plate breaks at the rear post.
These machine use the empty black toner cartridge as the waste receptacle. There is a switch that is flipped on the cartridge when you remove the empty, so the machine can tell the difference between a full and an empty. So if the enduser takes out an empty black toner cartridge and tries to put it back in ... well it won't go back in. We get lots of calls for such things. It doesn't help to tell the enduser that shaking an empty toner cartridge doesn't help. ITS STILL EMPTY!
