I stole it off of an old straight shooter envelope feeder that was broken. It just leaves the stack lifted at the tail edge so It can ride up the stack instead of buckle. The only annoying part is finding a magnet so you can hold it in place.
We kinda of had the same issue. It felt like we got trained by a salesman rather than a tech/operator.
We also found making kind of a scoop for the stack instead of using the back stop helped with skew. With the back stop the sheets like to buckle when it's reading marks, but a scoop, or...
Whoever sold it to you should have come out and trained you. The manual is pretty helpful though, are you sure your registration marks are in the correct location according to the specs? The marks need to be 12.5mm from each edge. Make sure your paper size is set correctly, and be sure your...
I'd argue they've never been great. When your solution to making terrible parts is just making them user replaceable then your machine is poorly engineered. Even 20 years ago the first tech support option was "replace the drum". You'd think after 20 years they'd just make a well made drum.

A common issue for example is 4x6 postcards only fit 4up on a 12x18 sheet with a standard layout, but if you do a dutch cut (or combo cut) you can do two cards sideways and fit 6 to a sheet. I...
For what it's worth, I reached out to my own tech and he said he hasn't heard anything about it. He also checked their knowledgebase and there's nothing about Titan paper anywhere.
Techs who blame paper are bad techs. There's nothing wrong with Titan, it doesn't even have an i-tone coating on it, it just says "indigo certified". Funny enough their website even says "Canon tested". Ignore your techs, they probably just need a scapegoat because they can't solve an issue...
I think the Ricoh is a much higher class of machine than the PX500, but even if you decide on Xerox, I'd just buy the Fuji Revoria EC2100 since Xerox is just selling the same machine for more with their branding on it.
