I ordered the no-name compatible toner. Should be here in a few days. We'll see if it works.

The printer seems to be happy, but I'll know better after it's gotten more use. Interestingly, when cleaning the rubber grabber you highlighted, it appears that the rubber is cracked and distressed. It's not smooth like it should be, which could certainly explain it's occasional inability to grab the paper. We'll see soon whether or not more invasive repairs (e.g., replace the rubber part) are necessary.
