HP 41.03 errors on HP laserjet 4050TN

[nkuebelbeck]

Occasional without any method to the madness this printer will show 41.03 unexpected paper size on the control panel. tray 2
Steps I have already taken
1. Verified that the paper tray is set to letter(both sets of tabs)
2. Replaced the tray completely. The top plastic clip on the right side(there are three off them) would not lock into place. read somewhere on the net this could be my problem.
3. Reset the printer settings.

This printer is setup to print from a windows 2003 server with an IP printer installed and its using the 4050 pcl 5e driver

I'm at a loss at what to try next.
