It just looks to me like a mechanical issue. We have seen this seemingly 'fake' media jam issue in the 2300DL for a year now ('fake' because the paper never gets picked up and so never actually 'jams', but whatever). Sorry, my last message got clipped somehow. I've only just discovered this site I hope someone can help me out. I've lived with this problem a long time. I've found a couple other posts on the web with people experiencing similar problems with the 2450, but have yet to see a solution or even an explanation. I'm not sure how the printer determines the paper size as it feeds into the printing mechanism, but it seems to be misreading the dimensions. Both the printer and the computer's printer driver settings (under Win/XP) are set to Letter. Letter sized paper is all I've ever used in Tray 1. This may have been happening all along I've just discovered that the 'Input Tray/Auto Continue' option was set to 'ON' and that 'Input Tray/Tray 1 Mode' was set to 'AUTO.'

Lately I've noticed that the printer LCD panel indicates a 'paper mismatch' after the page is printed.

However, the vertical placement of the page is somewhat random: if I print the same page twice in a row there can be a vertical shift of several millimeters. As I print more pages, the downward shift becomes less noticeable. Often, the page does not fully exit the printer and I must extract the sheet and open/close the top to get the printer running again. Typically, the first page sent to the printer after a period of inactivity will have it's contents shifted downward, leaving a blank space at the top of the page. I have a three year old Konica-Minolta magicolor 2450.
