Question about Lexmark T644 Laser Printer
Probably one of the sensors on the fuser is not working correctly. There are two sensors on the back of the fuser that move when the paper exits the fuser. Remove the back of the printer when the printer says there is a jam and move the sensors to see if the error goes away. If so you may have to replace the fuser unless you can just replace the defective sensor.

Tips for a great answer:
Causes of jams
NOTE If you are experiencing jams in the duplex paper path, make sure that the duplex-tray
lever is set to the correct media size for your country/region. Open the duplex-paper-path door
and look at the embossed arrow on the lever. Make sure that it points to the media size for your
country/region. If the size needs to be changed, push the lever all the way in for duplex printing
on letter- and legal-size media, or pull it all the way out for duplex printing on A4-size media.
Occasionally, paper or other print media can become jammed during a print job. Some causes include
the following events:
? The print media that is being used does not meet HP specifications.
? The media is damaged or has objects attached to it, such as staples or paper clips.
? The environment in which the print media was stored is too humid or too dry.
? The input trays are loaded incorrectly or overfilled, or the media guides are not set correctly.
? Too many sheets have accumulated in an output area, or sheets are blocking an output area.
? Media is added to or removed from an input tray during a print job or an input tray is removed from
the all-in-one during a print job.
? The cartridge door is opened during a print job.
