Dislikes: I have a MP6001 that will duplex 8.5 x 11 copies, but jams when duplexing 8.5 x 14 and 11 x 17. I get J069 (Duplex Entrance SN: Lag) and J023 (Duplex Exit SN: Late) jam codes.
MP6001 Duplexes 8.5x 11 Only
I have a MP6001 that will duplex 8.5 x 11 copies, but jams when duplexing 8.5 x 14 and 11 x 17. I get J069 (Duplex Entrance SN: Lag) and J023 (Duplex Exit SN: Late) jam codes.
I would look for dirty or bad sensors and duplex drive slippage.
Agree with Slimslob............dirty sensors are a common cause of this and also those sensors do go bad and need to be replaced sometimes but had one last month jamming on letter size that proved difficult to diagnose. Ended up being slight flat spots on the duplex rollers at the inlet causing a hesitation in feed. At 60 copies per minute.....it doesn't take much of a hesitation to throw a jam code.Originally Posted by Toner Man

One thing I ran into on these (more common than you would think), is the white idler rollers right at the duplex entrance (in the fuser/exit unit) were popped out of place due to the tension spring either missing or deformed. Check all the idle rollers in the unit and clean the duplex rollers (large rubber) with de ink.
Again, not to overlook the simple cause, someone didn't manually select 8 1/2x11 on the tray size instead of auto-select in the lower trays did they? I guess I'm asking if the display matches the size of paper in the tray.
His problem is not with 8 1/2 X 11. It works fine. His problem is with longer paper.
exactly. It would feed 11" fine but if it had longer paper in the tray with the machine expecting 8 1/2x11, it would show a lag jam...
Yes except the lag jam would be at the feed sensor not the duplex unit.
I concede defeat...
Try cleaning the small gray rollers after the fuser exit.......
