So we've heard a lod kind of cranking like gears missing sound in the unit. Happened before and after we would run 12x18 like 120kb stock is stopped. But last Saturday realise we were unable to run the prints again the noise occur when printer insialiseand I think only when duplexing.
We then realise letter size paper no, we thought it was by paper weights but soon realising that any size larger than the letter size were duplexing still with sound
Now we bought new duplexer gears and the belt but wondering if there is something else we missed?
