Printer malfunction
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
jam
'printer malfunction' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for jam that I've seen before include "Fruit preserve" , "problem" , "Conserve" , "awful traffic" , "Troublesome situation" .)
