look for a small sensor on you right hand side. it tell the m/c if it is open or close. it migit be stuck.

There is most likely a small piece of paper in the rollers take out Tonor and any parts that will come out with out having to use any tools. then spray with a can of air in all the rollers.

Paper Tray Lift error code. Check and reload all the paper in all the trays. Power off then on to reset. If this does not solve the code then pull out all paper trays. Reset machine leaving alll trays OPEN. Close the trays 1 at a time waiting 30 seconds between each tray closing. If the code comes back after closing a tray then that will tell you which tray has the problem. You can leave that tray open so you can use the machine and also you can check that tray more closely.

i have a pixma ip4300 i keep getting the error number 1250 "paper output try is closed" but infact its is open i have tried opening and closing and restarting and everything else i can think of. any ideas of what to do?

On the control panel there should be a button that either says paper select or looks like a bucket with lines in press this and the machine will change paper trays.

Thanks J
