Reducing the Frequency of Paper Jams
If paper jams occur frequently, even though there is no apparent problem with the
machine, either one of the following two reasons may be the cause. Follow the
instructions described below to reduce the frequency of paper jams.
■ There are torn pieces of paper left inside the machine.
Pulling jammed paper out of the machine by force may leave parts of the paper torn
inside, leading to frequent paper jams. If paper tears while you are trying to remove
jammed paper from the machine, make sure that you remove all torn pieces.
■ The paper-size detecting lever is set incorrectly.
Make sure that the paper-size detecting lever located on the left side of a paper drawer
matches the size of the paper loaded in the paper drawer. If the paper-size detecting lever
is set incorrectly, paper jams may occur more frequently. (See "Adjusting a Paper Drawer
to Hold a Different Paper Size," on p. 7-7.)
