Most problems you may encounter while operating your printer have simple solutions.
You can also use the self test to determine whether the printer or the computer is causing the problem. See Printing a Self Test for instructions on printing a self test.
To pinpoint communication problems, experienced users may want to use the printer’s hex dump mode, described on Printing a Hex Dump.
To clear a paper jam, see Clearing a Paper Jam.
