Mechanical problems, such as misdeeds and paper jams, are normally caused by the media being used in a printer rather then the printer mechanism. The following are typical problems.
Misdeeds
If a misdeed occurs, remove the paper from the paper feeder, and fan the paper so that sheets are not sticking together. Reload the paper ensuring that the curl is loaded as specified by the printer manufacturer.
Paper Jams
If a paper jam occurs, carefully follow the procedures in the laser printer user guide to remove the jammed paper. Pay particular attention to instructions which require the paper to be removed in a specific direction, as the paper may have loose toner on it which has not been fused and which may contaminate the printer mechanism. Paper may also be jammed between paper feed rollers or in the fuser rollers, attempting to pull paper in the wrong direction through these rollers will probably tear the paper
Lost Characters
If characters are occasionally missing from the text there is probably a communications error.
Check that the cable connecting the printer to the computer is correctly plugged in. Check the communications settings on the printer and the computer, ensuring that they match. Try using another communications cable. If a serial connection is being used, try setting the serial baud rate to a lower speed.
