Paper path transport components
In order for an image to be printed, the media has to be moved from an input source (such as a tray) into the
printer and eventually exit into an output source.
The most important component in this process is this media itself. Old, damaged, or out-of-specification media
can and will cause feed and transport problems. If you encounter problems, you should always check the media
first
“Media guidelines” on page 1-13
. In addition, it is always good practice to check the printer and driver
settings to see if the media being used matches the user’s settings. It is not uncommon to find a user printing on
cardstock with the printer programmed to print on a plain paper setting.
The printer’s feed and transport components can fail and cause paper jams or other feed and transport
problems. These components should be examined for damage or wear and replaced if necessary.
Below is a summary of the paper path, and transport components.
Paper path Information
The MFP has a simple “C” shaped paper path. The paper paths are shown in red. Paper is fed from the bottom
of the printer from the paper tray, or manual feed, and travels upward through the front cover.
There is a duplex unit on this MFP. The duplex unit is built into the front cover and drawer 1. Duplexing is
described later.
