Media Path Considerations
Use a cleaning swab to remove debris, dust or crust that has built-up on the holders, guides and
media path surfaces.
1.
Use the alcohol in the cleaning swab to soak the debris to break up the adhesive.
2.
Wipe the ridges to remove accumulated debris.
3.
Wipe the inside edges of both edge guides to remove any built-up residue.
4.
Wait one minute before closing the printer.
Discard the cleaning swab after use.
