2.4.5 Cleaning the Paper Stock Guide Rails
Occasionally, the 8500’s paper stock guide rails need to be cleared of jammed paper stock or paper residue.
The following steps involve first removing the entire print head/paper stock guide rail assembly to avoid
spilling the cleaning fluid Fedron on, and thus damaging, the daughter board or power supply. To clean the
rails, complete the following steps:
16 Lower the print head assembly, making sure to securely latch it back into position.
17 Lower the printer’s cover, plug the AC power cord into a power source, and turn on power to
the printer.
18 Reload paper stock.
Step Action
1 Power off the unit. Unplug the unit’s AC power cable from the power source.
2 Open the printer’s cover by pressing the cover release button.
3 After the cover pops open, lift the cover to the full upright position.
4 Remove the two screws holding the metal cover over wiring and circuitry for the print head.
