E4.03
Media Transportation
RAP W/Tag/MOD 17
(4/26/93)
The status code E4.03 is displayed when the
logic detects that the media is jammed in the
Fuser area of the Media Transport. As the
media moves through the Media Transport,
the image on the media
is
fused by the Fuser
Heat Roll. The media is held against the Heat
Roll by the Fabric Guide. The Stripper
Fingers assist in the removal of the media
from the Heat Roll. When the media is not
removed frdm the Heat Roll, the Stripper
Finger Jam Switch (S1) is
deactuated.
E 4 . 0 3 Indicates that the logic detected
that the media is jammed against a
Stripper Flnger causlng the Flnger
Assembly to move out of position.
When the Finger Assembly moves
out of position, the Stripper Finger
Jam Switch (S1) deactuates, causing
the Media Misstrip signal to go
LOW (L).
The Stripper Finger Jam Switch (S1)
is normally held actuated by the
Stripper Finger Assembly, as media
is driven through the Media
Transport. The Media Misstrip
signal remains HIGH (H) as media
is
successfully driven through the
Media Transport.
The problem may occur if there
i s
a damaged
Stripper Finger Assembly, the roll media
Is
not positioned correctly on the Media Roll
Support Tube or the lead edge of the media
is damaged.
