Troubleshooting
Media Jams/Printhead Crashes |
|
|
NOTES: If using HP Coated
Media when problem occurred, please also refer to Printhead
Crashes/Smears on High Density Prints Using Coated Media.
The failure modes "media jam" and "head crash"
are grouped together because in many cases a media jam causes the
media to lift up into the carriage path and cause a head crash,
thus causing many media jam failures to be reported as head crashes.

1. Did the media
jam occur when loading media?
If the client has had media jams, it is common for pieces of media
to get stuck in the media path. Clear the media path.
NOTES: When clearing a media jam, sometimes media is stuck
in the paper path. To clear this, you must lift the media lever
and insert thicker media into the paper path to push out the media
that is still stuck there.
2. Is the customer using non-HP media?
The use of non-HP media can easily be the cause of media jams and
head crashes (especially head crashes because HP media is specially
formulated to avoid cockle, one of the primary causes of head crashes).
If the media is not HP approved, advise the customer to use HP media
and check to see if the problem is now solved.
3. The Carriage is at the incorrect height in
relation to the Center Platen. Adjust the carriage to the correct
height (See Carriage
Height Calibration) and try to load the media again.
4. Check that the Vacuum Fans work correctly (Refer
to Problems with Vacuum).
