Troubleshooting Media Jams/Printhead Crashes
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?
D 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.
2 Is the customer using non-HP media?
D 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 now solved.
