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 Printhead crash, thus causing many media jam

failures to be reported as head crashes.

1 Di

d 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.

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.

Banding at variable extreme environmental conditions

Since the Accuracy Calibration has been done at normal environmental

conditions, printing in extreme environmental conditions will cause banding

because the advance of the Media Advance Roller does not correspond to

the same conditions that the calibration was done in. To solve the problem,

try the following:

Perform the Accuracy Calibration in the new environmental conditions (Refer

the U

ser’s Guide).

Worm marks on HP Coated media with light area fills

Light bands (S-shaped) in Paper axis direction where light area fills are

printed, causing unacceptable Image Quality defect.

 Print the Service Configuration Print and check if the level of Humidity is

very low (below 30%). Increasing humidity may help in reducing the

severity of the problem.

The media is causing the problem and NOT the Printer. Do

not attempt to try and replace Printer parts to solve this

problem.
