Troubleshooting
Cover sensors are not working
To resolve cover sensor problems, do the following:
1. Perform the Sensors Test
⇒ See page 173.
2. Check if the cable for the faulty sensor is not damaged and is connected correctly.
3. Replace the faulty Sensor.
The line sensor has problems detecting media
To resolve line sensor media detection problems, do the following:
1. Check the type of media that is being used since the Line sensor may have problems detecting trans-
parent media or some types of Non-HP media. Try loading white HP media in to the Printer and
check if the Line sensor detects it.
2. Excessive ink deposits on the Platen surface can fool the sensor by reflecting the light. Clean the
Center Platen.
3. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration ⇒ See page 162.
4. The Line Sensor is damaged or faulty. Replace the Line Sensor ⇒ See page 486.
The Cutter does not function
Under certain circumstances the cutter will not cut the media. This is mainly when the take-up reel is
enabled, but there are other circumstances when the cutter will not cut.
• If the settings for the RIP have disabled the Cutter, but the customer has set the Front Panel settings to
cut, the customer could expect it to cut at the end of the job.
• If the customer presses the ‘Form Feed and Cut’ option, but the Cutter is disabled on the Front Panel.
• If the substrate being printed on cannot be physically cut because it is too thick.
The customer can enable and disable the cutter from the Front Panel (but remember this will be overridden
by the RIP). To enable the cutter from the Front Panel; select the substrate icon, then Substrate handling
options>Enable /Disable.
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 detected 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.
NOTE: 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.
