Hp Designjet t520 paper jam error

HP Recommended
HP designjet t520
Microsoft Windows 7 (64-bit)

I am the tech guy at a middle school.  The school  purchased an HP Designjet T520 to do posters and such.  It was purchased about two years ago.  When I tried to get it running for the new school year it gives me this:

 

X Possible Media Jam

 

Possible Jam, printer cannot continue.  Remove jammed paper and review that cartridges and printhead are correctly installed. Press ok to continue.

 

There is no paper jam and no tiny slivers of paper at all.  I took out all the ink cartridges and the printhead carrige and I reinserted them.  I have tried hard resetting it by holding the power for 15 secords and going through the menu.  No matter what I try it still gives me that message.  

 

Any suggestions... help!!!!!

Hi

 

 

Please process the below info:

 

 - Clean the encoder strip with a lint free cloth damp with water

 - Make sure carriage belt is ok.

 - Make sure the roll is loaded correctly on the spindle

 - Make sure the spindle is installed correctly

 - Measure the paper and make sure is a supported size

 - You just clean the media detectors sensor which is stay with carriage unit. If problem will not solve please update the latest firmware.

 

Hope my suggestion is helpful.

Hi,

 

Beside my suggestion at above, this is the link that showed detailed and complete steps for troubleshoot action.

 

Possible Paper Jam Troubleshooting Steps

 

pls be noted that the model list for above troubleshooting manual doesn't include T520, which there may be some minor difference on part location, but you can follow the similar steps.

 

Hope it helps.

Hi,

 

The "X" Error is for the Carriage movement.

Remove the power cable > try to move the carriage to check if it moves freely, ( if locked on service station if may not move)

Ensure the Print head white locking lever is lowered and is not blocking the carriage path.

Genera check on the Carrige belt condition , clean the encoder strip with a damp cloth.

check if the carriage moves from the service station > moves to full width to left and then to right and the error pops up.

it could be the encoder strip or the carrige belt.

 

As a precaution: check for any physical obstruction to the extreme left and right of the plotter.

if the carriage is kept in the middle and powered on > check the carriage movement.

if the carriage jerks / moves for 5 - 10 mm and errors then the issue is with the carriage assy.

if the carriage moves completely - then the encoder / belt .

 

Hope this is helpful.
