Troubleshooting

Picture 2: O ring that seals primer with Print Head. 

4.

If you have tried to repair the primer then repeat from step 1 and check if the primer is working as 

expected. If it does not, check that the primers’ electrical cabling is correctly connected, (to confirm 

a failure of the primer you can swap the primer/printhead latch between both Printhead, to check if 

the issue is following the PH or is following the primer). 

Note that this process to grease is documented within the maintenance and troubleshooting guide, 

released on June 09 on the 

www.hp.com

, under L65500 manuals.

In case you suspect that one primer is failing, run the following test from diagnostic: 6.6.1 Force Prim-

ing Left, or 6.6.2 Force Priming Centre or 6.6.3 Force Priming Right).

In case of requirement of support from HP, here are the information to provide, in order to speed up the 

response time: 

The files (.xml and .tar.gz) from the HPretrivertool. 

Find where the air leakage is coming from: We have found 3 parts where we can have an air leakage: 

•

At the metal parts which presses the black rubber on every end of the spindle. (this metal part can 

show one or two Hex screws). 

•

The air valve (the place where the air gun is applied) 
•

and be through the part around the air valve 

•

or can be through the middle of the air valve 

•

The black rubber parts, the ones that are inflated.
