Troubleshooting

It is very important that the customer understands that the in cartridge has to be handled with care mainly 

when it is connected to the cartridge connector/printer.

Here are 3 situations which can create an failure on the ink pressure sensor and so cause an ink leak:

•

With the connector from the printer inserted, and letting the cartridge fail from a few centimeters 

down to the tray

•

With the connector from the printer inserted, in case the customer is trying to force the usage of the 

remaining ink, by pressuring manually on the cartridge box or on the cartridge bag (after having 

removed the carton): just a slight pressure applied on the ink bag can create an ink leakage.

•

In the case of ‘Out Of Ink’ is displayed for one of the cartridges and the operator retrieves the new 

supply from storage and brings it to the printer, but accidentally lets it fall on the neighboring ink 

cartridge. Then, the operator removes the empty cartridge, and inserts the new one on its tray. 

During this operation, the neighboring ink cartridge has received an overpressure and this can 

create a failure on the corresponding ink pressure sensor situated at the bottom of the cartridge.

The reason for the failures is because the ink pressure sensor is directly connected to the cartridge, there 

is no electrovalve in the middle protecting the pressure sensor, any variation of pressure on the ink bag/

cartridge is transferred immediately to the ink pressure sensor and this can cause an ink leakage.

•

The files (.xml and .tar.gz) from the HPretrivertool (please refer to the specific newsletter available on 

this tool). 

•

In case the HPretrivertool can not be run, at least the following files are mandatory: 
•

Supply0.log, … Supply5.log (total of 6 files). 

•

How to collect them: 
- Open an internet window, and type http://<ip of printer>/hp/device/3432/8828/tmp/ 

<ip of the printer, displayed on the small front panel, if you do not know it, from diagnostic, 

available within electronics menu -> IO information. 

- For each file, select it with the right click and do a file save as on a specific location on the 

PC. 

- Once all the files are transferred, just zip all together and send them to your HP support team.

Perform a do a hard cleaning. At the end of the cleaning, open the Printhead cleaner assembly and 

compare the results with the following pictures: 

This procedure must be performed with the ink cartridge disconnected, there is a real 

risk of damage to the ink pressure sensor and an ink leakage. NEVER PRESS ON THE BAG WHILE THE 

CONNECTOR IS INSERTED.
