[ Edited ]
Product Name: HP DesignJet T120

When the network device blinks twice
white screen and then a second HP logo appears,
and then blue color with an error in this servismanuale no error,
there is also a blue screen but with different numbers and letters,
write-treatment -vykp. incl. EC but does not help.
The power supply produces its 32,
the control points in the "mamma" voltage match
stated, however, the LED on the board with the appearance of blue
the screen flashes, which did not exist (are smooth).
No movement of the carriage, what the general perturbations
not happening. Includes ink cartridges and without,
without heads, too, tried,
disconnect all sensors and sliders left only monitor
and the On button. Battery and dragged me,
and stood for hours without batteries. On button responds:
if you just click -perezagruzhaetsya,
if you hold 5-6 seconds and then -vyklyuchaetsya.
We ate out of him Bluetooth On button does not react,
however, and it does not fall into the error and then not loaded.

At first try to follow the below steps and get it fix by :

- Connecting the printer to another outlet

- Repacing the power cable

- Replacing the Main PCA (If you have replace Main PCA, it will solved the issue.)


Also try to Isolate the printer by removing any connectivity cables, printhead


Try removing the ink cartridges, printhead, paper, replacing the power cable and another power outlet. If you still have the problem, please replace the Main PCA (P/N: CQ890-67097)




Part Store:



N.B: Part No. CQ890-67081 is an older revision.


Main PCA - T120: P/N: CQ891-67013

Main PCA - T520: CQ890-67023 


It is my understanding that the new Main PCA should come with the USB with the FW. Make sure it is there before installing the new main PCA.

If problems with the FW, will not recommend you to use the old USB with the firmware again.


If not covered under warranty you may replace Encrypted chip which is failed on the mainboard inside the printer you can buy it on ebay/other's source:
