The part you will receive includes a One Year Exchange Warranty.

It is verified to work without errors by me -- A HP Certified Technician trained to work on the HP DesignJet printers since 1995.

Different lot number part numbers reference the same part:


I've had service calls on several T120 with similar error codes. The last one was BA7E70E6. The 'B' codes harkens back to the day when I routinely saw this type of error on the old 1050c\ 1055cm models. I used to tell customers you have the 'error code of death'. In more technical terms, the Main PCA Board has a defective chip or routine call somewhere on it and needs to be replaced. Replacing the USB (CQ890-67023 CQ890-60251 CQ890-67097) has resolved the error for me.


If you have a 59.2:19 error . . .


Enter service mode and do a hard reset.

With the error on screen, try pressing the Power button continuously for 15 seconds.

The Support Menu screen should display

Press Support menu, > key, 3 times.

The printer is going to ask for the password.
The password is: 3746

Press OK

If it works, the printer will reboot and ask you to select language.

Please call me if you need additional support.

Thank You,
