T120 - Blue Screen with error code B87E7110

[TiffVH]

I'm getting a blue screen with the error message B87E7110.  I was told that it might be a problem with the main PCA of the printer.  Does anyone have any other insight on how to fix this or where to purchase a replacement PCA?  Thanks.

Hi,

Problem: Blue Screen Error B3320C36 for HP DesignJet T120/T520 Printer.

Please at first try isolating the printer, remove inks, printhead, connectivity cables, another power outlet and then turn the printer on.

Main reason for the Encrypted Chip, which is not orderable to HP. That's why need order whole main board.

If still problem persist, please replace the Main PCA and Encrypted Kit. That is the proper channel.

Main PCA for HP DesignJet T520 Printe (P/N: CQ890-67097 ) - 36"

Main PCA for HP DesignJet T520 Printe (P/N: CQ890-67023) - 24"

Main PCA for HP DesignJet T120 Printe (P/N: CQ891-67019)

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:

is there any way to check if the encrypted chip is defective 

[LucekKL]

all blue screens on t120 are because of that chip

Hi,

Isolate the printer, remove ink cartridge, printhead and paper

Try another power cable and power outlet

If the issue persist use the CQ890-67105 USB New Module with F/W SV

Good news, that's a lot cheaper than the Main PCA

Thanks to all for your help.  Time was of the essence on this one, so we just ended up purchasing a new T120.

If you still have the T120, you have now a less expensive option to repair it 🙂

what if the screen is a green color and not so much blue, code B320 D660, HP say its the main board, what do you say about the difference in color, is it important or not

[rasheddul]

Hi,
Different colour isn't matter for this model. You just check my information if it was match with provided error. Then you may take the decision what can you do.

Thanks/ Rashed

ok - then the error code on the green screen is B320D660. is this going to fix the problem - if the usb card is renewed
