How to change a fuse in the hp 2800 printer

The system will not totally power up. It shows the hp emblem on the little screen, but when you press the power button, nothing happens. is the fuse the problem. I think this happened when we had a power surge while printing and lost power. Mike

There are 2 fuses inside the power supply unit.

The hard part is getting to the power supply! The power supply is located at the left side of the printer and in the front (the opposite side of the cartridges).
You have to remove the side and top covers.
There are some hidden screws. One is under the button faceplate that you will also have to remove. The entire procedure is tricky especially without a service manual. Unfortunately I couldn’t locate a manual.
Caution always disconnect the power lines and allow some time for capacitors discharge before you attempt any repairs.
I hope you have some luck with yours !!

HOW DO I ACCESS ANDROID SYSTEM RECOVERY MENU?


1. When the phone is powered off, press and hold the Volume Up and the Volume Down keys both at the same time, then press and hold the Power key until a test screen that shows some available options appears, usually takes about 15-20 seconds. When that screen pops up you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights FACTORY RESET then press the Power key to select it.
2. Power the phone off all the way, press and hold the Volume Down key and press than release the Power key, still holding the volume down key for about 10-15 seconds. When you see some additional options pop up on the screen you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights the reset option; it usually says FACTORY RESET, then press the Power key to make the selection.

Hi

Did you check the connections in the carriage if there is little amount of ink on the contacts? if not then clean it well with a dump cloth and try to re-install the old printhead it will sure accept it. If not then the other way is to change system date of the printer first and then try again.

Hp 2800 printer will not boot after multiple attempts at cycling the power all that happens is the green light and scrolling dots on the display screen


In all likelyhood, a capacitor on the main pc board had blown, they problem caps are TEAPO 6.3v 680uf. Look at the caps and see if any of the tops of bulged up. If so, replace the caps (about .14 each). The caps control voltage to the actuators, without which, the printer's OS never gets past initialization.

Try This:
cold reset on the printer with only the power cable connected. By doing so, the printer settings will default to factory settings. Please note that after a cold reset the printer settings will default to factory settings and you may have to re-configure all the settings.

Press and hold the Return and Select buttons, then press Power button to turn on the printer.

The best way top get usage info is to print a Configuration page. It will show the print head health, ink levels and recent errors like paper jams and firmware errors.

With the printer on, press the (check mark) select button on the control panel, when "Information Menu" is highlighted, hit select again. Press the Down Arrow button until "Print Configuration Page" is highlighted, then hit the Select button.
