HP Business Inkjet 2800 Printer is displaying *********** in the panel window. It does not go past and does not print.

Discovered bad capacitor on pc board 680uf 6.3 volts. Look for one with the top expanded up. I had the same issue, one $.14 caps later, all is well.

How to change a fuse in the hp 2800 printer, power up problems

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 !!

Hp business inkjet 2800 will not print cyan although have replaced cartridge and run all onboard diagnostics. hp troubleshoot shows no problem yet printer will not print

You say you replaced the cartridge but did you replace the print head. If you fully lift the cartridge cover you will see a row of print heads. The Cyan print head is C4811A. Try replacing this.


If you feel lucky you can run the print head cleaner diagnostics. The print head may simply be dirty or clogged.
