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
Re: how to change a fuse in the hp 2800 printer, power up...
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 !!

There are no end of problems with HP printer driver software. I've had them too. The most likely success will come from completely UNINSTALLING the present HP printer software (ALL OF IT) and reinstalling the MOST CURRENT PRINTER DRIVER for your computer operating system. You download that driver from hp.com by inserting your model number an following the screen instructions. There is a companion PRINTER DOCTOR tool from HP that you should also download just in case you continue to have a problem after you install the new driver. I can't stress to much how important it is to completely remove all traces of the HP software from your computer first before you reinstall using the latest driver. Failure to do so will cause you continued problems.
Also, if you want to minimize other software issues, after you've downloaded the most recent driver, REMOVE your Antivirus Program if you are using one. I found that there were conflicts caused by Kaspersky AV firewall settings that HP software did not over come. I reinstalled Kaspersky AV after the HP software install and everything worked fine then. The necessity of this step seems to be computer-dependent. I have 3 pcs, all running Win10 Home and only ONE of them required this extreme step in order to get the software to function completely ok.
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.
There is no CMOS battery in this printer. The instruction manual indicates the only way to reset the printer is to power it off, unplug it, and let it rest for 30 seconds before reconnecting power and turning it back on.
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
Press and hold the Return and Select buttons, then press Power button to turn on the printer.
Check if the cartridges is not expired if it is change the date on your system and then try to print if it works, change the date prior to every print of jus do not power off the printer hope that help.
