I have an HP Laserjet 8000 that when it prints the text feels like
brail, it is built up more so than a normal print and you can rub your
finger across it and feel the print. What piece is causing this, old
drum or fuser?? Printer is about 4 years old with never being serviced.

It certainly isn't the fuser because fusers do not apply toner to the paper,
they just fix the toner that is already there.
Likely cause is the toner cartridge but it could also be an electronic failure
(hopefully not). You can alter the print density in this printer from the
control panel, go to the print quality section and then print density, make
sure it is not set too high (3 is normal). Try different settings and see if it
makes a difference, if it does then the electronics appear to be OK.
I believe the toner cartridge is almost certainly the cause however.

Hmmn, that's a brand new toner and it has been doing it for a while.
I'll try the settings you mention. Thanks
 
If it happens with two cartridges then that rules out toner as the cause.
Does the problem occur with the internal test prints (from the printer control
panel)?
If so, and the print density is correctly set then I guess there is either a
high voltage problem or a failure of the engine control PCA.
Does the problem occur over the entire page or is there a pattern to the
problem on each page?
It is worth cleaning all of the contacts that are on the toner cartridge and
the ones in the printer that mate with them, especially the high voltage
contacts (these are at the right hand end of the cartridge as you remove it
from the printer), a clean dry cloth is sufficient.
Also cleaning the transfer charge roller may be worthwhile. This is the long
roller that sits immediately under the cartridge, you don't need to remove it
to clean it. These do not usually cause too much toner to be deposited on the
paper but easy to clean. Don't touch the roller with your fingers (to avoid
contaminating the roller), use a clean dry lintfree cloth, wipe it alaong the
roller and turn the roller as needed with the gear at the left end.
