My Hp 1020 printer is printing full black pages.....

i think your installer is wrong you need to download the best drivers
i hope i can help you

toner has been faulty. pls replace it.

it is the problem humadity or laser mirror is dirt clean it and then solve your problem

you shuld disable the " print the event log " in your driver in control panel

1: try another toner cartridge (or possibly pull the seal from the side of the cartridge you have just installed)

2: If it's not the cartridge causing the problem take it back - it has 1 year warranty.

Black is used on all prints. Did you pull the tape on the new cartridge?

1- black lines are from the drum: it has burnt out on that particular spot and rotates

2- the white horizontal gap space if it is not you skipping space is also from the drum

3-the white Vertical is most likely from the developper (unit that has the toner and is against the drum, look at the roller it should be solid black, maybe there is something on it : hair paper etc....

Is the black cartridge full?

First, you need to try update the latest microsoft office patch file from microsoft or you can open the MS Word, go to "HELP" menu select the update MS Word or related. Try the latest patch file first. You also can try windows update and select custom update, see their list have this problem solution or not. Second, you need to go to HP website download latest driver for LJ1020 and suitable use on Vista. Lastly, if still not solve the problem, you need this problem/issue to microsoft, ask their solutions. Kent

in my printer the resistor R348 on the motherboard printer was broken. The value that must have is 10 ohms. I have changed and the printer has resumed work.
