Anyone with LaserJet 4000 and 4050's and similar printers can buy a Maintenance Kit
from
www.printerworks.com and put it in yourself...
It replaces the rubber components and the fuser, so you can give your wonderful workhorse
of a Laser printer, a little TLC.
I recommend it every 200,000 pages (as does HP).
The kits come with FULL instructions and anyone on this list can handle it...
There are similar kits for the Laserjet 4, 5 and 6, 2000, etc...

Agreed. Putting in a new toner cartridge always fixed it. Actually
I'm impressed with how much of a solid workhorse my HP LaserJet 4000N
has been. I'm a big of a print pig and I bought the cheapest
duplexing laser printer I could get almost 10 years ago. I have put
at least 10 boxes (not reams, but boxes of reams :-) of paper through
this thing and probably 5-10 toner cartridges and it has never broken
down.
