I just bought a second user HP Laser Jet 4, the page count is 348370 Is this
a lot for this printer?
I bought one of those new for my business in 1994, give or take a
year. In 1996 I sold the business, including the printer. The buyers
of the business are friends and I visit often. The printer currently
has 1.2 million copies on it, and still works flawlessly.
A couple months ago the secretary mentioned that she was running out
of toner. I got four new reman carts for her for $38 plus $6 shipping
on eBay. When they arrived they turned out to be Verbatim, an
excellent brand of remanufactured cartridge. That's also the best
place to get other parts.
You do have to install maintenance kits every couple hundred thousand
copies. But basically, these machines will run forever. HP sold
bazillions of this model, so there will be drivers for new versions of
operating systems for a very long time.
The only caveat I have for you is to leave it turned off unless you're
going to use it. Leaving it turned on will eventually degrade the LCD
in the control panel. You can get replacement LCDs on eBay for $15-20,
but as long as yours is still working fine leaving the machine turned
off when not in use will extend the life of the LCD.
