Re: laserjet 4000 error 22

Ralph, I operate my LaserJet 4000-family printer and set up those of my clients
to be networked rather than direct connected via parallel or serial. All of
them have at least 64MB of printer memory. But I have a VERY strong suspicion
that the messages would go away if you added memory to the printer. LJ4000
memory is very inexpensive these days. In particular, browser web pages require
a lot of memory to print successfully.

Other things you might try to deal with the problem:

Print with PCL rather than PostScript, or vice versa. I find PostScript to be
far better, mostly in handling Adobe PDFs.

I'm not sure if the LJ4000 PCL driver supports lower dots per inch than the
standard 1200dpi. If so, try printing the same pages at 300 or 600dpi. If
not, the LJ4000 PCL is upward compatible with the older printers, so installing
the LaserJet 4 or LaserJet 5 PCL driver would give you this option. If the
problem disappears at lower dpi, this confirms that the printer needs more
memory... Ben Myers

If you're printing the same jobs it should still work. Even if you
didn't have enough memory, it shouldn't have given that type of error.
Something changed, and it changed in a way that affected both parallel
and serial ports. Formatter problem, maybe, but it doesn't sound like
RAM. Unless the 4000 formatter doesn't have onboard RAM and a DIMM came
loose.

Too bad that the memory upgrade did not fix the problem. In addition to an
LJ4000 formatter board, be on the lookout for a whole complete and functional
LJ4000. Here in New England surplus ones are going for cheap. Got one for $20
a couple of weeks ago, only 70K or 80K pages printed, and EIO network card
included. Phased out by a local city government that apparently has some money.
