How much RAM should I use in an HP LaserJet 4000 with JetDirect 610N?

I currently have an HP LaserJet 4000 with the JetDirect 610N network
adapter. It currently has 4MB of RAM and it is upgradeable to 100MB. I
wonder if I should upgrade it, and if so, should I max it out?

I looked for the RAM on eBay and some sellers sell 64MB sticks and they
say these are compatible with the 4000. In the HP site, it seems that
32MB sticks are the largest it will accept. Will the printer accept a
64MB stick and allow you to just use 32MB of it, or will it let you use
the full 64MB of RAM?

Another thing I noticed on eBay was a seller stating that you could
actually max out the 4000 with 160MB of RAM, instead of 100MB. Will the
printer accept the full 160MB of RAM and allow you to just use 100MB of
it, or will it let you use the full 160MB?

Btw, I am thinking about getting the duplexing piece. I will get either
the C4123A or the C8054A. Is there a difference between the two? The
C4123A is mentioned in the manual, while the other isn't. I have seen
several sites that state that the C8054 is compatible with the 4000,
4050, and the 4100.

I will mostly be printing text with row and column divisions and small
logos. I will also need to print pictures and diagrams sometimes.

Thanks for any help.
 
I don't have any specific answers to your questions, but based on
my experience over the last week, I recommend that you be cautious when
a vendor says "compatible". I've found many sources that claim their
memory is compatible with my Phaser 7750. However, the memory usually
is CAS latency 3, not CL2. So the "compatible" memory is slower than
the factory memory. The result will either be a slower printer or a
possibly unreliable printer. I'm not willing to accept either of these
choice.

The C4123A was the older duplexer, and AFAIK only worked with the
4000/4050. The C8054 is the replacement, and also works with the 4100.

Taz-

I recommend maxing-out the memory.

I've used HP LJ 4000 before, but never got into the works. From what you
say, I would guess that it has either 4 MB on the mother board and three
SIMM sockets, or 4 SIMM sockets with one occupied by a 4 MB strip. To get
to 100 MB, you would add 3 strips of 32 MB each. If 32 MB is the max
size, the most you could fit in would be 128 MB, of which only 100 MB
would be recognized.

Adding more memory than specified might work with the excess being
ignored. However, it is possible the extra memory's address space would
duplicate the address space of the printer's ROM, resulting in a conflict.

When I wanted to upgrade the memory in my HP 4600 LaserJet, none of the
big computer stores had memory strips as small as I needed. I ended up
finding a small locally-owned store with lots of older SIMMS. I got
exactly the memory I needed to max-out the printer for less than I would
have paid for larger SIMMS I didn't need, and I didn't have to fuss with
eBay.

If you can get the duplexer recommended for your model, that may be the
best option. Someone in a different thread mentioned two duplexers that
would both fit an older printer, but had differing numbers of teeth in the
gears. Better safe than sorry.
