Printer Memory SIMMs,
Memory Types, Presence Detect Pads
What are SIMMs?
Many HP printers take 72-pin
SIMMs ("PS/2" SIMMs).
What does that mean?
This depends on the kind of printer
you have. Some need SIMMs with parity, some can take SIMMs with
or without parity (SIMMs w/o parity are a lot cheaper).
HP LaserJet IIISi, 4(M), 4Si(MX),
DJ 1200C(/PS), PJ XL300(/PS), DnJ A/B, DnJ 200/220 and DnJ 600
printers:
- The SIMM needs parity. Real
parity, not "fake" (computed) parity.
- The SIMM needs to be FPM,
70ns or faster. EDO memory will work in some printers,
but not all.
- The Presence Detect pads need
to be connected correctly.
- N.B.:
HP's part numbers for parity SIMMs are
C2065A
and C2066A
(4MB and 8MB respectively).
Almost all other HP models that
take SIMM:
- The SIMM does not
need parity.
- The SIMM needs to be FPM,
70ns or faster. EDO memory will work in some printers,
but not all.
- The Presence Detect pads need
to be connected correctly.
- N.B.:
HP's part numbers for non-parity SIMMs are
C3132A ,
C3133A and C3146A (4MB, 8MB and
16MB respectively). There seem to be several part numbers
for 32MB SIMM, I have seen D2298A , D3578A
and KTH-NPVEC/32 .
Memory
types?
FPM stands for "Fast Page
Memory". This is an old memory type, usually found at 70ns
or 80ns. Anything 60ns or faster stands a good chance of being
EDO, though there is 60ns FPM memory. You cannot tell FPM and
EDO memory apart by just looking at the module; though you can
look up the part number of the memory chips used and see whether
they are FPM or EDO memory.
To tell memory with parity apart
from memory without parity, simply count the number of memory
chips on the module. If it has 9 or 18 memory chips, all alike,
it has parity. If it has 4 or 8 or 16 memory chips, all alike,
it does not have parity.
If your module has 8/16 (unlikely to be 4) memory chips and
then another 1/2 chips that are not memory (but probably "in
line" with the memory chips, like this: MMMMcMMMM), then
it most likely has computed parity rather than real parity and
will not work in a printer that needs parity.
What looks like a parity module might also be ECC, though; so
be sure what you are getting before you get it.
Regarding EDO SIMMs: Whether
this works depends on your printer model. Seriously though,
we have had reports of successful use, and reports of unsuccessful
use.
The memory controller has to support EDO if there is to be any
chance of it working. With older printer models, that is probably
not the case.
Mixing FPM and EDO is discouraged, because it is not stable
at what was considered high memory access speed in those days.
However, since HP says "80ns or slower", we do not
necessarily see a problem in using EDO, as long as it works:
Even though the built-in memory will be FPM, and thus you are
mixing.
ECC memory is error-correcting
memory and will never work in a HP printer, though it will physically
fit.
Regarding speed: 70ns or faster
means you can take a 60ns SIMM, encode it as 70ns, and it will
work. We have successfully done this. HP actually quotes 80ns,
or "80ns or slower", but we like to be very conservative
about this kind of thing. SIMMs you buy nowadays will be 60ns,
anyway.
Presence Detect
pads?
Right. Pads (or pins, if you
so will) 67 to 70 on a 72-pin SIMM encode the size and speed
of that SIMM. Each of them can either be open or connected to
GND (ground). Look at a SIMM you took out of your PC. Chances
are you will see traces running from pads 67 to 70 to empty
points where a solder blob or SMD resistor would fit. If the
traces run to actual solder blobs or zero ohm SMD resistors,
then the SIMM has been encoded already ... it just remains to
be found out whether it has been encoded correctly.
PC clones, as a rule, do not
use the Presence Detect pads on a SIMM. That's why the pads
are (usually) left unsoldered. Furthermore, there is no standard
for the encoding of these pads. IBM has their own way, as does
HP, as does Dell, as do others.
So the printer
recognizes memory just by the pattern on these pads?
Exactly. If all four pads are
open (no solder blobs, no resistors), then the printer will
not "see" the extra RAM ... it's as if you never put
that SIMM in there. Once you put some solder over the right
points on the SIMM, you have magically transformed a $39 SIMM
into a $150+ HP printer memory expansion.
Test of Hewlett Packard
LaserJet 1100 series printers with added RAM memory show these
dramatic performance improvements with spreadsheets, slide sets,
desktop publishing, and web printing:
- Adding 4MB of
DRAM for a total of 6 MB reduces output times by 30 to 80
percent
- Adding 10MB of
DRAM for a total of 12MB virtually ensures no "memory
out" errors
Hewlett Packard LaserJet
2100 series printers require 20 MB total to print multi page
1200 dpi documents with comparable performance 600 dpi documents.
Examples using 20 MB:
- Output time reduced
by 66% with a 10-page slide set
- Output time reduced
by 33% with a 5-page report
- Output time reduced
by 66% with a 10-page HTML file

Monochrome Printing |
Tests using Hewlett
Packard LaserJet 4000, 5000, and 8000 series printers show a
range of performance improvements when base RAM is supplemented.
Users should consider adding RAM if they frequently print the
following:
- Multiple-copy
slide sets - print time reduced more than 50% by upgrading
to 36 MB
- Web-based HTML
files- print times reduced by 30% by upgrading to 20 MB
- PDF files - print
times reduced by 50% and errors avoided by upgrading to 24
MB
- Multi page general
office documents - print times reduced by more than 50% by
upgrading to 20 MB
RAM is especially
critical to reducing print times of color files. Tests
of Hewlett Packard Color LaserJet 4500 and 8500 series printers
showed that increased RAM would improve performance in these
categories:
- General Office
- print-time reduction is 30% and errors is eliminated with
48 MB
- Color Presentations
- Print-time reduction is 40% with a total of 64 MB; with
two-sided documents, an additional 16% performance improvement
is achieved with 96 MB
- Graphics-Rich
Files - when testing vector drawings and TIFF images, print
times for large 8 by 10 inch images decrease by 24% with a
total of 56 MB
- Desktop Publishing
- print-time reduction is 30% is achieved with a total of
96 MB
