QUESTION pagecounts

[Guest]

Archived from groups: comp.periphs.printers (More info?)

I hear a lot the word "pagecount" is this something like the mileage on a
car? a number that stays there when powered off, when toner changed, etc?
does it only apply to certain printers? if so, would the hp lj 1100 be one
of them? and if so, would a 7000 pagecount be considered low, moderate or
high?

regards.

Page counts are just what they say they are. The number of pages printed.
I've not had any laser's that didn't give a page count and even my Canon
inkjets give a page count. 7000 isn't even a case and a half of paper. I
haven't had an HP 1100, but I'm sure it would give you that info from the
configuration printout.

thank you.
I just wasn't aware of what they are.

so I was correct then, they are a count number of some sort, showing up on
some display when you turn on the printer, and this number cannot be erased
modified etc. everytime a page prints, it increases... stored on some sort
of internal memory, so its not erased while printer is off line. did I get
it right pretty much?

thanks again.

Pretty much. Often they don't get displayed on startup, but you can ask
the printer to print the pagecount. (on my HP LJ4+, it's on the test
page).

Some printer/scanner combinations will give two counts - scans and
prints.

The page count is useful for seeing how long consumables last, seeing
when a service is due, and to see how much a used printer is worth!

good.
thank you.

yes it definitely is useful. right now, to me the use of it is much more in
the sense of the use of a car mileage when you buy it. but I understand the
other uses as well.

It's harder to tell on a printer, esp since it's part of the normal
operation to reset the page count when you replace key parts... for
example on an inkjet it's common to replace the waste bin aka the
diaper.

7000 on a lj1100 for example (Canon LBP-22X print engine IIRC)... is
equal to two large toner replacements, or three small toner
replacements. It also represents 14 packs of paper.

To best judge if this is alot or a little is to look at the lifespan of
other parts in the printer such as the fuser, the part that heats the
paper and affixes the toner to it. I know it's rg5-4589-000 but I
have no clue what life is on that part. A fuser's life can be anywhere
from the 10,000 range to the 100,000 range depending on the printer and
model... though I've never actually replaced one in my life. Given
it's a $70-$120 part i'm sure it's life is lowish esp since the fuser
was the foil type and not a tough teflon roll. I would guess 10,000p
is a good number to check the condition of the rollers, if good check
again at 20,000p.

Just as with a car mileage, it can sometimes be faked...!

I find it useful to know how long a toner cartridge has lasted, and how
long to go. I have a sticker inside the lid where I record toner
changes...

I See. so it can be faked.
like everything else today I suppose!

how do I tell or suspect whether its been faked? I think I could tell on a
car...but a printer?

I think this is a cheap and cheerful laser but even so 7000 isnt much, I
would guess its probably on its third toner cartridge.

Not true on the average laser printer; it's supposed to be
non-resettable.

For example, on the LaserJet 4 it can be reset by an engineer - and that
is done if the engineer changes the board with the counter NVRAM on it.
He is supposed to set the new board to have the same count as the old
one.

7000 pages is quite low, I have seen a LJ1100 with nearly 100,000 pages but
that is rare.
If the print quality is good and it does not exhibit any feeding problems
(multiple feed, failing to feed or skewed feed) then it is probably a good
printer. They are very reliable.
The only way to reset the page count on a LJ1100 is to replace the main logic
board so far as I know.

Actually you said "on the LaserJet 4 it can be reset by an engineer -
and that
is done if the engineer changes the board with the counter NVRAM on
it".

>From experence i've met a few LJ4s that have been rebult where the
rebuilder has reset the counter to zero after replacing all the rollers
and some key parts... and explained that after a major rebuild it was a
good idea to set it to zero so he and others know how many prints are
on the new parts. I imagine it would be unscrupulous if they had set
it to a value under that zero... and sold them as rebuilt.

You assume that the "engineer" in question has the offical service
manual. I wouldn't call them "engineers" my self but rather mechanics.


I have seen rebuilt HP printers... or ones that have gone through major
service get their counters reset. Some cases this is logged... honest
joes who are depending on the printer's counter to see how much has
been printied out of their shop. Is this in varanace with the offical
instructions? Very bloody likely... but never the less this is done
esp in cases where service is under warranty for a specific number of
pages. Other cases this is not logged.

Not to speak of average joe users who encounter a problem on their
printer that says "need service now" who rather than getting service
will just reset the counters so the printer thinks it's new and
continue printing till the next time.

A good rule of thumb... always bet on stupid... or rather always bet on
someone doing things their own way in total varanace with the offical
instructions.

It's completely at variance with the instructions in the service manual.
A proper maintenance log will give the same information. What is lost
with your engineer's method is the life of the parts that are not
replaced...!

Would you compromise and call them technicians? They cannot do their job well
without a good knowledge of several operating systems, networking and of course
the eccentricities of badly written drivers as well as a thorough knowledge of
maybe several dozen different printers. Just a thought.
But with respect to page counters.....several older and/or low end monochrome
laser printers don't have a counter. Some have one counter that may or may not
be resettable without replacing a board. And some have two or more counters
related to total pages printed and pages since the last maintenance kit was
fitted, toner/drum life etc. Colour lasers on the other hand may have more than
a dozen counters all of which are often resettable if you have the codes.
Clearly a technician has a responsibility to reset counters appropriately and
whilst I am sure there are some that don't it really is not in their interest
to artificially reduce page counts (it may be in their interest to increase
them if they are unscrupulous!).
Bit of a moot point really....The most important counter is total page count
since "birth" since this is a measure of the printers overall usage hence the
requirement to enter this count into the memory of the printer if the
appropriate electronics are replaced, unfortunately this is not always possible
if the original page count cannot retreived after an electronic failure, hence
the advisability of the user to keep a log especially with high throughput
printers.

On an HP4 or 5 at least, you can set the pagecount to be anything you
want from the front panel if you know the magic combination of
keypresses to enter "service mode". It's in the service manual, which
you can find at http://www.fixyourownprinter.com/reference/manuals.
I don't think this is a secret from anyone unscrupulous enough to want
to do it, so be aware it's no guarantee.

Actually, no, it's not what you stated at all.

You said: engineer required, only can be done during board exchange

He said: User accessible with service code, done by front panel presses.

That's a bit like equating hiring a mechanic to replace a faulty
transmission so your car will go, with turning the correct ignition key
on your car to start it and drive away.

No, I didn't. Here, cut and pasted from my post:

"For example, on the LaserJet 4 it can be reset by an engineer - and
that
is done if the engineer changes the board with the counter NVRAM on it.
"

At no point did I say "engineer required". I just said it can be reset
by an engineer. As long as one has the information in the service
manual, anyone CAN do it.

And I did not say "only can be done during board exchange". I said that
the value is reset by the engineer when the board is changed - that is
to carry over the value from the old board to the new, so that the page
count is preserved.

> He said: User accessible with service code, done by front panel presses.

Yes, it is done with front panel presses. I didn't mention the precise
mechanism, that's all. It's usually only done by an engineer, of course
- or a dishonest user - or an honest user changing the formatter board.

> Your lack of comprehension is astounding. I give up.

His comprehension is perfectly fine. You see someone like me who
doesn't actually know the button presses to the LJ 4 reading ""Not true
on the average laser printer; it's supposed to be non-resettable" and
"that is done if the engineer changes the board with the counter NVRAM
on it" is going to assume you mean a difficult task, like yanking off
the NVRAM chip... and either taking it to a machine that can reprogram
the NVRAM or taking the time cutting the battery, reconnecting the
trace and popping it back in the printer so to convenience the printer
the NVRAM needs to be reset and ask for values to put in it. Having to
retrofit batteries on NVRAM chips in a pinch I can tell you for a fact
dealing with these things are a huge pain in the tookus. I'm sure this
is in total varanace of any offical procedure, but what can you do that
doesn't involve ordering parts and waiting.

I wonder though if a board is bad or if a printer is not printing how
do you get these numbers to transfer to a new board without extracting
the NVRAM chip, and if you can extract it and it's good why not just
use it in the new board rather than deal with manual entry. Perhaps
my lack of comprehension is astounding as well... but i'm seeing the LJ
4 as being just old enough for the batteries on the NVRAM chips to
start to fail.

I don't honestly know why some rebuilt printers are reset to zero, only
that i've met many, as well as some shops who reset the page count to
make life easier for them doing maintance... as in reset to zero as
soon as the part with the longest duty cycle is replaced. I also know
that many go through PC recycling... as in they are dropped off without
their histories. I gotta say under that scenero... a very common
one... there is no way to establish the history, not to speak of users
who are not so attentive as your self. Rule of thumb... always bet on
lazy.

I honestly don't know if the LJ 4 has their NVRAM chip soldered on or
not. The batteries on them are not officaly end user replaceable..
they are embeaded somewhere between the dram and a hard plastic shell.
The easy way to deal with failed batteries on NVRAM is to get another
chip. The hard way is to scrape away with an exacto knife and trace
out where the battery meets the chip and find the pads that attach to
the dram. You go the hard way if the equipment in question won't
operate without valid data in the NVRAM and can't do without it for a
mailorder part. I've never seen the procedure in any service manual
but I have met many batteries attached to the back of NVRAM chips with
velcro and thought "cool, won't have to touch this till 2150". While I
don't know the particulars of the LJ 4 nor what type of NVRAM is
used... in general the useful lifespan is 10 to 20 years. You can't
really change the battery, you can only hope to disconnect the old one
and jerry-rig on a new one. Unless there are other forms of NV that
i'm not aware of... it's just ram with a battery backup that becomes
just as volitile as ordinary ram when the supply of power gives out.

I've only had to swap out a board for my stylewriter II NT once... and
as I disabled the "print page count on startup" I had no clue what the
pagecount was. Come to think about it... I had no idea how to set the
pagecount. Not that I couldn't find out... I had no idea what the
pagecount was. When I gave away the printer... the next chap was
interested in the page count, but I had to say no idea... blew a board,
diabled hard copy upon startup. They were more interested in my
knowelege of obscure propriority apple commands to do this than the
pagecount, either that or testing my honesty... either way what could I
do? This is not uncommon for anyone who needed a main board
replacement. Can't get the page count board broken.

Higher than high-school, hince the name higher degree. Generally
speaking people mean BA or above when saying higher degree.

Generally speaking engineers design and build... technicians and
mechanics repair and maintain. I know there are exceptions... like an
engineer on a train (engine operator), custodial engineers, power plant
operators and engineers (engine operator). I would never call a
person who's only qualifications in printers is reading the service
manual an engineer. Service manuals are far too limited and don't
really list anything that requires specalized knowledge but rather list
button presses and large serviceable parts that can be replaced.
Printer techs don't typicaly don't even have repair manuals.

Resetting the pagecount doesn't require a degree or knowelege of
electronic nor mechanical engineering, nor a university education.
They hardly require specalized knowelge of printers. They are for
printer technicians so someone not very well paid could make a
judgement whether to replace a part or send to the factory.

Could be... can't say I ever remember seeing a traditional battery on a
PS/2. Can't think of why you'd need one really except for the clock...
unless the data for MCA cards was stored on the NVRAM and not the HD.
I don't know of any PS/2s still in service except a few oddball ones
that have 3270 terminal adapters onboard. If this data is on the
NVRAM, well lots of luck to them looking for the reference disk or
whatever IBM called the associated data file required to configure MCA
cards. IBM at one point had all this data on FTP... but as they
ditched lifetime free tech support I imagine they probally ditched this
data as well.

Frankly I know jack about the PS/2 even though i'm quoted on somesite
as having contibuted some useful information on a website somewhere....
hell if I know anything useful about the PS/2.

Good thing I didn't say it used NVRAM then i'd feel foolish. But on
the other hand I know for a fact that the HP LJ II error code 68 "NVRAM
ERROR". But I honestly don't know how the canon sx based printers were
different... as in I wouldn't know if the NVram that a HP LJ II would
complain about was on the main system board or part of the print
engine.

Or you could be telling me that the page count on the LW NT was not
stored on the system board, in which case I guess i'm a dumb ass for
even thinking I lost that information when I changed system boards.
The fact that the page printed on start up had a big bold friendly
postscript P on it along with lots of data like the printers name, in
my case Oscar and the page count lead me to believe that this was
system board specific information. But given I've never read a service
manual for these printers, nor a parts manual nor a repair manual I
have no idea where the NVram was on the LJ II nor if the LW NT would
have the same thing.

I can say with all honesty I have no idea what method the LW NT used to
keep track of it's page count.

But needless to say even if I didn't loose this information... the
NVRAM in a old printers may have dead batteries, and no possible way to
get a real page count. A very real situation even if I have no idea
where this data was stored on a LW NT. A legit reason for the counter
to be wrong are cases there the system board failed and the person
replacing it has no clue what the pagecount is.

I'd call this "extreme backpedaling" to go with the your extreme ironing.

Let's look at the WHOLE posting, shall we?

Not true on the average laser printer; it's supposed to be
non-resettable.

For example, on the LaserJet 4 it can be reset by an engineer - and that
is done if the engineer changes the board with the counter NVRAM on it.
He is supposed to set the new board to have the same count as the old
one.

==============
See how you try to refute the ease in "faking" or resetting page count?
See how you state "Not true on the average laser printer; it's
supposed to be non-resettable."

You and the folks in Orwell's 1984 from the Ministry of Truth would get
along well. Too bad posts leave a history behind.

This isn't a big issue, but it really annoys me when someone, even after
being caught giving out misleading information tries to defend
themselves through selective quoting.

It really would have been much easier (and more correct) to just admit
you made an error, especially after admonishing someone else who
actually pretty much had it correct.
