Well, thank you for all your suggestions.
We found most of the printers in each office floors are not used frequently
at all.
In typical case, these color printers are used, say two or three times a
month to print color charts for meetings. Most printing are black/white
re-directed to the main laser printers. For now, we just remove the 3e black
cartridges. Yes, its is drying out. Any suggestion for our office staff to
deal with this?
Thank you.
Removing the 3e black is the wrong thing to do. A cartridge is like
$12-$15. A printhead is $50 to $80. The HIGHEST waste you should
experience is 1 cartridge per year, actually 1/2 cartridge IIRC. Even
taking color into account, that's equal to 1/2 a black ($6-$7) and 2
colors ($20-$26). This is still less than the value of a print
head.
That's powering up the printer once every two weeks, and not using it
at all in between. Using it more, or less, and the printer will not
waste as much ink, or rather it will waste a similar amount less
often.
[how much are you printing]
(1) Turn off the printer.
(2) Press and hold the RESUME button, then press and hold the POWER
button.
(3) Release the RESUME button, Next press and release the RESUME
button two(2) more times in succession. Note: you are still holding
the POWER button). The printer's carriage will "reset" or move
momentarily. If the above was properly performed the printer will
enter the "Service Mode".
(4) Press the RESUME button 1 time, then press power. The printer
will spew out a diagnostic page siting how many pages the unit has
printed on various papers.
(5) Press POWER to resume normal operation.
This will give you an accounting of how many pages printed on each
type of paper. It's a tad cryptic though. You might consider a
service manual to decipher it, but IIRC it does say page count all
followed by a number of to letter acronyms=#### where each means
something, like HR for high resolution paper, GP for glossy paper,
that sort of thing.

If the printers are not used frequently, I would have fewer
printers.

This is their network model. It's not my favorite as it has the same
resolution as the i860, but you can buy it for about $130.

To be honest, I'm avoiding this model because they shunk the size of
their cartridges. IIRC the big black is down to 19ml rather than
25-26ml. There is a cost per page increase of at least .5c/page
jumping up to the next cartridge, and another .5c/page to this model.
But it's a $100 printer that has network on board, and wifi.
I don't know the button presses to get the printer to print out it's
history.
There are obviously other choices, for the office environment it's not
unreasonable to go with a HP businessjet. These guys take bigger
cartridges and support network.
