Refilling laser printer cartridge

I bet you wish you had a real, functioning brain!

The printer works real well and I'd like to continue using it.

Some mfrs quote a full and empty weight.
I weigh new cartridges, and label them with initial weight
with date.
If I ever get to refilling the info will be useful.
My service manual gives cartridge weights, shelf life in
sealed bag, and post installation life. This might
indicate that toner has a shelf life once it is exposed
to air. If so is humidity a factor in this?
Any opinions?

I do not know this printer or cartridge. But from a little research it appears
it has a drum built in which means that it will probaby be good for 1 to 2
refills after which the drum will have to be replaced.
Also, since it has a drum the waste toner will probably be in a separate
compartment although it is possible that it is returned to the main toner
hopper.
You may well be OK with 2 refills without there being a problem with waste,
also if you empty out the hopper after you drill the hole then any waste will
be removed if it is kept there.
(In cartridges that have waste returned to the main hopper it is critical to
remove all toner from that area before refilling because the waste will cause
light print.)

The supplier of the toner should provide full instructions - see

for an example of one that does.

Tony,

Thanx for taking time to reply. My printer is a NEC Superscript 860 and
the cartridge # is NEC 20-080.

I can buy the toner for that printer and a hole-burning tool for about
$25. I think I know the appropriate area of the cartridge where to burn
the hole.
(There is no fill hole and I don't have a functional diagram of the
cartridge.)
I realize the burning will produce an odor & fumes and that the toner is
very fine -- thus I will do it in a work area.

Also, I will have to judge how much toner to pour from the bottle/funnel
into the cartridge. (I don't know anything
about a waste compartment .)

I phoned Cartridge World and they cannot fill this cartridge. Thus my
only option is to try to fill it myself after gathering information.

Let me know if you have any specific info about this cartridge that could
help me.

Depending on the model this should work well. The only longer term issue
is
that the waste compartment in the cartridge will eventually fill and
overflow
but not all cartridges have such a container.
Also with some cartridges there are components that will wear out.
I would be surprised if remanufactured or compatible cartridges are
unavailable.
If you can provide the make and model I should be able to give you more
information.

Humidity tends to work against anything, but from personal experience
I have used an HP Laserjet III cart that was sitting in an open, then
re-ziplocked, bag for about 5 years and it worked fine.
