When the ink reaches the rectangular patterned area (on base of bladder spring device) of the metal
frame, flick down the red lever. This will effectively balance the cartridge by shutting off withdrawals
from the lid valve, and by sucking out air that will cause airlocks (via the head)

Although normal fill weight for 29 type cartridges is around 63 grams, we only test at approxi

mately 60g or less - and normally ship out at 58~59.5 grams
·
If you overfill the cartridge, you can draw excess ink out of the cartridge by simply evacuating
ink in the evacuating station. Remember short split second bursts will normally draw off around 1ml per
time, so be careful not to drain too much out.
·
Then go to test print. It is imperative to spend this time test printing.
·
Test print must be 2 pages (minimum) using normal quality print mode. (You can use the test
shown below)

Do not use water in the process (on the head)

Make sure that your blue tape also covers the mazehole
2) ADDRESSING 45 & 15D CARTRIDGES
The process is far simpler and we will use one section for all concerned points: -
·
The cartridges are identical, with the exception of slight electronic differences
·
Therefore the vessel and all other aspects for a recycler are identical
·
First we get our cartridge and nozzle test with a high-grade tester so as to deduce what the firing /
working count is from the possible 300 jets on these models. You may use our MS-ECD which besides con
-
verting 45 to 15 cartridges, it also tests 15, 45, 23, 25 & 41 cartridges: http://www.oliser-tr.com/equipment/
ecd.htm. By-in-large though, a tester is not needed and at over US$2,000 for the converter it is not some
-
thing everyone can afford.
·
You can also use a printer with a happy (smiling) and unhappy face. Make sure that the cartridge
contacts are clean (clean with mentholated spirits) and ensure cartridge goes to happy position on black car
-
tridge face, after you re-open the printer lid
·
If it does, this tends to imply that 270+ of the 300 jets are working. On the 45/15 cartridges, they
tend to work satisfactorily with UP TO 10% misfiring jets
·
NB: The best way around a tester, and in fact a dual-method that is best employed as an additional
test is to get an older model HP printer, such as HP710, 720, 820 etc. and use the utility software in the HP
TOOLBOX to fire the jets on cartridge services facility. If the cartridge has NO ink in it, you can part fill or
hand-suck to prime ink to the head for the short test. This will display the grid pattern letting you know the
nozzle condition.
·
Steam nozzles. NOT for too long, or you will melt the holes closed!!! 2 ~ 5 seconds at varying dis
-
tances is recommended (but immensely important). If you DO NOT steam first - you will be trying to force
ink into the cartridge during the fill through clogged passages a) causing irreparable damage to those jets,
and b) slowing down fill times
·
Evacuate ink in the cartridge until cartridge weighs 64 ~ 66grams. It is important that aftermarket
ink does not mix with OEM ink, bearing in mind that HP has patents on their ink formulae and the different
chemical properties may clash.
·
Some clients do flush cartridges internally with pure water and thereafter evacuate it. We believe that
this is not normally required if virgins or even 3-filled cartridges are being processed.
·
Ensure that the filling ink line (tube) from cradle to ink bottle is primed, i.e. no air in it. You may
achieve this by always saving old and faulty cartridges and start the fill allowing ink to go into the old car
-
tridge first. This is only necessary when changing ink bottles.
·
Immediately after the cartridge has been in evacuation station, insert to fill station. Why? - you might
ask….because in the evacuation station, the silver bag has been squeezed together flat and no air is present,
therefore when you fill, we will reduce the chance of air in the bag
·
Obviously next: fill
·
BUT DO NOT BALANCE – if you can help it (this mainly pertains to recyclers who are producing stock,
or those who have good turnaround times to clients in that they were not rushed)
