Fitting the Plug Valve*

The filling hole of this group is shown in the picture left. Please do not pierce the membrane sealing the left hand hole. If you do, then the cartridge is ruined.
Note that we have peeled back the label to give you a clearer view of what the filling hole looks like.
Do not peel the label back on cartridges you intend to refill.
The side casing of this cartridge cannot be removed without destroying the cartridge…..so don’t try it.

We have discovered changes made to the body of this cartridge since it was originally introduced as the first of the Mkll Epson cartridges. This change was made to the filling hole in the base of the cartridge. In the first versions the filling hole had a single diameter. On the latest version the filling hole has two concentric diameters. This means we have to drill out the hole to the correct size to take the Plug valve*.


	To determine if the cartridge needs to be drilled, push the probe from the accessory kit into the filling hole. If it goes all the way home then drilling is not required.

If the cartridge needs to be drilled, use the drill from the accessory kit. This has a stop fitted to the correct depth. If you drill too deeply the cartridge will be ruined.
Fit the Plug valve* in the filling hole and ensure it is pressed all the way home.
Professor Promax recommends the use of a bench drill press to drill the cartridge. This ensures that the hole is drilled true and not distorted.


	Place the Plug Valve* in the filling hole and firmly press it in. Please ensure it is pushed all the way home to properly seat and seal the Plug Valve* in the cartridge.

Filling the Cartridge

Install the cartridge in stand “A” from the optional accessories available.

Place the cartridge in a vice (preferably with protection around the cartridge) so that the base of the cartridge is level…..very important.

If you are using a luer-lok syringe then fit the syringe adaptor to the end of the syringe.

It is good re-filling practice to remove all residual waste ink before refilling a cartridge. The refilling process utilised with the Promax Plug Valve* takes care of this job as you refill the cartridge. However, if you want to recover the excess ink used in the refilling process, this is what you do. Follow the instructions below, using an empty syringe filled with air, BUT hold the cartridge the other way up. Steadily inject the air into the cartridge. This expels the residual waste ink.

Change the waste bottle for a clean one and follow the refilling steps below. The bottle now contains your fresh excess ink which can be re-used.

If you are refilling a number of cartridges at a time, it is a good idea to purge the waste ink from them all first. Remember to wipe the nipple of the waste line before plugging it into a different colour cartridge to prevent contamination of the colours.

Fill a syringe with the correct type of ink, allowing about 15ml more than the OEM fill amount shown in the data table. You can recover this excess from the waste bottle after filling. Expel any excess air from the syringe, up to 2ml of air in the syringe is ok. 5ml of air is about the amount of air the OEM filled cartridge contains.

Fit the syringe into the Plug valve* ensuring a firm snug fit and place the waste tube into the delivery outlet of the cartridge ensuring it is fully home.

Slowly inject ALL but 5ml of ink into the cartridge. When the last 5ml of ink (and any air) is in the syringe, fill swiftly. This will help prime the cartridge.

When the ink enters the cartridge the old ink is expelled through the waste pipe, followed by the air. After all the air is expelled, a mixture of ink and air will be expelled, followed by pure ink. This ensures the cartridge is correctly primed.

Remove the waste pipe and syringe from the cartridge and wipe away ink drops. Ensure the black seal in the delivery nozzle of the cartridge is seated fully home by pressing on it.

Reset the chip using a seven point chip resetter.

The cartridge is now ready for use.

RE-LABEL THE CARTRIDGE TO MAKE IT CLEAR IT IS A REMANUFACTURED CARTRIDGE, PREFERABLY COVERING THE OEM LABEL.
