Instructions for the use of the vacuum refill adaptor HPLuer
The HPLuer is a refill adaptor that works with the vacuum method. It was designed especially for the HP-cartridges HP 932, 933, 950, 951 and tested with more than 1,000 HP cartridges. Trust it- it works.
The HPLuer works with the following cartridges:
The following filling quantities refer to the original cartridges. However, you can only fill in that amount if the cartridge is completely empty.
| cartridge.................. | filling quantity | |
|---|---|---|
| HP 932 black | ||
| HP 932XL black | ||
| HP 933 coloured | ||
| HP 933XL coloured | ||
| HP 950 black | 38ml | |
| HP 950XL black | 52ml | |
| HP 951 | 6ml for each colour | |
| HP 951XL coloured | 8ml for each colour |
Despite its simple construction you should consider a few things when using the HPLuer. Please read these instructions thoroughly and start refilling afterwards.
How to refill HP cartridges:
Before refilling you need to seal all air vent holes. Place adhesive tape on the air slot next to the original-label. On some cartridges you need to stick it around the edge (picture 1). Please consider that the cartridges HP 950 XL and HP 932 XL have two aditional vent holes. These need to be sealed as well otherwise creating the vacuum inside the cartridge is not possible (picture 2).
Draw the recommended amount of ink into the Luer-Lock syringe. Afterwards screw the HPLuer onto the top. Now put the HPLuer on the ink outlet of the cartridge (picture 3). Press it firmly onto the cartridge to seal the opening airtight (picture 4).
Pull the plunger of the syringe up to the maximum mark (picture 5). That creates a vacuum inside the cartridge which you can see on the basis of air bubbles rising through the ink. Hold the plunger in this position until no more bullbes arise. Release the plunger. Due to the vacuum the ink is sucked into the cartridge. The plunger slowly moves down. When it is no longer moving, carefully press the remaining ink into the cartridge. As a last point pull the plunger a little bit up. By that the pressure is compensated. Your cartridge is now refilled.
