Hewlett Packard (HP) Printers have always been one of the most popular makes owned by our customers in Coventry. We have been very successfully refilling HP ink cartridges for years. Years ago, a typical HP black cartridge may have had over 20ml of ink volume. More recently, something between 6 and 10 ml is much more common, with many being even smaller than that. Consequently, the price may have dropped a little but the cartridges seem not to last anywhere near as long as they used to do.
The Ink Cartridge Refilling Process
Many HP ink cartridges can be refilled to a significantly higher volume than they were originally designed to be. We electrically test all HP cartridges before refilling them, we empty them, clean the print head and electrical contacts, flush out the old ink, clean them again and then refill them with ink that has been specifically formulated for each cartridge type. After refilling under vacuum with state of the art equipment, often with extra ink volume, we electrically test them again, clean, reseal and re-label them.
Look out for our Plus (+) and Double-Plus (++) Versions
Many cartridges are refilled at Coventry Photo Centre to three different volumes: standard, plus (+) and double plus (++). The standard version is refilled with the same volume of ink as quoted by HP …. or more! The plus and the double plus versions will have volumes that are significantly more. One of the most popular refills is the HP 21 black cartridge, see below ….
Some Hp 21 ink cartridges have a very small sponge inside. These can generally only be refilled to the standard volume. However, some also have larger sponges inside, we identify these and we then create much larger volume versions. We do a plus version with roughly double the original volume and a double plus version with at least three times the original volume. We can always tell our customers what volume a certain cartridge has been refilled to. All individually refilled HP ink cartridges are fully electrically and print tested at Coventry Photo Centre before we sell them, meaning that we are very confident about their quality and reliability.
Guarantee
All refilled ink cartridges come with a no-quibble full money-back guarantee at Coventry Photo Centre.
We’ve been doing this for a long time and our return failure rate is incredibly small. However, we are mindful of the fact that we are refilling a product that has already been used before and, as with new original cartridges, they can occasionally fail. If it does go wrong, we guarantee to put it right!
If you’ve got an HP printer and the cartridges are running out very quickly or you feel that you are paying too much for them please give us a call. We can almost certainly save you money and we can probably supply cartridges with more ink that’ll last you longer.
