The company has been explaining that Armor cartridges designed to be compatible with certain HP printers may be affected by recent HP modifications.
As Armor explains, if you have bought Armor cartridges for a printer designed to use HP302 or HP304 cartridges, you may have been experiencing compatibility issues.
These issues are due to modifications made by HP on printers produced from May 2018, which went on the market around September this year.
Armor has given instructions on how to determine whether or not your compatible cartridges will be able to be effective in your printer by working out the production date of your device and says, in the case of any issue, to contact your distributor.
