It is best practice to power off the printer before swapping the cartridge if switching between partially used ink cartridges on the
same printer, such as when you switch from one of three types of ink available for these printer models (Dye, Dye plus Ultra Black, and Pigment).
If the cartridge is removed while the printer
is trying to read it, there is a small chance it will be damaged and become unreadable (Cartridge Data Error). Powering
off the printer first will ensure this can not happen. Under normal use, you
would only remove the cartridge when it is empty. In this case, it is not necessary to
power off the printer because the cartridge being removed will be discarded, and
it will not matter if it is damaged.
Note: In general multiple installations of the same cartridge over and over again can cause problems with the contact points on the cartridge. The small electrical contact pads on the cartridge develop a
small dimple from the force of the contact point in the carrier
assembly. These dimples can get deeper or move slightly with every
re-insertion of the cartridge. Eventually, the depth and breadth of the dimples
may result in a loss of electrical connection across the contact, and subsequent
cartridge read errors. In our testing, we saw consistent problems after about ten re-insertions of the
cartridge but it is possible problems could occur with even fewer re-insertions. The cartridges are not designed for continual swapping.
