4 Insert each print cartridge into the correct socket (HP No. 57 in the left
socket; HP No. 56 or 58 in the right socket). Make sure you insert the print
cartridges at a slightly tilted back angle.
5 Close the print cartridge latches. If the cartridges are inserted correctly,
closing the latches pushes the cartridges gently into their sockets. Press
the latches to make sure they are seated flat on the cartridges.
Change or install print cartridges only when the carriage is in the “print cartridge
change” position.
If the print cartridge does not fit into its socket, make sure you are inserting the
correct print cartridge into the correct socket. Each socket is labeled with the
correct product number.
