6.6.3. Print Cartridge Maintenance
The top of the carriage contains a spring latch for the print cartridge. The spring latch provides tension for
consistent snap-in of the print cartridge. The print cartridge should only be replaced when the carriage is in
the designated service position, which is controlled from the product's front panel.
When installing a print cartridge, the bottom portion of the print cartridge should be installed into the car-
riage assembly as shown in Figure 6.10.2 Once the bottom is seated in the carriage, push the top portion of
the cartridge toward the carriage until it snaps into place beneath the spring latch. Always ensure that the
electrical contacts inside the carriage are clean. Do not handle or touch the contacts because oil from the
user's fingers can corrode the electrical contacts (see Figure 6.11.3 in section 6.11.1.2.1 for carriage and
cartridge contact cleaning instructions).
The service station, at the left end of the carriage path, contains two wipers and two nozzle caps to provide
servicing and capping for either a monochrome or a color print cartridge (see Figure 6.10.3). The caps and
wipers are mounted on a rotary assembly, which incorporates a micro-switch for accurate positioning.
