Croma24 Service Manual
The latest firmware version was included and installed onto the
computer during the installation process. To upgrade the firm-
ware on the printer, open the Control Panel with the printer
online. During the initial start up of the Control Panel, it commu-
nicates with the printer’s firmware. The Control Panel is collect-
ing information stored on the printer such as current ink levels
and the firmware version. If the Control Panel finds an older
version of firmware, it automatically installs the latest version
that is stored on the computer.
This communication between the Control Panel and the printer
happens every time that the Control panel is opened.
NOTE
The printer’s firmware will revert back to version 1
(the original version) if power is removed from the
printer for any reason.
To assure that the latest version is loaded onto the printer, it is a
good practice to run a “Prime” every morning that the printer is to
be used. This forces the user to open the Control Panel, which
verifies that the latest version of firmware is loaded.
It also helps the cartridges to purge any possible obtructions
within the jets before clogging begins by firing all the jets for a
period of time.
Internal Cabling and Signal Flow Diagram
Figure 3-36 is a schematic of the major components and the
cabling associated between them. The diagram depicts component
boards or assemblies, jack connections, cables, and signal flow. It
is to be used by the technician as an additional aid in trouble-
shooting and improve understanding of the printer theory of
operation.
