IJ3000 Controller
The controller gathers and stores all the informa-
tion required for printing a message. This informa-
tion can come from the following sources:
1. The user interface, which tells the controller
what message to print on the product.
2. The photosensor, which tells the controller
when to print.
3. The encoder, which tells the controller how fast
to print. There are two types of encoders:
•A built-in
fixed speed encoder is used when
the conveyor speed does not change.
•An optional, conveyor-mounted variable
speed encoder is used when the line speed
varies or has frequent starts and stops.
With this information, the controller knows exactly
when the leading edge of the product will reach the
print head and at what rate of speed.
The controller comes in a stain-
less steel or painted metal case
that makes it splash-proof and
resistant to electromagnetic inter-
ference. A hinged cover provides
access to replaceable parts.
The IJ3000 Impulse Jet Control-
ler can control up to two 32-chan-
nel print heads or one 256-
channel print head per interface
board. With the optional second
interface board, the system can
control up to four 32-channel
heads or two 256-channel heads.
NOTE: If the controller is config-
ured for dual technologies (Inte-
grated Valve and Impulse Jet) the
Impulse Jet Interface Board must
be the first board plugged into the
CPU Board. The Impulse Jet
Interface Board requires use of
the 24 VDC Power Supply. The
Integrated Valve Jet Interface
Board requires use of the 15 VDC
Power Supply.
