INTRODUCTION
The Macrojet 2 large character printer consists of:
• The print head (up to four can be fitted to one cabinet)
• The control cabinet
• The product detector (one or two can be fitted)
• The disposable ink supply container.
Print messages are normally entered using a Domino Pocket Terminal.
Print heads can be supplied to print with either 7 or 16 ink drops and in a
range of character heights (see
page 2-7). Each is a separate stainless steel
assembly connected to the cabinet by a flexible conduit and will work in
any position. Print heads can be added or changed without difficulty.
The control cabinet contains an ink system supplying ink to the print
head(s) and an electronics control system. Controls and external
connections are grouped on a panel at the rear.
The product detector is mounted on the line and senses the product as it
approaches the print head. There are three optional types: two are infra-red
beams and a third works by metal detection.
Ink is supplied in a disposable 5 litre bag-in-box ink container, connected to
the printer by a Quick Connect/Disconnect (QCD) connector.
Messages to be printed are normally entered as serial digital data from a
Domino Pocket Terminal, but it is also possible to control the printer from a
separate computer system (details from Domino).
The printer contains a set of separate auxiliary alarm contacts which can be
connected to external indicators or other equipment. An optional alarm
beacon is also available to show the printer status.
Another option is a shaft encoder which allows the printer to follow line
speed variations. This includes the slowing down and speeding up
involved in line stop and start.
