4 Printer systems
Printer systems
components (Drive Roller, Spindle Motors, OMAS, etc.) and all non-substrate path components (Carriage,
Scan Axis Motor, Dryer and Curing Heaters, Print Head Cleaning Assembly, Service Station, etc).
Printmech
The ‘printmech’ PCA is mainly used to control motors and fans but it also controls the following:
The Interconnect PCA
The Interconnect PCA controls several motors and is also used as a connections board for some of the
functionality that resides in Printmech board.
• Take-up reel
• Vacuum fans (passes through, the actual control is inside Printmech)
• Front panel
• TOMAS (temperature sensor for the OMAS sensor)
• Valves
• Paper Jam Sensor
Heater Control Board (Petisa)
The Heaters Control Board (Petisa) is a high voltage board with TRIACS, relays, current sensors and safety
components for the external heaters. It has its own Enclosure for safety protection.
Chinda
Chinda board controls the TRIACS and interfacing with a digital interface. It is installed vertically into the
Petisa board.
In order to avoid incorrect installation this PCA has a tab, which must be correctly aligned with the Petisa
board before being fully installed.
Residual Circuit Current Breaker (RCCB)
To protect the printer and the users, there are two Residual Circuit Current Breakers (RCCB) which are
connected between the two power inputs and the Heater Control board. They detect a current leak greater
than 30mA. The customer can reset the RCCB if a circuit blows, but a frequent reoccurrence would
indicate an electrical failure in one or more of the heaters.
Printer/Curing Assembly Power supply
The power supply converts the AC input of the following skus:
• 42inch Printer: 200-240VAC
• 60inch Printer: 220-240VAC
• Scan motor
• Paper motor
• Rewinder motor
• Ink valves
• Ink pressurizing
pumps
• Top fans
• Dryer fans
• Curing fans
• Web-wipe
• IR sensor
• IR Fan
