STATION 3 PCB ASSY - E106328

E106328 – Station 3 PCB (Station 3 PCB Assy) – Mimaki UJF

The Station 3 board (E106328) is fitted to Mimaki printers. It controls the functions of maintenance station no. 3 and communicates with the main electronics.

The Mimaki UJF-3042 maintenance manual describes the "3042 Station3 PCB Assy" as a board mounted in the table ("Mounted position: Table part"): it drives the table up/down stepper motor, the Z origin sensors and the suction fan, and exchanges commands with the main board (Main PCB) over a serial link.

Technical specifications

• OEM reference: E106328
• Manufacturer: Mimaki
• Part type: Maintenance station PCB (Station 3)
• Manufacturer designation: "3042 Station3 PCB Assy"
• Location: Table ("Table part"), according to the UJF-3042 maintenance manual
• Connectors: CN5 stepper motor; CN9 20-pin, serial inputs/outputs to the Main PCB; CN11 suction fan; CN12 Z origin sensor; CN13 JTAG (CPLD); CN15 pin 2 Z origin sensor
• Power supply: +35V; measuring points +35V, +5V, +3.3V, +1.5V
• Fuse: F1 3.15 A (AC125V / DC60V)
• Diagnostic LEDs: D1 (fuse F1, off if blown); D9 (Z origin sensor)
• Note: This page describes the board as a maintenance station board (capping/cleaning, nozzles left unprotected). The Mimaki UJF-3042 maintenance manual assigns the "3042 Station3 PCB Assy" to table management (Z height motor, origin sensors, suction fan), not to capping or cleaning. The reference E106328 does not appear in the pages of the manual consulted: the match is based on the designation. Compatibility with the Mimaki UJF-3042HG and UJF-6042 has not been confirmed by an independent source: check against your machine reference before ordering. Do not confuse with the "Station 4 PCB Assy" E108310 of the UJF-3042MkII / UJF-6042MkII.
• Shipping: Ready to install

Compatibility & use

• Mimaki UJF
• Before replacing the board, check LED D1: if it is off, fuse F1 has blown.
• Also check the link to the Main PCB (CN9), the Z origin sensor (CN12) and the table stepper motor (CN5), which are connected to this board according to the UJF-3042 manual.

Function

• Drives the table up/down stepper motor (CN5), according to the Mimaki UJF-3042 maintenance manual
• Reads the table upper and lower origin sensors (Z origin, CN12)
• Controls the table suction fan (CN11)
• Exchanges commands with the Main PCB over a serial link (CN9, 20 pins)
• Controls the functions of the maintenance station (capping/cleaning)
• Acts as the interface between the main board and the station parts
• Takes part in the correct running of the maintenance cycles

Signs of wear

• Table no longer moves up or down, or Z origin not detected (possible fault in the board or in the connected parts)
• Table suction inoperative (fan connected to CN11)
• LED D1 off: board fuse F1 blown
• Faulty maintenance station
• Capping/cleaning inoperative
• Nozzles left unprotected
• Machine stops

Replacing this part restores the machine to proper working order.
