  • Page 23 Part 1: Safety and Precautions BJ-W9000 1.2 Ink 1.2.1 Ink passages Be careful not to touch the ink passages of the printer or to allow ink to stain the workbench, hands, clothes or the printer under repair. The ink flows through the ink bottle unit, sub-tank unit, carriage unit, purge unit, nozzle check unit, waste ink tank unit and the ink tubes that relay ink to each unit.
  • Page 24 BJ-W9000 Part 1: Safety and Precautions 1.2.2 Ink mist Since the BJ print head prints by squirting ink onto the media, a minute amount of ink mist is generated in the printing unit during printing. The ink mist is collected in the printer by the airflow.
  • Page 25 Part 1: Safety and Precautions BJ-W9000 1.3 Electrical Parts Although connected to the AC power supply, the printer is only activated when its power switch is turned on. At the rear of the main unit are the system controller, image process controller, head controller, mechanical controller, motor controller, power supply unit, interface connector, and optional connector.
  • Page 26 BJ-W9000 Part 1: Safety and Precautions 1.4 Size and Weight of the Printer This printer has service parts which are large and heavy. Be careful not to get your fingers caught when carrying the printer or setting down the parts during assembly or disassembly.
  • Page 27 Part 1: Safety and Precautions BJ-W9000 2. OTHER PRECAUTIONS 2.1 BJ print Head 2.1.1 How to handle the BJ print head Do not open the BJ print head package until you are ready to install the head. To install the BJ print head, gently remove the protection cap from the nozzles. Do not replace the protection cap once you have removed it from the BJ print head, since the cap may scratch the nozzles.
  • Page 28 BJ-W9000 Part 1: Safety and Precautions 2.1.2 Capping The printer will perform the capping operation when printing has finished or during standby due to errors, in order to protect the BJ print head and avoid ink leakage. If the AC cable is accidentally unplugged, turn the power switch off, reconnect the AC cable, and turn the power switch on to confirm that the printer starts up properly and changes to the “Ready”...
  • Page 29 Part 1: Safety and Precautions BJ-W9000 2.2 Ink Bottle 2.2.1 Opening the ink bottle Do not open the ink bottle until ready to use. To prevent foreign matter from entering the ink supply unit, install the opened ink bottle immediately.
  • Page 30 BJ-W9000 Part 1: Safety and Precautions 2.3 Handling the Printer 2.3.1 Spur tips Do not bend or damage the spur tips. Although the spur tips contact the printed sheets, the contact surface is small and the quantity of ink is so minor that the printed sheet will not be spoiled. However, if the tip are deformed, more ink will get transferred as the surface contacting the printed sheet becomes larger, and the ink may spoil the sheet, creating dotted lines.
  • Page 31 Part 1: Safety and Precautions BJ-W9000 2.3.2 Precautions against static electricity Certain clothing may generate static electricity, causing an electrical charge to build up on your body. Such a charge can damage electrical devices. In particular, never touch the BJ print head contacts.
  • Page 32 BJ-W9000 Part 1: Safety and Precautions 2.3.3 Fixing the carriage Although the carriage will cap the BJ print head after the completion of printing, it has no mechanical lock. When transporting the printer, use the carriage fixing plate which comes with the printer to fix the carriage at the home position, so as not to allow the carriage to move.
  • Page 33 Part 1: Safety and Precautions BJ-W9000 2.3.4 Installing the printer Place the printer in a horizontal position, and check it using the service level tool. If the printer body is not horizontal, paper-feeding or printing problems may occur. 2.3.5 Replacing the waste ink tank The waste ink tank must be replaced when it becomes full.
  • Page 34 BJ-W9000 Part 1: Safety and Precautions 3. PRECAUTIONS WHEN SERVICING THE PRINTER 3.1 Stored Data This printer counts the number of printed sheets, the number of ink bottle replacements, the number of scans, the number of cleanings, and the cutter usage, and stores this information in the system controller SRAM (IC452).
  • Page 35 Part 1: Safety and Precautions BJ-W9000 3.2 Firmware Confirmation Firmware has been downloaded to each of a System Controller, Carriage Controller and Motor Controller. When replacing each board with the one with Service Parts, confirm that each firmware is the latest version. If it is not the latest version, please update it to the latest version.

This Pause between Scans function is useful when printing using a printing paper that needs time to dry out, for example film-type printing sheets.
  • Page 153 BJ-W9000 Part 4: Technical Reference 3. PRINTER'S MECHANICAL SYSTEM The printer is comprised of two major working components: the ink passage and the paper path. The ink passage consists of sub components including the ink bottles, the sub tanks, carriage (in which the air buffer and the BJ print heads are installed), the purge unit, and the waste ink tank, all of which implement the supply, circulation and suction/removal of the ink.

When the sub tank ink sensor consistently cannot detect ink, although the ink supply to the sub tank is being attempted, the sensor indicates that ink is out.
  • Page 157 BJ-W9000 Part 4: Technical Reference e) Check valve The check valve on the ink tube, connecting the ink bottle and the sub tank, prevents the ink leakage from the tube during ink bottle replacement. f) Ink leakage detector The ink leakage detector is at the bottom of the rear of the unit. It detects leakage in the printer through the conductivity of ink.
  • Page 158 Part 4: Technical Reference BJ-W9000 3.3 Sub Tank Unit 3.3.1 Construction of Sub Tank a) Open sub tank The printer provides six open sub tanks for each of the six color inks.

If you need to move the carriage or to perform "ink drain" when the power is turned off, the pressure on the caps and lever has to be manually released.

Turn the protection cap/ wiper rise and fall camshaft by inserting the slotted screwdriver into the notch on the protection cap/ wiper rise and fall camshaft. (When the protection cap / wiper rise and fall camshaft is turned, the protection cap also rises or falls.)
  • Page 254 Part 5: Maintenance BJ-W9000 5.4 Ink Drain There are two types of "ink drain", one is an automatic ink drain and the other is manual ink drain. The "ink drain" discharges all the ink from inside the ink passages, about 900ml (about 150ml x 6 colors).
  • Page 255 BJ-W9000 Part 5: Maintenance b) Outline of manual ink drain Follow these steps to perform manual ink drain. Step 1 Both the ink that is in the carriage unit, and the ink contained in the ink tubes which connect the carriage unit to the sub-tank unit, should be poured into the sub-tank at the same time.
  • Page 256 Part 5: Maintenance BJ-W9000 c) Steps for manual ink drain (Page 5-38 and 5-39). Step 1 1) Open the right lower cover, and lift the ink bottle locking levers for all 6 colors. 2) Remove the rear lower cover, the right cover, the rear right lower cover, and the rear upper cover.
  • Page 257 BJ-W9000 Part 5: Maintenance Step 3 12) When no more ink is being discharged by following the procedure in step 2, close the C-S valve and then change the ink passage for another color. See (Page 5-32). Again, pull the syringe plunger, and suck up ink, discharging it into the waste tank etc.
