If you need to adjust this for some reason, you must remove the Maintenance Unit from the Main Unit because you cannot touch the WL Positioning Cam fixing screw without removing it. In case of the unit replacement, this part is pre-adjusted at the factory.(19) Connect the Drain Tube to the Fitting, and then connect the connectors to the PCB in the rear.Īdjusting or checking the height of the Wiper Blade to the Wiper Guide Shaft (18) Fasten the four bolts (in the red circles shown below) in the front and rear of the Maintenance Unit securely. The Gauge's concave parts show the allowable range (+/-1 mm) of lateral position of the Print Head Cap Rubber Rips. Put the MNT Check Gauge on both the left and right W Guide Shafts, and then set the Gauge at an angle so that the left reference side of the Gauge attaches the Stopper of the Carriage Guide Shaft. Use the MNT Check Gauge to check the lateral direction of the Maintenance Unit for the arrival check etc. When installing or removing the Maintenance Unit from the Main Unit, simply fitting the pins in the slits determines the lateral direction of the Maintenance Unit. Normally this adjustment is not needed because the position of the Adjusting Board for the Main Base Tray is pre-adjusted with the jig at the factory. (17) Attach the MNT Check Gauge's reference side to the upper and lower Carriage Guide Shafts, and then confirm that the Rip of the Print Head Cap Rubber is within the Gauge's concave part that shows the allowable range for the lengthwise position (allowable range: +/-0.65 mm).Īdjusting the Maintenance Unit position in the lateral direction (the Print Carriage's scanning direction).
