64 ALS 4.0 P R O D U C T M A N U A L EN C O N D I T I O N C A U S E C H E C K C O R R E C T I O N 6.6 Prints Same Information Print controller program closed Use the mouse to display the task bar. On the task bar check to see if the print controller program is open. Use the desktop shortcut to open the print controller program. Print controller not connected Open the print controller program to verity that the software recognizes the print controller. It should display V80i or V84i depending on the model of the controller. Verity that the print controller has power, checking that the power LED is illuminated. Visually inspect the communication cable between the controller and the computer, looking for breaks or damage. Cycle power to the system, as well as closing and re-opening the print controller program. If there is no power to the controller call Alpine Equipment Customer Service. If the cable is damaged it needs to be replaced. Call Alpine Equipment Customer service for further assistance. 6.7 Cannot Read the Print Information Clogged print head Visually inspect the print head. Try purging ink onto a scrap piece of lumber. Flush the system using Matthews cleaner through print head until the fluid comes out clear, this will insure the lines and print head are clear. Dried ink on print head Visually inspect the print head. Try purging ink onto a scrap piece of lumber. Use Matthews cleaner and a brush directly on the print head until it is clean of all ink residue. Low or no air pressure to printer pump (gauge should read 11-14 psi.) The pump is located in the printer cabinet, as well as a pressure gauge and regulator and check the pressure. Adjust the regulator. Air in ink line Verify that ink reservoir is filled. Bleed air out of lines and try printing again. Encoder wheel adjustment Check the encoder wheel. Make sure it spins as the board travels into the saw cabinet. Check that the coupling on the wheel is intact and not damaged or broken. Adjust the spring on the encoder wheel to raise or lower the encoder wheel to a height that allows it to spin as the board enters the saw. Replace the encoder wheel if the coupling is damaged or broken. 6.8 Inconsistent Print Placement Print sensor Check for ink residue on the face of the sensor. Check the height of the print sensor. Use Matthews cleaner on the face to the print sensor to remove ink residue. Lower or raise the print sensor by adjusting the nuts on the top and bottom of its threaded section. Bad lumber load Verify that lumber is against the back fence as it feeds past the printer and into the saw. Verify that the timing and sequence of the infeed process is operating properly. Check for and clear any mechanical blockage preventing the lumber from touching the back fence. Call Alpine Equipment Customer Service is timing and sequence is off. Encoder wheel adjustment Check the encoder wheel. Make sure it spins as the board travels into the saw cabinet. Adjust the spring on the encoder wheel to raise or lower the encoder wheel to a height that allows it to spin as the board enters the saw.
