Print Module Replacement / Height Adjustment
CAUTION: Turn off the power to the printer before removing or inserting the print module(s).
DUE TO THE TOLERANCES IN THE PRINT MODULES AND OF THE PRINT HEADS THEMSELVES, THE ENTIRE PRINT MODULE MUST BE REPLACED - ONCE A PRINT HEAD HAS REACHED ITS END OF LIFE.
1)Remove the ink cartridge from the printer in order to remove the print module.
2)Remove the print module by holding the release lever to the right and lifting the print module from the printer using its handle.
3)Insert a replacement print module in the reverse order.
4)If the replacement print module does not function properly by swinging the print heads out to the print position, the module stop block may need to be adjusted. These stop blocks are located beneath the print module under the front nose cover of the machine. With the power off remove the cover by removing four screws, two on either end of the cover then while holding the active unwind pinch roller down slide the cover forward far enough to unplug the front panel PCB. Once the PCB is unplugged - remove the cover and set aside. Adjust the print module stop block as needed to cause the pinion gears (B) to fully mesh without binding. This is achieved by loosening the two screws (A) securing the stop block to the frame and then moving the stop block right or left to cause it to raise or lower. Retighten the screws once the proper height is reached.
5)Replace the cover and perform the auto cleaning until the print heads are filled with ink and printing a full image.
6)As a final test of the print module installation, run a test pattern to check the print quality. You should observe an even grid of rectangles.
