The printer will believe it has zero waste ink when it might have 120ml of liquid sitting on a sponge. 2. Print Head ID Input & Adjustment When you replace the print head on an M2120, you must enter the new head's unique ID (printed on a barcode on the head itself). The adjustment program writes this ID to the main board. Without this, the printer will fire nozzles with incorrect voltage parameters, leading to banding or no output. 3. Bi-Directional Adjustment (Bi-D) This is the only legitimate calibration in the suite. Over time, mechanical slop in the carriage belt or encoder strip causes vertical lines to misalign. The program prints a specific pattern, you scan it, and the printer recalculates timing offsets. This is distinct from a simple "print head alignment" in the driver. 4.
