1. Directly Increasing the Single Adjustment Step: Many people, upon discovering a large deviation, directly adjust the step size to over 0.5mm. This easily leads to over-adjustment, causing the deviation direction to repeatedly switch, wasting time. The correct approach is to control each adjustment within 0.05mm, testing after each adjustment to gradually align.
2. Skipping Cleaning and Directly Adjusting Parameters: Most deviations are caused by ink or lint jamming the positioning pins. Many people skip cleaning and directly tighten bolts and change parameters. In reality, the deviation disappears automatically after cleaning, resulting in wasted effort and easily disrupting the original positioning reference.
3. Adjusting Position Without Checking Tightness: After adjusting the position, uneven bolt tightening (one side tight, one side loose) will cause the printhead to tilt, leading to misalignment again after a period of printing. The correct operation is to tighten the bolts evenly diagonally, and after tightening, shake the printhead to confirm it is not loose.
4. Adjusting each printhead individually without a reference: When multiple printheads have deviations, adjusting the position of each printhead individually without first establishing a reference printhead will cause all printheads to become misaligned, leading to increasingly chaotic adjustments. The first printhead must be calibrated and used as the reference before aligning the others one by one.
5. Ignoring transmission wear and only adjusting the printhead: If the deviation is caused by wear on the transmission gears/chains, simply adjusting the printhead position will not solve the problem; the printhead will misalign again after running a few dozen prints. In this case, the transmission clearance needs to be calibrated first, and then the printhead position adjusted to completely resolve the issue.
6. Not saving parameters or conducting continuous testing after adjustment: Many people adjust the position, print one piece as a test, and stop without saving the parameters. The printhead will revert to the deviation state the next time it is turned on. They also don't conduct continuous testing, only discovering the misalignment after producing dozens of prints, delaying production.
