My J1 worked has been working well for 2 months with nice surfaces, and abruptly my printings start to exhibit an in printing offset. It appears on Xand Y axis (more marked on X axis), starts at 11mm high, extends to 10 mm then disappears. Exactly the same defect on several prints. What kind of mechanical trouble could be involved in this short-lived offsetting ?
Any suggestion regarding this trouble would be more than highly appreciated…
