Solutions

Quick Diagnosis

The 1890 error is triggered when the print carriage hits a physical barrier. If you notice a loud sound when powering on the unit followed by this code, it is almost certainly a remaining piece of shipping material.

Step-by-Step Solution

  1. Power off: Unplug the power cable from the wall outlet.
  2. Internal check: Open the front access cover and gently slide the ink carriage to inspect for orange tape or foam.
  3. Remove obstructions: Carefully peel off any leftover adhesive or cardboard protective pieces.
  4. Power cycle: Close the cover, reconnect the power, and turn the printer on to initiate a self-calibration.

Prevention and Maintenance

Always ensure all protective orange tapes are removed upon unboxing a new device. Avoid using off-brand cartridges that may not click into place correctly, as they can cause carriage jams. Regularly dust the interior of the machine with a dry cloth to prevent debris build-up.

When to Call a Technician

If you have thoroughly inspected the carriage path and removed all obstructions, yet the 1890 error remains, the internal carriage sensor may be malfunctioning and require expert repair.
