Carriage Error: Encoder Strip Malfunction
This error indicates a problem with the encoder strip, a clear plastic strip that tells the carriage its position. If dirty or damaged, the printer cannot track carriage movement accurately.
- 1Encoder strip is dirty with ink, dust, or debris, obstructing the optical sensor's ability to read the lines.
- 2Encoder strip is physically damaged (creased, scratched, torn, or detached from its mounting points), leading to inaccurate position feedback.
- 3The carriage assembly's encoder sensor (optical sensor) itself is faulty or misaligned, failing to correctly read the encoder strip.
- 4Contamination or damage to the carriage motor's encoder disk or sensor, which can indirectly affect carriage positioning feedback.
- 5Excessive friction or obstruction in the carriage path preventing smooth movement, causing the carriage to stall and trigger a position error.
- Printer displays error code '23:10' on the front panel.
- Carriage movement is erratic, jerky, or completely stalled.
- Print quality issues such as vertical banding, misaligned lines, or distorted images.
- Printer makes unusual grinding or squealing noises during carriage movement.
- The carriage assembly repeatedly attempts to move but fails to reach its home or service station position.

A transparent plastic strip with precisely printed markings that the printer uses to determine the exact position of the carriage as it moves across the platen.
A numeric or alphanumeric code displayed on the printer's front panel or in diagnostic logs that identifies a specific hardware or software malfunction.
The mechanism that moves the printheads back and forth across the media during printing. It rides on a guide rail and is driven by the scan-axis motor via a belt.
Software that converts vector graphics, text, and images into a raster (bitmap) format that the printer can output. Essential for processing complex design files.
