• Code: 261
• Description: LD HP sensor not switched off (for K only)
  After the laser beam pitch is changed, it takes more than five seconds for the HP sensor to switch off.
• Causes: • Defective motor • Defective sensor • Mechanical problem when switching the actuator • Brown fuse (FU81) on the Power supply unit

• Code: 285
• Description: Line position adjustment (MUSIC) error
  Line position adjustment fails four consecutive times.
• Causes: • Pattern sampling error due to insufficient image density of patterns used for the adjustment • Inconsistency in the sampling line position adjustment pattern due to dust on the pattern, damage to the OPC drum, damage or toner dropped on the transfer belt, or a dirty or defective ID sensor
