Quick Diagnosis

If the printer locks up and shows '5B00' on the screen when trying to print, the purge counter has hit the limit. This error is a preventative measure to avoid overflowing residual ink onto sensitive electrical components.

Step-by-Step Solution

  1. Enter service mode: With the unit off, press Stop and, without releasing, press Power.
  2. Reset: Without releasing Power, release Stop and press Stop 5 times.
  3. Execution: Release both buttons; the light will flash while the counter resets.
  4. Verification: Turn off and on again to exit service mode.

Prevention and Maintenance

Avoid running repeated deep head cleanings via software. Excessive cleanings fill the absorber much faster than normal printing.
