If the 1226 error appears during the startup, it could be caused from a pending print job.
Remove the USB cable from the printer.
Restart the printer.
Clear all pending print jobs from the computer.
If the error still persists, it could be cause by an over-tight movement belt of the table or table movement problem. Contact Melco Tech.

“0003 No enc pulses” on the table display and on the top display it is blank

 

Most likely, the encoder disk at the back side of the printer (and under the small metal cover) is dirty and cannot be read properly by the sensor.


Just use a cloth with isopropyl alcohol and clean this disk from both sides (by slowly moving the table in-out).


Do a self test by pressing and holding the eject button before powering up the printer. It should say 'self test ok'
