If the message persists, contact HP support.

there is a rest of the paper jamed still inside the printer you need to remove all the jamed paper then it will work, to find out where the paper stuck's open the front and rear cover, maby you have to remove the toner cardriges as well.

check scan driver, download the latest version if necesary, or may be the scan sensor be damaged

I had something similar but that's because i opened it and modified it with a chip and i forgot to plug back in the power strip for the motor. I remembered after the message, opened it up again and plugs back in the plug and it start working. What i think is that maybe it had a loose connection so if it's under warranty take it back if not go ahead and open it and check the connections for a loos one.

remove all paper from the trays then turn machine off wait a few second then turn back on should reset then reload paper

L6:The Main PWB sensed a Polygon motor lock signal error.

That is related to the mirror motor within the laser.
The laser most likely needs to be replaced.

I'm stepping out on a limb, but I bet it will be the Main Motor. samsungparts.com

Hi there the smudges are most likely down to the black PCU (Drum Unit) and following are the reasons for the two fault caode you have given me.

SC 261 LD HP sensor
not switched
off (for K only)
After the laser beam pitch was
changed, it takes more than
five seconds for the HP sensor
to switch off.
• Defective motor
• Defective sensor
• Mechanical problem
when switching the
actuator
• Brown fuse (FU81) on
the Power supply unit
1. Turn the main switch off and on.
2. Check the sensor actuator position of
the LD positioning motor.
3. Replace the LD positioning motor.
4. Replace the LD home position
sensor.
5. Check and/or replace the PSU.
