It sounds to me like you have some severe fuser thermistor and thermal fuse problems ...i would look into getting an entire fuser assembly sharp part number DUNTW7305DS** last digits depend on your location and power supply

The paper is crumpled in the lower part of the paper.

Maybe you have problems with the upper fuser roller, open the back door and try to see the upper fuser roller and lower pressure roller if you see any wrinkles or damage in any of the rollers that's is the problem, you can replace them just the upper fuser roller and the lower pressure roller but it will need advanced skills, the other option is change all fuser assembly but at higher price

AR-M355 Latent copies.

This make is not my specialty, but if the fuser's been replaced, then it can only be a drum cleaning issue causing that problem.

the machine is detecting a low temerature in the fuser unit. a commen cause is the thermistor digs into the fuser roller and tears the outer skin and the roller. you can check by opening the front door slide out the main unit open the door on the left hand side and you should see two orange rollers. check if the upper roller has a line around it.

Sharp copier m550n

L4-03 is a lock of the fusing motor. It's likely you need to have the fuser rebuilt. You can try resetting the error by turning off the main power switch (located behind the front door under a little plastic cover) and back on. It's likely the error will come back. There's a cleaning screen on the lower fuser roller which gets gummed up with toner and sticks to the lower fuser roller causing it to seize and the motor not to be able to turn causing the L4-03.
