Question about Sharp AL 1631 Copier
I read on your site that a 3H error code on my Sharp AL-1631 copier means that it has an overheating problem. How can I go about checking and/or replacing an exhaust fan? Is that under the case on the left side of the unit, above the power switch? And where can I purchase the part?
Hi, H3 is abnormal high tempeature in the fuser. Never had issues with the fan, probably you have a 'melt down', inspect the fuser through the sprung loaded flap and see if the three picker fingers that rest on the roller are melted. If they are then you require a fuser rebuild to include both fuser rollers, fingers, bearings and thermal fuse.

Hi, i fix the 3h code with Andy's reset solution the only extra was to open the side feeder and close it again.

Mark, yes L4 is main motor, do the reset again. If L4 reappears i still think you have fuser issues. Being very careful not to electricute your self, remove the fuser by the two chrome screws, leave still connected, as you look at the machine from the end, lower left hand side should be a chrome plate, which when pressed in makes the door switch. Switch the machine on while holding the fuser, make the door switch. Machine should turn over, also you should see the heater lamp come on.

Hi, try a main board reset by pressing these buttons= cancel, exposure, cancel, exposure. Display has to go dead, enter 14 then print. Should reset however if there is an on going fault then H3 will return. If it does then your thermal fuse, located in the fuser unit, will need replacing.
