The relay door is the door on the lower right side, below the duplex unit. Check this door -- it may not be closed all the way, or the actuator (the piece of plastic that sticks off the door and is the part that blocks the sensor) may be broken. If neither of these is the case, the sensor may be bad.

ERROR MESSAGE: COVER IS OPEN AS SHOWN. CLOSE COVER. IT IS SHOWING IN THE PICTURE A VIEW ON THE RIGHT SIDE BOTTOM TRAY.


Hello!
Make sure that all off the covers and doors are properly closed.
If you are sure that everything is closed you probably have a faulty switch or a broken gate in the bottom tray.
See you!

If in the control panel don't show any places or any door, change the switches on the front cover area and the switches of the fuser area. If the problem continuos check the laser area.

Codigo sc-322-000 copier ricoh aficio 450


sc322 is an error generally caused by a component in the laser unit. However, sometimes a faulty door switch can cause this error as well. The switches in question are the three micro-switches that change state when the right door is opened or closed. They are located on the front right side of the copier, above the fusing unit and behind a plastic cover. If you can remove these switches and test them individually, you can probably find the faulty switch. If not, you can replace all three as a set and hopefully the sc322 error will go away (once you reset the machine).

If replacing the switches do not fix the error, then the problem lies somewhere in the laser unit, possibly with the polygon mirror motor, but your best bet is to replace the whole laser assembly if you can.

Hope that helps!

Flase door open reading on my aficio 350. The door is shut. The machine is showing that the door is open but it not. It close as it should be.


when the door closed it actually activates the switch. see on the door if any plastic piece from the frame is broken or not and locate where in the machine does the front cover activates switch. it will be easy to find the broken part.

Sharp 336


My suggestion is to check the relay in the back of the machine,
I used to get that code with a toshiba, In the back to the right there is a relay with a switch, sometimes it would pop the switch.
Another thing that caused that was a small transformer.

Not sure if sharp is the same.
good Luck
