Sharp AL1631 Copier Intermittent Problem

I have an intermittent problem with my copier. Sometimes when I turn it on the Ready Light above the Copy Button keeps blinking and there is a very faint clicking sound. The copier does not respond to the Copy Button. There is no error code in the display. It just sits there in this mode until I turn it off. Sometimes when I turn it on it works like it is supposed to.


I have recently replaced the toner cartridge but it did this before replacement too.

Re: Sharp AL1631 Copier Intermittent Problem

There are several reasons this could be happening.

1. If you are not using Sharp Genuine products

2. The toner cartridge might not be fully seated

3. Voltage for the specified plug may be incorrect voltage or overloaded.

The faint clicking sound is most likely the machine stirring toner. I have seen where a sensor that detects toner level inside the developer unit get covered in a sludge, but if you just replaced the TD unit it should be okay.

Upon replacing the drum on my Sharp AL-1631, the drum indicator light is still illuminated and the copier still won't function. Is there something I need to do after replacing the drum to get it to copy...

To reset the drum light on your Sharp AL1631 series copier press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "C" then the far left key (exposure mode) then the "C" key then the far left again.
So in other words C, far left, C, far left
If done correctly the display should go blank.
Then key in 24 as if you were going to make 24 copies.
Now press the "print" button
Now key in 7 as if you were making 7 copies
Now press the print button again.
You should now be getting flashing zero's on the display.
Turn the machine off then on again and your drum light should be gone.
Good Luck and Thank You for using Fixya.

Replace crum-light does not go out-will not reset sharp al1631 copier

Press # * C *.. the machine will go into diagnostics. then enter 24, then press start, then enter 06 and start. If it isnt 06, then press 07. I would do them both since the developer is just going to pop up with a message soon.

Sharp Al1631 unit won't copy; just spits out blank papers

check for empty toner... and if the laser lamp is dim or out... the laser lamp is the lamp that comes on when you copy from the glass table or through the document feeder

A loud clicking sound

This means that a gear is jammed or broken somewhere. Check for waste full and empty or drum waste roller and unblock the jammed toner inside that unit or check fuser gear if broken then replace it.

Sharp Al 1631 prints half a page

Sometimes the originals hesitate using the document feeder, which can cause the problem you are describing. Do you get the same rsults if you lay the original on the glass?

Sharp al1631 copier, copys are too Dim settings don't help ?

Check the toner supply, it may be running out of toner. Check the bottle or cartridge for correct install. Turn the machine on and let it warm up, Recheck the copy quality. If it is still light run a dozen blank copies, then a test copy if it is improving the toner is depleted and need to catch up, if it isn't there may be a problem with the toner add system.

Hope this is of some help.
