Locked up AL-1642CS with blinking Drum Light

I had a blinking drum replace light and the machine would still not copy anything, it's suppose to copy until the light is on continuously. My drum counter is showing 016018 copies. All of the buttons on the consol are not funtioning. All I can do is turn the machine on and off and it goes through its warm up routine.
I also see a bunch of suggestions to reset the drum counter but like I said above the buttons are not functioning after the warm up period. I also don't see the buttons " * " and " # " on my key pad. Help! I've already purchased a new drum and TD cartridge.

Older Sharp AL copiers will go on working with the drum light blinking, but yours will not. Newer models do stop working when the drum reaches its limit. Now keep in mind that just as almost every copier in the market, these units count the copies they make in order to determine toner & drum life. So it is possible to reset the drum counter if you inspect the unit and see no markings or visible wear & tear. Also keep in mind that the toner & drum units have been the same for all AL units through time, so there are plenty of good replacements in the market (not recycled, but re-manufactured or brand-new compatibles).

As for your unit, if the drum is Sharp original or a good quality replacement, you should have to do nothing after installation, for the internal chip in the drum will tell the copier to reset the counter and begin working automatically. However if that is not the case, or should you want to reset the counter on your existing drum, this is the correct sequence to do so.

  1. Identify the buttons used for adjusting exposure (darker or lighter copies), amount of copies, clear copies and start copying.
  2. Now press the following sequence of buttons: [CLR], [EXPOSURE], [CLR], [EXPOSURE]
  3. Your unit should turn off the numbers in the panel.
  4. Now press 24 as if asking for 24 copies and press [START].
  5. Press 07 as if asking for 7 copies and press [START].
  6. Your unit should restart by itself and start working normally.
Be blessed.

My Sharp 1642cs says replace drum cartridge on the lcd. Even installing a brand oem drum cartridge. It will not function at all. How do i reset it?


Reset the drum count by pressing "Clear" then "Exposure Mode" then "Clear" then "Exposure Mode"
Exposure mode is far left key on panel. You need to do this fairly quickly so that the display goes blank.
Once display goes blank then key in 24 then press print, then key in 7 then press print. You should now be getting flashing 000
Turn machine off then on and light should be gone.
Short version: C,far left,C,far left,24,print,7,print

Locked up AL-1642CS with blinking Drum Light


the clear key may be stuck which seems to lock up your machine. The procedure to reset the drum lite is clear, auto (exposure setting), clear, auto when hit in a timely manner the display will go blank. Enter 24 then press the start key, then enter 07 and press the start key again. If you can't get the keys to work the circuit board may have cold solder joints.
Good luck

Did you replace the drum with a Sharp brand drum? I recently replaced a drum in my Sharp AL-1642CS, the replacement drum fits ok, and the lights you describe are gone now, but it does make an annoying noise that is new. I wish I would have spent the money to get a Sharp drum, then you can call them directly for support. When I have called them they have been very helpful.
