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.

Re: Locked up AL-1642CS with blinking Drum Light
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.
Identify the buttons used for adjusting exposure (darker or lighter copies), amount of copies, clear copies and start copying.
Now press the following sequence of buttons: [CLR], [EXPOSURE], [CLR], [EXPOSURE]
Your unit should turn off the numbers in the panel.
Now press 24 as if asking for 24 copies and press [START].
Press 07 as if asking for 7 copies and press [START].
Your unit should restart by itself and start working normally.

To reset the photoconductor drum counter, press and hold the Cancel button on the printer until all lights flash in sequence. You can clear the Replace photoconductor message only when the imaging drum has been replaced. For more information on how to replace the drum, see the User's Guide.:
1. The Drum LED blinks if the drum unit is near the end of its life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one. 2. The Drum LED continues to blink if the drum counter was not reset when you replaced the drum. To reset the drum follow the instructions below: a. Open the front cover of the printer. b. Press and hold down the white button for about 4 seconds until all the LEDs light up. Once all 4 LEDs are lit, release the button. c. Close
You are not supposed to replace the drum until it says"replace drum"
Not when it is saying "replace drum soon."...you have prematurely blown fuse in the cartridge so now it will not reset.
Try the following...
Press...PROGRAM,*,*,I(That is Capital I), then ENTER.(SHOULD RESET IT.)
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.
Sounds like it's time for a new drum but, here's the reset procedure that should make the drum light go off and allow printing.
Make sure the machine is turned on and the drum light is blinking. Press and hold the "GO" button for 4 seconds (approx.) until all four lights are lit. When all four are lit, release the "GO" button. Make sure the drum light is off now. The drum is now reset.
THIS WILL NOT IMPROVE THE QUALITY OF PRINT as the drum will need to be replaced in order to do that but it will allow you to continue using the drum until it reaches and unacceptable quality.
