Has the printer been dropped? The cover has a tab that works a switch. either the tab is missing or broken or the switch is out of place or unplugged. you may have to remove the cover to find it.

SHARP MX-4071 Close Printer Cover - have opened and closed all covers but still cannot function. Any ideas?

If you have opened and closed all covers on your Sharp MX-4071 printer but are still receiving a "Close Printer Cover" error message, there may be a few possible reasons why this is happening. Here are some troubleshooting steps you can take:
  1. Check for any paper jams: Open all covers and inspect for any paper jams or debris that may be obstructing the printer's internal components. Clear any jams or debris that you find and ensure that there are no obstructions left inside the printer.
  2. Check the covers and sensors: Make sure that all covers are properly aligned and closed securely. Check the covers for any damage or signs of wear and tear that may be preventing them from closing correctly. Also, inspect the sensors that detect the covers to ensure that they are not damaged or obstructed.
  3. Reset the printer: Power off the printer, unplug it from the power source, and wait for about 30 seconds before plugging it back in and turning it on again. This will reset the printer and may resolve the issue.
  4. Update the printer firmware: Check if there are any available firmware updates for your Sharp MX-4071 printer and install them. Firmware updates can sometimes fix bugs and errors that may be causing the "Close Printer Cover" message to appear.
If none of these steps resolve the issue, you may need to contact Sharp support or a qualified technician for further assistance. They can diagnose the problem and determine if there are any hardware issues that need to be addressed.

When i turn on the printer i get a message saying error code 6500, the main carriage doesn't move at all, no response at all, all can get is the alternate blinking of LED's 20 times both blue and orange

First try this:

Reset the printer:

1. Turn the printer off with the Power button (if available).

2. Disconnect the data cable from the printer.

3. Unplug the printer's power cord for approximately 10 minutes, and then plug it back in.

4. Turn the printer back on. If this works you're done, if not try the next step.

1. After confirming that the printer is powered on, open the paper output tray.

2. Open the top cover and wait until the print head moves to the center.

3. Open the inner cover and check that ink tanks are properly seated.

4. Properly seated

5. Press down on each ink tank until a click is heard.

6. Close the inner cover and top cover.

My 8250 printer displays error code 0xc18a020a

Solution ....ink System Failure...error 0xc..........

These instructions worked very well for me. If you follow the same instructions exactly,it should work for you too.

1) If you are looking at the printer FROM THE FRONT, remove the right hand side cover. On most HP printers, there are 2-3 tabs on top that will either pop out with a screwdriver under the top cover, or can be removed with screws. Make sure you have the printer powered off and UNPLUGGED.

2) On the front, bottom, right is a separate piece of plastic that is attached to the side cover that should also be removed. Remove the plastic cover from the side at this point, and you should see a circuit board. The following link will show how to remove the printer cover: http://hpphotosmart8250.blogspot.com/

3) There are two ribbon-type connectors on the top [center] of the circuit board that are plugged in directly to the top, inserted towards the bottom of the printer. One is slightly wider than the other. Again, make sure your printer is powered off AND UNPLUGGED. Unplug both of these ribbons [this can be done without removal of the circuit board from the printer, just use care and maybe some forceps or hemostats to help with reinstalling later], and make sure they are not partially plugged in or touching the board.

4) Plug in, and turn back on the printer. A new Ink failure message should come up (the numbers will be different.) Click OK on this, then unplug the printer again.

5) Plug both of these ribbon cables back into their respective connectors. Plug in the printer and turn it on. It should start back up, and REINITIALIZE as if you just turned it on for the first time. [The printer will run for a long time pumping fresh ink through the print heads during initialization, so be sure you have cartridges that are fairly new/full.] The ink status will be correct, and no more ink system failure messages.

6) Put your printer back together...

  5. Plug the power back in. The unit will reinitialize and a message will appear to insert the cartridges.
  6. Open the top cover and reinsert the ink cartridges. Close the top cover. The message,

Hope this helps

Ink system has failed 0xc18a0206

This is easily fixed with the following key sequences. You do NOT have to open the printer and unplug a circuit board.

1) press * and # at the same time
2) press 1, 2, 3 and “support R0632M” should display
3) press > and “information menu” should display
4) press > and “configuration menu” should display
5) press OK and “hardware failure status” should display
6) press OK “failure status: clear”. Press OK to clear
7) press CANCEL
8) press CANCEL
9) press CANCEL
10) turn printer off, unplug power cord for 2 minutes, plug cord back in then turn printer back on.
NOTE: I did this and the fist time the error came back. Do the sequence again (as I did) and the error will be replaced with the usual print cartridge initialization screens. Print a test page to make sure.

Dell 922 "cover open" problem / error message

I had that problem too.

Unplug the printer.
Hold the printer cover open while you plug in the printer.
Then close the printer after it powers on.

It worked for me.

Top Cover Open

had same problem.  fixed this way: unplug power cable AND usb cable.  Replug both in.  physically remove both print cartidges.  put them back in.  this worked for me.


I guess you mean that the printer displays: No cart.

In that case open printer take all carts out, close cover and unplug machine from power for a minute. After reconnecting wait til machine demands carts. Open cover and reinsert carts as shown on display! Make sure that the carts are well positioned and the cart holder is clipped above the top cart cover! Run the cleaning cycle twice.
