My lexmark z1320 will not switch on right. the light just keeps flashing and my computer not picking up device. it was working 24hrs before and no one has used it since. can you please tell me what the...

The flashing of the lights could mean paper jam, alignment problem, ink level low warning. Try to disconnect the printer from your computer. Remove the sheets of paper from the feeder. Open the printer cover and remove the cartridges. Close the cover. Unplug and replug the printer into the power source to reset it. When the printer turns on, open the printer cover and reinsert the cartridges. Close the printer cover. Reconnect the printer into your computer. Make sure ink levels are substantial for printing. Try to print again.

Problem with my Canon Pixma MP500

Try a hard reset first: Unplug the printer from power source and PC, wait about 5 minutes and replug. Should the issue recur, then the cover sensor is probably faulty. That is the reason you are getting this error repeatedly. The only solution is to send the printer in for servicing and get the sensor repaired/replaced.

In any case, here are the steps to close the inner cover:

1. Press the Open Button (1) to open the Paper Output Tray (2).
2. Raise the Scanning Unit until it stops.

3. Close the Inner Cover

4. Now close the Scanning Unit.

You can also try reinstalling the printer software along with any patches, updates, etc from the Canon website. Make sure you uninstall the existing software first though..

If neither works, then its time to take the printer in for servicing. You could try to contact them by phone first:
  • Toll-free live technical support** Monday through Friday 10:00 AM ET to 10:00 PM ET (excluding holidays) at 1-800-828-4040
  • The location of the ASF nearest you for carry-in service at 1-800-828-4040
  • Toll-free TDD Support Line for the Hearing Impaired Monday - Saturday (excluding holidays) at 1-866-251-3752
  • Technical Support for Customers in Canada at 1-800-OK-CANON
Hope that helps!

Cover open sensor is knocked off the switch assembly - Please show and tell me how I can repair it.

Open the printer cover and remove the cartridges. Close the cover. Unplug and replug the printer into the power outlet to reset it. When the printer turns on, reinsert the cartridges. Make sure the cartridges are properly inserted in the carrier and the lids snap in.

I keep getting the close the cd/dvd guide

When you flip the main cover up, and flip the CD/DVD tray down, look at the cartridge color guide label (the colored dots). See the LIGHT CYAN dot? Directly across from that dot around underneath the gray cover is supposed to be a little plastic fin. That fin pushes the sensor switch in the CD/DVD tray to let the printer know if it is open or closed. If it breaks off, then the printer always thinks the tray is open. If it's broken off, you will have to either stick a toothpick or something into the switch, or glue a new thin piece of plastic in its place.

I changed the ink in my Lexmark 3400 printer and I keep getting an error message "cover open" and it's not open. I tried everything....unloading the software then reloading the software, shutting it off...

The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.

This can happen if the lever on the cover open sensor is knocked off the switch assembly.

Top cover does not seem to close, and keeps stating that its open, when it is closed.

Your printers top cover is closed. Its generating error just because of faulty sensor. You require to change the sensor. If you are assured that you can do it yourself with our guidence then kindly comment back, or else simply take it to a technician.

Replace Panel in Xerox 8550 Color Printer - Close Exit Cover

Open that cover and look in the frame of the machine for an opening. Then look on the upper cover. There is an interlock switch on the machine. The plastic tab on the upper cover often times breaks off and will not actuate the switch, giving you that message.
You can fix it by gluing a paper clip onto the cover. Or call 1-800-835-6100 and order a new cover.

Cover open message and there are no covers open

On Many of these printers, when you recieve this message chances are you either have a "BENT" limit switch sensor or the Tap on the Cover is "Broken or Broke off",
First Step open each cover and close them again sometimes the limit switch isn't being hit correctly by the door Tab

Second- as you open the covers their are tabs that must hit these sensors- make sure their not broken or bent.

Start their and tell me if these resolves the problem chance are the tabs are not hitting the switches correctly and not telling the samsung printer that the covers are closed.

Brother DCP-7020

Props to Profjake. I followed his advice and problem solved! Here is what I found out.

I had the "Back door open" error on the LCD panel. There is a "interupter" type of sensor that detects if the back door is open or closed. When the back door is closed a lever is pushed forward and blocks the interupt module. The lever that blocks the sensor was not reqching the sensor horizontally - it was too far to the left. The lever on the far right is part of a 6" rod that goes across the middle of the paper path. The rod had jumped out of it's "home" position to the left and it was bowed a little bit. I carefully re-seated the rod to by gently lifting it and moving it to the right into a slot 1/8" from where I found it. The error cleared immediately. The was most likely caused by removing a paper jam.

Once again props to Profjake as his advice led me to the solution.

Hu said that!
