I have a Lexmark All-in-One X5150 printer. All of a sudden I started geting a connumication errors. I fixed these a couple of times by rebooting the computer. Now I am getting cartirdge errors (50C with a message to look at my user guide). I have an old color cartridge that I have not changed in years since we only do black and white prints. I tried the suggested fix in the User Manual which did not solve the problem. I got a new black cartridge and it did not solve the provlem. I tried cleaning the contacts in the printer cartridge buckets and on the cartirdges and that did not work. I am out of ideas. Can you help me?

Error: " Hardware Error 0504 " on the LCD Display
When you try to run the Clean option from the Ink Cartridge menu, the following message may appear: Hardware Error 0504. To resolve this issue:
Take both cartridges out of the printer.
Switch off the printer using the power button.
Disconnect the power cable from the back of the Lexmark X5150.
Leave the power cable disconnected for 30 seconds.
Reconnect the power cable and switch the printer on again.
Reinstall the cartridges. (Follow the instructions on the LCD screen or refer to the following document: http://support.lexmark.com/index?page=techlibraryKB&linkSelected=node2^subnode0&channel=techlibrarykbchannels&locale=EN&userlocale=EN_UK
The 0502 error code can be caused by either faulty cartridge or a dislodged encoder strip (transparent strip) in the cartridge area. Refer to this article in the Lexmark website on Error 0502 on the Lexmark X5130/X5150/X5190 Pro LCD Display. This will help you determine and resolve the problem. Thanks.
After months of use, your printer might get the habit of stopping in the middle of a page and showing "Hardware Error 0502" on the LCD display. If you leave the printer alone for a while, it might start printing again. Then again, it might not. Pretty annoying.
The Lexmark support site will let you power off, remove the power cord for 30 seconds, take out the cartridges and fiddle with some encoder strip. This whole procedure might take you up to 30 minutes and it will not help (been there, done that).
On the multi function machine seems to be a coating on the metal rod that the cartridges travel on. Just wipe this rod with a kleenex and the problem seems to go away. Somehow it presents a drag on the cartridges and causes an error.
Clean that with a paper towel. The towel will be black from the ink residue, but you will be able to print again.
