A7 says that the scanner information in the eeprom is corrupted. The scanner is the wrong type. You will need a shop to do the eeprom clear in the diagnostic mode.

6A00 is AP position error.
First, make sure there is no paper jam anywhere in the machine.. look inside, rear, where the paper tray (output) is, etc to see if you find any shreds or torn paper that may have gotten stuck and you didn't see.Look carefully in the zone of Purge unit, using flashlight in the right side on printer.If this not help your printer need service.

Message unable to print 50


Machine Error 50 either means that there is a loose object inside the machine (usually piece of paper), or that there is a mechanical error which would need you to have the machine sent to service.

Epson R320 "General Error" message - unable to clear


If you are getting a 'carriage jam' error as soon as you turn on your Epson printer with no tasks in progress, then check for any piece of paper stuck in the carriage. Remove the paper carefully. If the paper tears, part of it might remain inside the paper path and damage the product.

Fix 'Carriage Jam' : Open Door, clear carriage jam,
and then press OK to continue' error message
Turn off the printer and open it to see where the paper is stuck.
Manually move the carriage toward the opposite side.
Check the paper path and remove any piece of paper or any other object that is stuck in the path.
Reconnect the power cord and turn on the printer.

Unable to clean message


When trying to use your Brother machine you get the message "Unable to _____". The blank may be the word Change, Print, Scan or Clean and these words may vary from model to model.
This message is a general message and will appear for different reasons. It often indicates a paper jam or a mechanical issue. Complete the following to determine the possible issue.

1.
Check for foreign objects, such as a clip or ripped paper, inside the machine.
Open the scanner cover by pulling up on the lower right corner of the cover. Look inside the machine and remove any foreign objects. If you see jammed paper or another item inside this area, gently pull it out and then close the scanner cover securely.

2. If the error continues to appear, the machine may have a mechanical problem.
If the error message continues to appear, the machine will need to be reset. Resetting the machine will erase all faxes in memory and the Fax Journal Report. However, there is a way to transfer faxes in memory and the Fax Journal Report to another fax machine to print them out. Do the following to transfer the data and reset the machine...


Thanks.

Pixma mp160 error message


Ok, my machine was also showing E3, and would NOT go away. My solution: turn the machine off, feed a piece of thick cardstock into the paper feed.Turn the machine on, let the machine take the paper almost all the way in, then pull it back all the way out against the feed. My E3 disappeared and has not yet returned!! Hope this helps David
