Cannot scan with Canon MX870. Error code 5,145,61 Windows XP Wired LAN connected printer and laptop reinstalled Print/scan/fax S/W - still no scanning. Printing OK. ???

My solution was to open the MP Navigator application and then click the preferences at the top right. There is a product name dropdown. In my case the incorrect MAC address was chosen (denoted by "Network:XXXXXXXXXXX"). Once I chose the other address it worked perfectly.

Many printers will not scan over a network, even when they are supposed to. Try connect to it with a standard USB cable and scan to PC directly. If that doesn't work - you have probably got a faulty scanner.

If the scanner works OK directly to a printer, then your issue is either LAN/WLAN bandwidth or an unstable IP address. Try fixing the IP Address rather than running DHCP address allocation eg set it at 192.168.x.150 where x is the range value for your network. Then set the printer port address on your devices to the same values and try again.

Get message "communication error has

I would go inside the devices and printers and preferences and see if there are any documents pending. Erase those. Check with your little icon on the desktop and check printer status or you could even go to the extreme of deleting canon in add and remove and reinstall from the canon website. Obviously with windows 7 if you just plug in you will get driver installed but printer runs much more smoothly if you first download the software package from and then link up wirelessly.

But first check that a document isn't pending printing.

I'm getting "A communication error has occurred."

Turn off your mobile phone or put it in flight mode. I had the same problem for months and once I figured this out it hasn't happened since.

here is what cannon says " "
they want you to try resetting memory

  1. On the operator panel, press the <ON> button. (The display will go blank.)

    Note: It may be necessary to unplug the power cord if pressing the ON button does not shut off the printer.

  2. Wait approximately ten seconds and then press the <ON> button again.

  3. Wait until the device has completed its cycling process

    Note: It may be necessary to unplug the power cord and retry if the above steps do not clear the error.
these steps seem very simple and infective. my advice, check for a paper jam internal paper bits or a ripped piece of paper 41that is blocking internal sensors and indicating a printed page is stuck in the tray. also check the print cartridge did not dislodge during printing. it dose happen and they sometimes need to just be reseated to resume printing. their will also be issues with the units not working properly due to manufacturing defects. but the printer has a fairly dignified rating, remember all in ones are more complicated and theirs far more that can go wrong with them. so trouble shooting those things first will help in figuring out why it is not working. sometimes unplugging the printer from the wall and pressing the power button to try and bleed off excess voltage from the capacitors inside will get the unit to reset faster. but the printer sounds like it is displaying a internal fault code. see their manual downloadable here
