Question about Canon PIXMA MP780 All-In-One InkJet Printer

2 Answers

Help needed with printer.

The computer was sending a message that there was a paper jam which I managed to fix. I now get the message that the computer is off line. (I have had both the computer and the printer down whilst getting the room carpeted, but thought I had reconnected them correctly.) I took the printer to the local service agent but was advised that it would cost me $33 to book it in and from 5 -7 days before I could collect it. This was when I had the paper jam. I didn't want to wait that long and as mentioned I managed to fix the paper jam. I've got the printer connected to the power line and also to the computer. The compute is connected to the modem. What can I do to get the printer back on line?

Re: Help needed with printer.

Go to your printers folder, normally (Start> Printers & Faxes) on menu or click on control panel and open Priters & Faxes Icon and see if your printer is in there. When you re-connected your printer you may have put it in a different usb port than previously, sometimes the pc assumes its a different printer. If the printer icon is in there you should be able to right click on it and an option to make printer go online or untick 'use printer offline'. If all fails, remove/uninstall the printer driver, dis-connect your printer, put in your printer driver cd (Best to install drivers first always) follow setup and connect your printer via any usb port and windows should find it and install the drivers automatically. Good luck.

Re: Help needed with printer.

Sorry for the delay in responding to this problem, recently i came accross similar problem and got a good resolution for the same. First try and print a test page from the printer .... if its an Hp printer the following link should help make sure that the printer test page prints fine. Now if the printer is connected through a USB cable, try and disconnect the cable from both ends ( from the back of the computer and from the back of the printer ) plug it back in. you might get a Found new Hardware popup at the right hand side bottom cornner, if you do then wait for 2 or 3 minutes. It might ask you to inser the installtion cd, so please do so. That should work for you. Try a different usb port from the back of your computer. If it still doesn't work, go to the printers and faxes folder under the control panel and still the printer icon is showing offline, right click on the printer icon click on cancel all documents and then again right click on the printer icon and delete the printer icon. insert the printer installtion cd and it will automatically install all the printer drivers automatically. I got this resolution from *** , those people are excellent.

SOURCE: canon mp180 paper jammed

I finally fixed the problem by running two sheets of heavy card stock through at the same time. With the machine off, I positioned the two sheets in the feeder so that they would be pulled in when the printer was turned on. When I turned on the printer, it drew the two sheets through and I guess this reset the paper sensor. I previously found that only one sheet at a time did't work.
I found this solution posted by JsamJr answering another question but it worked for me. pushing the card in and then removing it and pressing ok worked

SOURCE: 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

SOURCE: Printer says clear paper jam then press reset

Could there possibly be:

A) Paper jammed internally: Power Off. Open the cover and remove the paper or scrap carefully. Do not touch the internal printer parts. Close the cover. Power on.

B) Foreign objects in printer: Power Off. Open the paper support and confirm that there is no foreign material in the auto sheet feeder. (If so, remove it by hand or with tweezers). Open the front cover and confirm that there is no foreign material in the unit. Avoid touching the inner workings of the machine.

C) Reset the printer:

1. Turn the printer off with the Power button

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. Attach data cable.

4. Turn the printer back on.

If all of these suggestions fail, your iP1600 may require repair service. Please note: With the suggested retail price of $29.99 USD, repair does not seem cost effective - you could just go out and purchase a new printer.

Computer says paper jam in printer but printer will make copies

Welcome to the ever popular-widely experienced world of:
YES! That wonderful world where unbeknownst to you but knownst to us (OK I watch Spaceballs WAY TOO MUCH) When you are sending a print job, somehow the paper size setting has been changed. Either in the printer itself, or in the print properties settings in your OS.
Double-check those paper size settings and try to print. If it still happens, try resetting the print settings in the printer back to factory default. Make sure you print out the printer configuration before resetting in case you need to reinstall those settings.

6110xi paper jam, or something worse?

Actually, the "paper jam" message can be displayed due to a variety of jam locations and other causes. Starting by looking in the back of the printer is a good first step, but you can have a jam in the front or even in the automatic document feeder (although that one should be apparent because it's sticking out the front end. has a web page that goes into a lot of detail about where to look for a paper jam and what other conditions in your product might cause such a message to occur. The solutions are available as well. Take a look here:

Paper Jam

hi y'all -

you share a frustrating problem... error message but no apparent error (jam)! it's one that's common to many models of printers and the result of many different causes.

I've seen it when I've printed on cheaper paper, or different (lower) grades with odd surface finishes. the sensors get dirty, or the printer/computer 'thinks' there's paper stuck where none exists. I've opened/closed paper trays 2-3 times and rolled feed rollers around multiple times, then closed printer paper drawers only to have the 3rd time of doing the exact same steps be the time it cleared the error message.

there are often very tiny pieces of paper stuck in weird places in the paper path in printers, too. if you did have a jam before the message started, is every little scrap of the page accounted for? there are also hard to get to places to find paper scraps in larger printers, but I'm going to assume you're all talking about home printers.

here are a few general HP support links you may find helpful for future paper jam messages for this model of printer.

this link is for general info for this model:

here's a link addressing paper jams in general:

and here's one on cleaning your printer:

hope this helps a little bit for future refs. remember that using good paper helps print quality and lessens printing problems. also, when you take a stuck page out of a printer, doing so gently will help ensure little scraps of paper do not tear off paper edges and get stuck in weird spots. it some times helps to gently, manually, roll the feed rollers a full turn around in the printer, too. patience pays! -JW50

Error Light does not turn off!

Hi, it sounds like your printer experiencing a hardware failure thats why the error light still on. The sensor that detects paper jam or any obstruction might be defective. Aside from that your printer may also experienced a motion carriage error. You can to power cycle the printer & check ink cartridge. if the error still present your printer might be needed to be send to the nearest Epson Service center.

Paper jams can be real or false. The all-in-one may report a paper jam when there is not any jammed paper, however, the solution to a real paper jam or a false paper jam is the same. Up-grading the printer firmware could also fix this kind of issue, however I would appreciate if you try the steps below before you up-grade the printer firmware.
To fix the paper Jam errors please try the following steps:
1. Confirm that no foreign materials are inside the machine.
2. Confirm that usable paper is set.
3. Confirm that the paper is set properly.
4. Confirm that recommended paper is used, and the number of sheets set does not exceed the required limit.
5. Disconnect the printer power cord as well as the printer cable form the printer.
6. Turn the printer upside down and shake the printer in order to remove any obstacle which is stuck inside the printer causing the paper jam error.
Open the printer cover and remove the cartridges and check carefully if there is any small piece of paper which is stuck inside, if so carefully remove it.
7. Disconnect the printer power cord and press and hold the power button on the printer for about 15 to 20 seconds( this will release the flee power) and reconnect the printer and check.

If the above mentioned steps do not fix the issue please up-grade the printer firmware form the web site. However make sure that you do not turn off either your printer or computer when you are downloading and installing the printer firmware.
Alternately you can also try to download the and install the printer drives form the support site if the paper jam message is being displayed on the computer’s screen but not on the printer’s LCD screen.

Should you require any further assistance regarding the printer or even any other computer related issue please feel free to contact me I will be more than glad to assist you.
