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

1 Answer

Scanner Problems Hi I purchased a Canon PIXMA MP780 last year and all has been fine. Then the other day I was doing a 6 page batch scan and the 1st page went through fine the second page stopped half way through and did not finish the scan, since then it has not worked properly with the scanner. I have installed the software on my laptop and it works just fine. The problem is i need it to work with my main pc, which it has been doing until this problem. I have tried used the CD that came with it and also downloaded the software from Canon. I have uninstalled all the software and re installed, making sure it was not connected until after it said to connect, I have repeated this several times but cannot get it to work with the pc again. The printer will work. It does see the scanner and attempts to scan but the most it manages to get it is to 14%. Very frustrated. Thanks in advance

Do I need a new scanner bulb?

It sounds very much as if the scanner is faulty/failed. The warming-up phase is to ensure that the scanner lamps output is steady, making for consistent scans. Usually this is just a simple timing circuit.
Having once tried to fix a broken flatbed scanner myself, I found that obtaining the correct replacement lamp for it was impossible - I think inkjet printers and scanners are considered "consumable". You may be better off buying a new printer. Alternatively, if it keeps producing good prints, consider buying a separate scanner. HTH

Right now, the scanner bar is stuck to the far right and it makes a loud noise like gears slipping. But I would also like a copy of the "Service and Repair Manual" for any future problems.

Hi rksde,

First of all, thank you for purchasing the service/repair manual of Canon Pixma MP780.

Please email me at, manual has 132 pages, it can't be uploaded here.
Again, thank you so much!

Canon pixma mp780 auto feed does not print

You probably need a new printhead, but that problem cann also be caused by the purge or cleaning station not working properly. If you do a cleaning cycle with no carts. and the little pads in the printhead come back with no ink on them then the purge is working and you need a new printhead.

Blurry Scanning/Copying

Are you scanning both black and white and color the same way? The ADF (automatic document feeder) uses a different scanning area than when you place the document on the scanning glass. If you open the scanner cover, look to the left of the main scanner glass to the narrow strip used for the ADF. Make sure this narrow strip is clean -- no ink or white-out or scratches. This can make your copies look dirty or smudged.
