Hello,

Among the most common problems with any make of copier are paper jams. A copier will jam for any number of reasons: It’s dirty, the wrong paper type is being used, or the rollers on the copier that feed the paper through its pathway are worn down. While cleaning the copier periodically and using the correct paper type are easy fixes, also, the roller may need replacement, the roller is a difficult task to replace, i will advice you get a repairman to help with that.

Take care.

In most cases, it's easier to pull the jammed paper if you turn the printer OFF and the pull the paper VERY SLOWLY

Okay so this may not help you now, but I just got a hand me down D780. After much frustration and research here's the solution that I was able to work with. It isn't perfect; but it's something....So here are the steps for network shared installation; assuming your D780 is installed on an old xp desktop and you're using a Win-7 laptop. If you're using the printer directly on your Win-7 machine, just use the local printer installation after the XP mode has been installed. 1) You'll have to install WinXP mode on Win-7 using the steps listed on this link. If you have a genuine Win-7 copy installed, this download and installation is free, courtesy Microsoft.http://windows.microsoft.com/en-us/windows7/products/features/windows-xp-mode2) After installation, you'll have to change network settings for your virtual pc. This step is necessary if you want to be on the same home network and want to see the printer! Never mind if you don't understand this logic. Just follow the steps and you'll do just fine. To change the network settings in vPC: click Tools; click Settings; select Network from left; then for Adapter 1 choose the actual network adapter connected to your router (simply put: select the wireless adapter or wired adapter you're using to connect to your actual router or home network. You can find that from Change Adapter Settings in Network and Sharing.) Click Ok.3) Now add the printer as local or networked following your usual XP steps. You should be able to see the printer. If not, open a command prompt window, check your ip to make sure you're on same network. If not, or if you don't know how to do that, just type in ipconfig /release enter and then ipconfig /renew enter. Try to connect to the shared printer by pinging the ip of the host computer. If the ping works, you should be able to see the printer then.Connect printer and use in XP mode. Not the best solution, I know. But it's free and at least lets you print from your laptop, given the circumstances.

Reinstall your Imageclass D780 driver due to your original driver is corrupted.

This is a fuser error you need to replace the fuser. you need to remove the covers on the left side. Then look under the black plastic sheet. You will see the fuser. You need a very short No 2 phlips head screw driver like 1 inch long. remove the screws and un-plug it. It will slip out. Get a new fuser and install. Thank you, Steven

You can manually lift the cover and remove it.

Go to the Canon website - www.usa.canon.com and search for the driver there.

If you cannot find it, then more than likely Canon has chosen not to support the printer on this operating system. Your next best option would be to look for a generic Canon driver from within the Windows Driver list.

the steps are posted on the reference guide found in the link below from Canon

You may just have a bad cartridge. Replace it.

Pick up rollers dirty or the shaft is miss alighned and there is a fix for this where cannon has a part number for it and it is FG6-9554-000 which is called the Retainer shaft maintanance kit.

Drum Memory
Make about 5 to 10 prints; then, leave the machine in the office environment (normal temperature/humidity conditions)

* This symptom is noticeable in a low temperature/ humidity environment, and is absent under normal environmental conditions.

* This symptom occurs in keeping with the primary charging roller rotation (38 mm).

I will recommend that you put your printer power off for 2 seconds and remove the tray again and reset it back accordingly and put the power on again and try to fax. Make sure you turn. Let me know how it went.
