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

1 Answer

Scanning problem Sometimes scanning fails completely, sometimes scanning begins but is not completed. There is no indication that scanning has failed, it just stops. The portion of the image that is scanned goes into memory (in use/memory light comes on) - only way to get rid of it is to switch power off MP780 and try again. At present time, unable to successfully complete a scan of anything. Help please.

A E Code on my Sharp SF 2025 copier, what's this?

H4, not heating up, replace fuser unit complete or work with hivolts and replace an expensive and tricky lamp/thermister . wont be cheap.

. Here use the reset for it first, sometimes power surges can just flip them out but most times will just reappear shortly after reset, indicating the want of a working fuser assembly

Fuser (not fuse) is the hot bit with rollers at paper exit if code fails it needs to be replaced, wont come cheap no matter how you approach it

C-Exposure key-C-Exposure key-14-copy key to clear ... but it will come back I bet...

Why are there black lines down the centre of my faxes

This can be due to some dust on the scanning apparatus. Simply try blowing it out. If it will not help, it is probably defective, however it rarely fails completely. On scanners it sometimes does yellow stripes. It usually comes with older devices.

Scanning stops unexpectedly. Message reads "The wizard did not successfully complete copying your pictures because the process was cancelled." It was not cancelled. Nothing was touching the mouse or...

This is a software issue. Somehow the applicaiton drivers are failing to complete the routing. This indicates corrupt printer application files.

You will need to uninstall the printer software, restart the computer then re-install the software.

Kyocera mita j11 error code

On most Kyocera Mita copiers a J-11 code indicates a possible paper jam when paper is being fed from drawer #1, but sometimes a J-11 will be indicated when the paper fails to feed from the drawer. Check the paper stops and paper guides in the drawer and make sure that they are flush against the paper, also cleaning the paper feed and pick-up rollers with a rag dampened with just plain water will help sometimes unless the rollers are completely worn out. If all this doesn't help you may have a paper feed clutch or lift motor that has failed.

Epson DX6000 scanner problem

If it's a new printer, try changing the USB printer cable. Sometimes one of the wires just gives out and doesn't communicate properly between the printer and your PC. Hope this helps.
