Question about Canon SmartBase MP730 All-In-One InkJet Printer

Canon MP 730 prints wrong color tones

My Canon MP 730 has worked just great up until a couple of weeks ago. Suddenly it has started printing color fonts and photos with the wrong colors - this affects all applications on my pc. Example in MS Word 2003 the red font (on the screen) prints purple. An Adobe Photoshop tiff or jpg that looks perfect on screen now prints with green or red tones. it seems as if the printer icc - color profile has changed. How do I reset the profile. I've tried downloading & updating the drivers - no change.

    I have the same problem. Worked great until a few weeks ago. Still prints fine but colors are way off. I only use genuine Canon ink and they are all full. Any solutions out there?

    I use only Canon ink and recently it started printing the wrong color. Sometimes Yellow is partly Yellow, sometimes other colors. I am afraid to waste ink printing a photo as I never know if it will come out with the correct colors? What's happening???

    Same here. Prints greens as purples. Very annoying. I tried everything with ICM profiles etc... but it is the same. I wonder if the yellow is no longer printing. I don't know.......

    I get to join the wrong color club also. Red is printing out as green, green as bright yellow, and light brown and light yellow....4 years of reliable service, than all of sudden the colors are wrong. Ran diagnostics, cleaned heads and joy.

    Same thing for me. I only use genuine Canon ink and it started printing the wrong color. Just now, it printed brown instead of orange. Not even close! I agree I don't want to print things because it will waste the ink if it doesn't come out in the right color. C'mon Canon - tell us how to fix this!

I was having a similar problem-- what was happening was the print cartridge head seemed to be letting the colors leak into each other. (the science behind this is beyond me!)-- I noticed that instead of being cyan/magenta/yellow, my yellow cartridge had actually turned green, magenta was picking up blue and was turning purple, etc etc. I ended up replacing the printer's printhead and all the color cartridges and then it worked.
You can order printheads online.
Not sure if this fixes the original reason why they got all mixed up in the first place-- if the printer will continue to allow the print head to leak the colors into each other-- but hopefully that's a fixit!

My Epson WF-3640 is printing with gaps in the text. How do I fix this issue?

Make sure you should remove shipping tape from the ink cartridge. These taps are used to protect printer during shipping but you have to remove it before starting printing. Beacuse these taps prevent the ink to entering in print head. If you will not found shipping tape in your printer then there is terr off strip, remove it. The tear off strip seals the the vent holes on the top of the cartridge to prevent it from drying out on the shelf or during shipping.
After ensuring that the shipping tape has been removed, run the printer's "Head Cleaning" utility to prime the cartridge, then print a test page.

Prinnter not printing but showing 'put custom in manual tray'

There is still a print job in the queue. Place a sheet so it prints or kill the job.

Open Printers and Faxes. Open printer. Highlight jobs and Right click > Cancel, or Documents > Cancel.
For those stubborn jobs, Right click My Computer > Manage. Choose Services and Applications > Services > Print Spooler. Right click and stop. Then start. This may have to be done from the Print Server if it's network printer. Contact IT to kill.

Laser printer makes light clicking noise when idle

When idle is potentially the fuser unit, after heating and cooling. However the print quality issue associated with the clicking sound could indicate an electrical issue. The HVPS maybe faulty causing the print quality issue (due to dependant parts) and the electrical click. In any case I would recommend calling Brother and finding the nearest authorised service agent.
