Question about Canon PIXMA iP4000 InkJet Photo Printer

1 Answer

Printing quality suddenly deteriorated

In spite of frequent nozzle cleaning and checks, very erratic colour printing -- severe stripes on page, top of page printing more or less OK, and then as one goes down the page the stripes begin and eventually colours are totally haywire....

The cartridges are totally OK.

Print heads problem?

Posted by on

  • brianjohn4 Dec 07, 2008

    Done deep cleans several times -- no joy. the bvlack seems to have come beck to normal, but the colours are chaotic still. Should I now take out all the cartridges and clean the heads with a solvent? Any views on the WD40 solution? Some seem to have tried it, and have found that it worked......

  • brianjohn4 Dec 09, 2008

    Tried the WD42 method. How long should one soak the heads for? and should one just leave the liquid there, or try to dry the heads off afterwards? I used cotton buds to remove the excess. Some of the heads seem OK now, but the cyan head id doing strange things -- after a clean or deep clean it's printing the test pattern OK,. but then on a real printing job it's printing in stripes -- a proper mess. Does this mean the heads are caput? How expensive is to replace the heads... or better just to get a new printer?

You could have printhead problems but I would offer that you do a deep clean and consider replacing cartridges with OEM

    Yeah the WD40 does work. But if you are ok with doing a head solvent cleaning .. I like using isopropl alcohol when I "soak"

    If you are using refilled cartridges I would ask that you try a set of "true" canon OEM cartridges.



    I am forever dealing with refilled cartridge problems with so many end users and the problems associated with refills that in the end, so often it seems, that they end up damaging the printer and/or the cartridges need more frequent replacing vs OEM.

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

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.
