When trying to print iPad says that printer is paused


Clean the print heads at least four times in a row, without doing anything else in between... don't make a test, don't restart it; just clean the heads.

What difference did that make, please?

You need to replace the print heads based on the color which missed.

You have I am sorry to say a blocked print head. You would have to fit a new one but only a trained engineer could do it as the head is not a separate part and its a pig of a job if you have never done one. Take a tip and take it to the tip and buy a new one. PS, part number is LK2179001

My CaNON ip90 PRINTER SAYS "ERROR" WHEN TRYING TO


Hi there maximum time we found it is a the head problem. The print head is what the cartridges sit in inside of the printer. For resolve the problem please follow these.
Open the printer and wait for the carriage to slide over. Some how if its not come then Unplug the printer & Manually slide the carriage. Now Remove the ink cartridges from the print head & Use wet warm cotton swab or use alcohol to thoroughly clean the print head. Repeat this until there is no ink residue coming off on the cotton swab. After finished it make the head dry then fix it back. Now Try to print something now If that does not work then follow the next step.
Remove the printer data cable & restart the PC & printer. Then fit back the data cable & turn on the printer. Hope that's start working , if no luck then Uninstall the printer driver & restart the PC & Printer both again. Now install the driver of the printer and connect it with PC ,Turn on printer & go for a test print from the printer preference. Thanks & waiting for your reply.

Remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and connect the Printer to be detected and installed. Check printer properties to see the ink levels.
Use head cleaning before a test is taken . It is possible that the head is not reacting to the need of the command , can be an issue with ink drying , can also be poor ink cartridge contacts, tighten the cartriges onto the slots.

Printer printing in with stripes


You can try to perform a power purge, do it by the following:
  • Enter maintenance mode. Either with starting your machine with Menu button down, or by pressing Menu, 2, 8, 6, 4 quickly. The fax/copy/scan buttons should flash/be lit.
  • Press 7, 6.
  • Press 3, the machine should now say something like "POWER_P" or "P_PURGE"
  • Press Mono/Black start, the machine should now say "cleaning".
  • When it's done, the display should say Maintenance, and you can leave this service mode by typing 9, 9.
You can now try printing a test page again, the result should hopefully be better.
Be noted however, that this purge takes ink from your cartridges, but it's more likely to solve the issue then just trying to do more "regular cleaning".

I was working on the Pixma mx850 for 3 weeks now. I have found that you need to reset the using back to factory default. On the display look for the "printer head" cleaning and alignment. Go through the steps that it gives you for printer head cleaning. Print a test page. have you tried to copy in "black/whte" and not color? that will use the large black and not the small black cartrdge. Try a couple of black circles in "paint" if your running windows XP. make a test page of your own and print it.
