How to clean Canon PIXMA print head flushing clogged print head

If an inkjet printer has not been used for some time and several print head deep cleaning has been done and it still does not print properly then the nozzles in the print head are blocked.
Inkjet printers need to be used frequently to prevent nozzles blocking with dried ink.
You need to replace the print head to get the printer functioning again.
But these print heads are expensive to replace, it may be better to buy a better and a later model printer for not much more costs.

cartridge also compatible with pro9500. inkoasis.com will get both original and compatible cartridges to you within a day or two. seem to work fine. much less expensive than originals. Staples will also get you a cartridge delivered directly to store for pickup even though they do not usually carry it.

Yeah, me too. I fiddled with cycling the power, removing and reinserting the tank, doing maintenance tasks like cleaning the jets, yadda, yadda, no dice. New full Canon tank displays empty. Boo.

I figured "What the heck, I'll try printing anyway" and sent a test page on plain paper. It warned me the tank was empty, then did a bunch of those cartridge moves it likes to do (you hear the carriage moving around cleaning or something). After like 90? seconds of cleaning noises, it figured out that the tank was full, the status went to full, and it printed the page fine.

So my advice is, try printing a page anyway.

remove the cartridge. unplug the printer. plug the printer back in. finally replace the cartridge using twice the force as before. J.

##100 TX Re-transmission of the procedure signal has been attempted the specified number of times, but failed.

try at another fax, if it fails you need to get your printer to service station.

It sounds like you are using aftermarket or refilled cartridges. To clear the sensors and nozzle, install new OEM cartridges, run deep cleaning a number of times (at least 3 times), and then the alignment utility.
Aftermarket/refilled cartridges do not always meet the manufacturer's specifications for quality. Try cartridges from LDproducts.com for your printer. I've never had a problem with their aftermarket cartridges.
Please rate this solution. Thanks.

Press the OK button.
- If paper is being fed at error occurrence, the
error is indicated after the paper is ejected.
- If the error occurs, the print head alignment
values are not changed.
- After exit from the error by the OK button,
the automatic print head alignment will not
be re-done.
The error will occur when the print head
alignment pattern is not printed due to no ink
or non-ejection of ink.
