Canon MP510 : ATT Art

From: Sparky on 1 May 2010 13:34 You were good enough to reply to my post last week , I wonder if I could trouble you again ? I posted regarding removing the carts so that I could clean the print head , which is missing black. I was concerned they'd be marked as empty by the printer on reinsertion ( they weren't). I cleaned the head , ran a test print , and all seemed OK. A day or so later , I tried to print again using the Plain Paper settings and the page came out completely ' clean ' . No a speck of black ink...it was as though there was no black cart installed. If I remember correctly , you stated that there were 2 sets of nozzles and that's why I could print on photo paper settings and not plain ? I did another clean , and used compress air to blow through , but no luck. On plain paper the page is blank . I swapped for a new cart with the same result ( except this time , when I put the original back in , it was marked as EMPTY ( very annoying ) , so I disabled the Status Monitor. For the past few days I've been looking for replacements , but I don't really see anything that appeals. I'm reluctant to go with another Canon , HP seems the most likely candidate right now , but their carts are way too expensive , and the only 3rd party alternatives seem to involve re filling ? I'd rather use a machine that has replacement 3rd party carts available. That appears to be Epson or Brother ? I've had Epson before , and experienced the block print head syndrome. Not keen to go down THAT avenue again. From what I've read , the Brother machines seem quite ' reliable ' even if the print quality is somewhat lacking ( I don't print photos so that's really not an issue...) Anyway , what I'd REALLY like to know is there anything I can do to repair the plain paper printing on the Canon ? My guess is probably no , but before it becomes a donation to the recyclers , I thought I'd ask. Many thanks for your input. Sparky.

Probably a bit late now, but I have found that applying external pressure to a printhead seems to be certain death. I've trashed 2 epsons by attempting to clear a partly blocked head by squirting/blowing through it

I've trashed 2 epsons > by attempting to clear a partly blocked head by squirting/blowing > through it While your comments are for the most part correct with Epson heads, Canon's technology is quite different, and sometimes the head can be safely unblocked via compressed air. Epson heads use piezoelectric actuators and a complex channel and pump system which requires creating a laminated head which, if the nozzles are blocked can cause the head to delaminate if pressurized fluids are placed through the ink delivery system. Canon heads use thermal expansion of the ink column to push ink out of the head, and it is more straight forward. However, all thermal heads eventually degrade and fail electronically, due to this continual heading and colling process. Art

I don;t recall if you requested my Canon cleaning manual or not, which has a few suggestions on head cleaning beyond compressed air. If not, you can request a copy by emailing me at: e-printerhelp(at)mvps(dot)org (at) = @ (dot) = . The only other thing I can suggest is that it is possible a bad connection between the printer and print head has developed for the plain paper nozzle set. Make sure the contacts are clean, and make good contact with the printer side. Before giving up on your printer, consider buying a replacement head. You may be able to get one via ebay at a reasonable price. However, I cannot guarantee the head is the cause of the problem, there are other potential electronic issues. Art

I've trashed 2 epsons by > attempting to clear a partly blocked head by squirting/blowing through it I used the compressed air on the 2nd try to revive it. The pressure was very low as the can was nearly empty , and it did clear a lot of ink buildup despite having cleaned with Windex |
