Hello. I need help with a Canon Pixma iP4950 inkjet printer. The printer was used mainly for printing photos, so there is not much overprinted, max several dozen sheets. Recently, I was printing about six months ago. Today, after turning on the printer, the orange LED flashes 5 times. When selecting "Printer and Ink Status Information" from the Control Panel> Windows> Devices and Printers> Canon iP4900 Series, it displays information as in the attached screenshot ("Canon error.jpg"). The manual attached to the printer says nothing about 5 flashes of the LED (attachment "Canon manual.jpg"). According to information found on the Internet, the orange LED flashing 5 times means a problem with the head. Most of the advice is "wash the head under water". I have done it many times, because it's the 3rd Canon printer in the family, so I did it now and unfortunately it didn't help. I put on a new set of carcass (I have a few spare sets) with new chips - nothing. I reset the ink level using the button combination at startup - holding the Resume button turned on the printer, released Resume, then pressed it 2 times, the orange LED flashed, released both buttons - nothing. I downloaded the program "Service tool v3400" from this site: https://grandcousin.com/canon-pixma-ip4950-reset.html and I wanted to follow the instructions there, but it probably won't help, because it's about resetting the carcass level, and it seems to me that since I have chips in every set, I don't have to do it.
Please advice if I can deal with it somehow. The printer is almost like new.
I probably made the mistake of running it without ink and with a clogged head. I thought that if it had been standing and moving for 2 years earlier, now, after another six months, it will also start, and if there is no color, I will open the head and replace the carcasses. And she probably burned out. It pays off to buy a new head? I found the cheapest for around PLN 280. Apparently this printer is very good, they use it in photo shops. If I had a new one, I would print more often and clean this topic more often: https://www.elektroda.pl/rtvforum/viewtopic.php?p=13157452#13157452
I also found out that there are cleaning cartridges, maybe I would start using it and the new head would last longer?
Cleaning cartridges can get stuck. Some cleaning fluids cause some type of corrosion in the nozzles and this is manifested by reduced nozzle capacity.
To unblock the existing heads, I use steam from the kettle directed at the plate with nozzles (max 1 minute) and then dry with a dryer for a few minutes. Interestingly, under the influence of heat from the dryer, the old ink flows from the inside of the head - apparently thermal inks become thinner at higher temperatures.
Hello. What happened to the WSI Servant user? He offered to help me repair the head so that I could send it to him, and when I did, he stopped responding to messages, and now when I wanted to write another one to him, I can see that it has been removed. Can someone explain it to me?
