As soon as you take out ink cartridges, air will be introduced in the nozzles. This is the reason why the printer always do a cleaning cycle after removal/installation of print head AND/OR ink cartridge(s). Use the upload function on the menu bas of this forum. After upload, it will give you...

I think your purge system is not working. Since your print head works in your friend's printer. The purge system is used to suck ink out of the cartridges through the nozzles. If the purge system is not working, air may be trapped inside the nozzles to prevent ink going through the nozzles...

The rubber washer is not a solid piece of rubber. It will not work to double up. Here is another idea to try to increase the thickness of the rubber washer: You need to find a expired credit card or gift card plastic. Use the rubber washer as template. Cut a washer slightly larger than the...

Is the cyan ink level go down after a few cleaning cycles? If the cyan ink level does not go down and all other colors do, this means: 1. your purge system is working 2. the seal between the cyan cartridge and the rubber washer is not air tight. I had the same problem with the photo black...

websnail, I have problem figuring out your step #6. Please post picture if you can. Thanks.

Agree. It is the business model that all inkjet manufacturers used to make money by selling ink with cheap disposable printers. IMHO, it is cheaper to use laser printer if you do not print photos.

Let go with the spirit of this forum. I will refill the toner cartridge. It will not cost me as much if the problem is somewhere else.

I did that already and the problem remains.

Did you press RESUME once and then press POWER to execute the command?

My HP LaserJet 5L prints uneven darkness. Do I need a new toner cartridge? If not, what is the cause of this problem?

Search on eBay with the name of the parts. Few months ago, I purchased a fuser sleeve for HP Laserjet 6P. Google is your friend. You can find the how-to instructions using search engine.

I would flood the iP4500 purge pads with Windex after taking out the printhead. I am not sure what the printer will do without the printhead. If the Windex disappeared after close/open the cover, this means that the purge system is running even without the printhead. Flood the purge pads a...

I agree with ghwellsjr's recommendation of not taking the print head out for unclogging. This forum is open to all inkjet printer users with and without electronics background. It is dangerous to the health of the printhead if one does not know what is involved in drying electronics. The...

Don't give up. I know your feeling. I have been there before. Are you able to fix the purge unit? Is the water/Windex stay on the purge pads? The purge unit is used to suck ink out of the ink cartridge through the nozzles. It is the most important item second to the printhead. Without it...

Let me summarize the purge unit unclogging procedure. 1. Take out the purge pads. Clean the purge pad holder inlet port(s). Do the purge unit test again by flooding the pads with Windex or water. 2. May need to suck the clog out by using a syringe if clog persists. 3. Time to open the...

1. Always check and fix the purge unit first before doing any unclogging. 2. Check the rubber washer at the print head ink inlets for good seal. Air goes in the nozzles instead of ink if there is leak around the washer. Symptom: Ink level for the air leakage color will not go down after...

I added text labels on the photos.

Yes, the wrap is off the cartridge. I am here long enough not to print anything, other than nozzle check, if nozzles are blocked. I think the PH inlet screen is touching the the foam at the cartridge outlet port to keep the ink flowing into the yellow nozzles. I think the long term effect...

I measured the power usage after my Canon printer went to sleep, it uses only 2-3W. It will use 1Kwh electricity after 14 days. I pay 7 cents per KWh. I have three printers/AIO on my networks. The printer that I want to print on may not next to my desktop or laptop. It will be inconvenient...
