I would try using a set of OEM cartridges. Make sure to run deep nozzle cleaning and alignment.
Some aftermarket cartridges are not as well quality controlled and tend to be inconsistent and gum up the nozzles.
If you need a source for good aftermarket cartridges try LD Products online.

Canon mx860 printer not using ink from PGBK 220


Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

How do I reset or disable the ink level indicator on the Canon mg2120?


Inkjet cartridges dried up at the nozzles. Can be dissolved by water to print again. Refill cartridges done by yourself can have dried up ink left in the cartridge to make it too concentrated. Too easy to dry up.

Epson Stylus 440, solid light on for black ink, have replaced and still won't print


This morning I was researching to purchase a new printer to replace the 10 year one. The last cartridges I had purchased were from Printpal and made in China. They looked the same, but I had to force the door closed on them. With the solid red light on and replacing the cartridge three times with new ones from this order, it was time to find an old used cartridge from another company that I intended to refill myself. I did, installed it and the solid red light disappeared. The old Epson Stylus 440 is still ticking! However, I had written off InkGrabber for unused cartridges going dry in 2 months and now Printpal is on my $%%# list for non-uniform replacement cartridges as well as not lasting long. I am back to refilling my own. I had followed the instructions for resetting the ink level indicator, but to no avail as those instructions are for a blinking light, not a solid light.

I appreciate your website, if for nothing else, to be able to vent. Thanks so much for your follow-up inquiry and I'm sure you'll hear from me again soon about my old Epson.

Printer cartridge problem


I have a 440 and have had the same problem. Of course, I have been using cartridges from Printpal, Inkgrabber, etc. that are not official Epson. I have found that it takes several cleanings and after the cartridge has been in the position for the ink to go down it will start. My last order from Printpal said to set all the cartridges in the position they are in when installed in the printer for several days prior to installation. Of course, every cleaning of the print head uses up more of your ink. You don't have much choice though.

Black ink not printing


Fix ink cartridge
I had same problem. I must have ran the clean cycle more than 30-50 times over a period of days. That never made any difference. I was about to toss the whole thing but figured I would try one more thing. If it didn't work I would be in no worse shape. Here is what I did.
Took an almost empty black cartridge and inject a lot of 100% Acetone to dilute ink. Left some black in it since I didn't want to think it was empty. Inserted this cartridge and ran the cleaning a few time. IT WORKED. I used my word processor program and filled a page with large bold font characters and printed a page or two. Each page cleared more nozzles. After doing this cleaning/printing a number of time, I put in the full good cartridge. Ran the cleaning a few time to eject any of the Acetone diluted ink. Ran the printed page a few time to remove more of the diluted ink.
Everything seems to work now.

Thanks for getting back to me.
Sorry this ain't a solution but it seems to be the only cash-free way to contact you. No problem not solved - though I have tried everything. Dismantled the printer; washed, dried and replaced the waste ink pads; washed the print head; blew compressed air through the print-head sponge; replaced the cartridge 3 times; printed hundreds of test prints. I can't think of anything else to do and so I think the only solution is to replace the printhead (probably not even available) or replace the printer. The latter is looking most likely.
