It does sound clogged. To try to get it unclogged, try:
1. Fold about 2 feet of bathroom tissue together 3 times into a square about 21/2 inches wide, and place in disposable container (like stryo cup). S lo w l y poor hot boiling water over tissue till saturated, and place cartridge on in it until it covers the bottom of the cartridge. Press down as needed to make sure bottom is in the water. Leave for about 10 minutes.
Gently pat cart dry with tissue, and place in printer and test. It is best o make a fully black test page. (If you have a Word pro, go to Format?Background and choose black.
2. If that does not fix it, go to Start>Settings>Printers, and right click on the printer you are using, and choose properties, and look for the option to clean cartridges.
1. When cartridges are used up, seal the bottom with tape and place in airtight bag until ready to refill.
2. To save more money, (pray and) price bulk ink and use that and a syringe (you can buy basting syringes at some kitchen good sections in stores) to refill. You will need to heat up a paper clip till red hot and melt a hole in the front the cartridge.
Note: modern carts can only be filled in one half, as that is how they make their money after selling low cost printers.
Been refilling my old Z-32 for years, using bulk ink (about 1.50 per refill), praise the Lord
