Canon MP 610 printer. Cartridges half full when forced to replace

Copy machine makers are notorius for forcing users to use a bit of the more expensive color mixed in with black. I can't print in black, it is called greyscale, therefore it has color in it. If you only print in greyscale, you'll notice your color cartridges going lower over time.

Try taking the cartridges out one by one & clean the contacts on each one with a little warm water on a small piece of cotton,check that none are leaking, bulging or have any tape over air holes. Then replace. I did this and it worked OK.

Maybe it's time to replace the PRINT HEAD

That sounds like the ink is coming off the waste ink absorbers. Try blotting the excess ink off the bottom of the printer with paper towels. The ink absorbers are small pads at the bottom of the paper feed path. With work, you can pull them pads and rinse them clean and then reinstall them when dry. Unfortunately, this can take almost disassembling the printer. Simply absorbing some of the excess is a temporary step.

I hope this helps.

(there is a counter that indicates when (based on average use) the waste ink absorber is full. The printer will stop working when that number is reached. Unfortunately, I haven't seen a reset for this model that actually works.)

You probably have bad cartridges.
Email Canon and see if they won't send you replacements.

Replace the pickup rollers and check the Gears if they become bad.

Have you replaced that Ink cartridge with a new one? If the problem is the same it might be a problem with the print heads (cartridges holder).

What setting on the MP610 do I use to print on transparency sheets

Here is the link for your manual. Just scroll down to section with guides and pick the one for your operating system ( just in case you need it for something else at a later time )
