How can I reset the ink in a canon mx870?

SOURCE: Prints without any errors but no ink on the paper.

if you have new print head assembly and cartridges, and waited for flow, and the printer is MECHANICALLY sound (not dropped or G-force damaged), then all that is left is improper cartridge installation. You may not have the cartridges fully inserted/, or maybe they are not PROPERLY inserted. Look for a snap when in place (and no wiggle). I suspect this is your problem, because one symptom you mention, ink accumulation INSIDE the head/cartridge cradle, is VERY rare -unless the cartridge is inserted improperly. The cartridges/head assemblies have VERY good seals to prevent leakage. Unless the o-rings/seals are damaged, leakage outside the seal just does not happen at all, normally.

*New head/cartridge installs can take several hours -sometimes even a day in cold weather, for small iP90-like printers to saturate the heads -and print.

I've heard that with canon there is a way around the ink-level chip monitoring on the cartridge by doing the following:

1. Power off printer
2. Hold RESUME button then press and hold POWER, the beeper will sound once.
3. Hold POWER and release RESUME
4. Press RESUME twice
5. Release POWER button
6. When the indicator lights steady, press RESUME three(3) times. The indicator should be orange.
7. Press POWER to set data

I had same problem today. Removed print head and bathed it in alcohol for half an hour. Then I removed the two screws underneath and used a syringe to squirt alcohol into the ports and clean. I noticed clumps of ink coming out (i guess some ports were blocked). I then dried the head and reinserted and reinstalled ink tanks. All looks good so far- black printing again and printed test patterns all look correct. Good luck.

ALL…. Epson & Brother Requires Genuine Epson Cartridges. !!!!!!!!
That sounds like your problem.

In Purchasing Epson's CX 5400, CX4600, & CX7400 and more, I found out that Epson does not like Generic Printer Cartridges. I also Purchased a Brother. That also does not like Generic Print Cartridges. Color that should be Yellow, will turn out Green, Blue Brown, etc.

These printers have a CHIP that will detect if it is Generic or Genuine. When they see it’s Generic Cartridges, it will print lines thru the words, stripes across the picture and also do a mix match with the colors. It also will not let you print anything, if only one of the cartridges is empty.

I wanted to print only Black, and would not let me, because I did not have any ink in one of my cyan cartridges. Go figure.

That's what these Companies do., so they can keep selling the ink cartridges. Some Printers, are able to use Generic, and some are refillable. Some you can refill them up yourself and I heard, quite MESSY.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for these PRINTERS. Some people say some models work fine compatible, but not mine.......

I had to replace the printer, but Epson, Lexmark & Brothers are always on sale. My Brother & Epson cost me $50.00 with Rebate. .

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)
