Printouts have horizontal banding

I have a Canon MG 2220 printer.

I have having problems with my printouts having horizontal bands across them.

I have cleaned heads using CUPS.

I also just physically cleaned the printer heads.

There was a lot of ink and some was pooled on the bottom of printer.

I refill my cartridges.

Picture of printout is here.

Why not just try new or rebuilt cartridges?

I wonder how they drive that ? 7680 holes, 9600 DPI ?

https://i.ebayimg.com/images/g/t-gAA...ocm/s-l300.jpg

What kind of electrical interface makes that possible ?

It's amazing. It looks like the color and the black cartridge
have different heights on their print surface.

https://www.amazon.com/Novajet-Reman.../dp/B072KDM2TW

Are those the right cartridges ?

Something has to drive out a pattern at high speed (serially)
to the Kapton film top contact, and from there, to the
micromachined head. There must be a chip in the head that
decodes and stores the high speed pattern, to print out a
column of dots.

I think I'd inspect the platen (the running surface the paper
rides over) for roughness.

The only way a thing like that could foul up, is if the
connection memory inside the printer is defective. Like, if
the original cartridge and the replacement cart print
*exactly* the same defective pattern, maybe it's an
electrical failure of the board/chip inside the printer.
I can't imagine a processor driving out the pattern
directly, and maybe something loads a whole row into a
RAM, before the printer starts a run across the sheet
or something.

As an example of the concept, we had a printer at work with
a "video interface". The signal concept was similar to
a TV set, and pixels came belching out at 2Mbit/sec.
And the printer scanned that pattern across the surface
(it was a laser). So that was high speed serial too. And
if you wanted gradients, they were done with halftone
(in software).

Oh, I missed reading amongst all the threads.
That puts a completely different light on the subject.

They are the right cartridges.

It's amazing what they can do.

I have already invested a lot of time into the problem.

My b/w laser is good enuf.

If I really need a color print, I will take a flash drive to Office Depot.

Andy

I predict that when the scanner goes out, I will take the printer totally apart.

Then I will find and be able to fix the printer banding problem. :-)

Murphy's strikes again.

Speaking of it's resolution.

It's so good, that I can see things that I would need a magnifying glass to see on the item scanned.

The scanner is like a microscope.

Has anyone had an inkjet that lasted more than 5 yrs without need a repair.

And that is refillable?

I am looking at Epson Expression ET-2750.

I read where dust on paper is bad on printer heads.

Good, not great

Unlike all but two reviewers who received this printer for free,
I purchased it. SO my review is not paid for. Any reviewer who accepts
a free item is not unbaised.

This printer is a pain in the tush to set up .

It does not use a USB cord for connections so the set up time is
lengthy. If this is not done exactly as explained you're SOL..

Printing quality is fair. Speed a bit on the slow side. The cost of
the ink is really the biggest draw. But t his also depends on how
much coverage your printed pages use. I have not been through an
entire cartridge so I cannot comment on the veracity of the page
claims made by the manufacturer. Overall if you want a basic printer
and are willing to spend a lot more for the printer up front in hopes
of saving on the ink , this may be for you.

Other printers exist which are better but the ink is more expensive.
If you print a lot the cheapest path is still laser color printer.

Your right about color laser printers.

But refilling them is still rather expensive.
