High yield - good choice for my Lexmark all-in-one

Good product, worth the few extra dollars for the high yield.  I was happy with the Amazon price.

I've been using this printer for 6 months.  I'm a software consultant and I need the ability to duplex print documentation.  For this primary task I needed a printer that could provide me with a quality document at a low, low cost.  Consumer Reports rated this printer very highly in those categories.  I would agree.  I print multi-color duplex documents with hundreds of pages and the print ink consumption is very low.  The quality is very good.  But don't confuse this printer with a laser.  It's an ink jet and provides very good print quality but not laser quality. It will operate at a very small fraction of the price of a laser though.  The interface is last generation with an LCD display but not a touch screen LCD.  You can get competitors with the touch screen and smartphone Bluetooth interfaces at about twice the price.  These were not my requirements and I saved that money for ink cartridges which are, in the end, most of the total cost of operating a printer.

The service was excellent from Amazon and Lexmark.  I had problems with print quality on the first two machines I received.  Amazon quickly replaced the first one since I was within the 30 day window.  When the second machine produced print quality issues I was outside the 30 day return/replace window with Amazon so I dealt with Lexmark.  They swapped out the second machine and the third one was the charm.  It was worth the effort but a hassle none the less.  One benefit of swapping out these printers was that I always received new print cartridges so I got about 120 days of free ink for my trouble.

All in all I rate this 4 stars.  Once I got a working model I was very pleased with the product and it's great to know that Lexmark will stand behind their warranty.

Update:  After using this printer for a couple of years I'm having to retire it.  Consumer Reports which initially rated it as a printer with low cost ink consumption changed it rating.  As CR has reported, if you just use the printer occasionally (30 pages/avg per month in their tests) it is one of the most inefficient and costly inkjet printer on the market.  They estimate that this model costs $122 annually to run the maintenance process if you are an occasional user.  I am an occasional user and have found this to be the case.  I have replaced this printer with an Epson WF-3620 that costs around $30 annually for maintenance ink.  Changed the rating to 3 stars.

It seems HP Printers are having a little trouble.  I had an HP OfficeJet Pro All-in-One printer, and it failed about a month ago (just when I needed it most and just outside of warranty).  I had lost a bit of confidence in HP Products, so I decided to look around for a different brand. I happened across the Lexmark Prevail Pro, and so far it works great.  I had a Lexmark Printer before, and it worked well while I had it.  This printer is easy to set up, and works fine with my Windows Vista.  I print student handouts for classes I teach, so the double-sided printing is exactly what I need to conserve paper. I also like the fact that I can scan documents to my computer via the wireless capabilities.  I probably will stick with Lexmark for a while.

An excellent all-in-one!

Unbelievably good print quality and speed. It prints EXTREMELY fast--you think it's in draft mode until you notice the print quality! Both text and graphics are very sharp and professional looking--I came from using a new $10k laser, so I'm familiar with top notch quality.

No problem setting it up with Windows 7 via USB.

Touch screen intuitive and easy to use.

I use the regular cartridges but they've lasted a good while, about 600 full cover pages for black and white on normal quality.

This cartridge has a pretty high capacity.  I've used it with my CX6400 printer/scanner/copier for the past 3 weeks and it's held through and I still have about 3/4 of the ink left and I've printed a lot of things.  Recommended from this site verses a place like Best Buy, who charge $12.99, whereas Amazon charges only $10.79.

Works great in our SOHO application as did its predecessor, a C543DN.  Toner is expensive, but buying the high-capacity cartridges from Amazon and using Lexmark's 10% recycle deal, it's manageable.  Factory support on old one was excellent and available (free) after the warranty had expired.  Hope they fixed the print head ribbon cable connector problem.  Odd thing: on the old one there was a cover over the rear printer tray opening.  On the new one the cover was not furnished or shown... but the old cover clipped into place perfectly on the new printer.

So far so good. I bought this a few months ago to be ready when my original toner went dry, which it did recently. It was easy and quick to install, and has provided no-problem, high-quality prints  at about half the price. So far it's 5-star performance, but I held back a star in case it doesn't keep up the good job as long as it should.

First time I'd used the 'high yield' print cartridge and was somewhat dubious about paying extra for an unknown 'extra' printing capacity. However, the enhanced yield proved to more than offset the extra cost over a standard yield cartridge. Too bad Lexmark designed these so they are not refillable, though.

I have an Epson Artisan 800. This printer, was a total "Ink Pig." Buying ink for these printers can be ridiculously expensive. After experiencing first hand all the ink consumption problems inherent with this and similar Epson printers, the purchase of a continuous ink supply system (CISS) made a lot of sense as the solution. After reading reviews of several of these continuous ink systems, I decided on this one. While this CIS is a bit more expensive than some of the others that are out there, I noticed that this particular system had gotten rave reviews from a photographer who seemed to know what he was talking about. He had also emphasized the importance of the ink quality that comes with these units. Epson inks, while expensive, are UV fade resistent and are high quality. If I was going to purchase a CIS, I wanted one that came with ink that was comparable. This system appears to be the answer. My Artisan 800 needed a few easy modifications to accomodate the installation of the CIS. The steps required are shown in detail on Youtube. So far, I'm very happy with the purchase.

I've had this all-in-one for less than a week so I'm still getting a feel for everything, but so far it's been great.  It's easy to set up and easy to use; something I really appreciate.  The software is fairly limited, but it does most of what the average consumer wants easily (e.g., red eye correction, resize, photo annotation).  For people who want a "very good" photo printer with the capability to do scanning and faxing in a small form factor and easy to use system, there really isn't anything that comes close.
Regarding the banding that a previous reviewer noted: I definitely see it if I use the cheaper photo paper (but it's not THAT bad IMHO), but I don't really see it at all when I use HP's "Premium Plus Photo Paper - glossy".  The paper is more expensive than the generic, but the generics generally only last 3 years whereas HP's (as well as Epson's) paper is expected to last more than 8 years.  If you watch the sales, I think the cost per photo is pretty reasonable.

Great product and value.  Crisp, clear, high-quality printing, copying and photo reproduction.  Better results than my old Lexmark.  Easy to set up and use.  Two "warnings:" 1) the printer does NOT come with a  cable, so order one if you need it; and, 2) the included software is NOT compatible with Windows-Vista, HOWEVER, HP will provide a CD with a Vista-compatible printer driver at no charge.  (You can contact HP via e-mail with this request.  They responded very promtly.)

As always, I was very pleased with the great service and prompt shipping from Amazon.com!

I've always found Lexmark ink to provide crisp, clear printing in both black and white and color.  Buying the bundle pack saves money as opposed to buying both cartridges individually.

The nice thing about buying ink from the manufacturer is you know it will work and give good quality printing.  This is certainly the case with this ink from Lexmark.  The cartridge slips perfectly into place and is immediately printing deep black print.  No issues with the quality on this unit.  I just have the usual rant about a product that costs 50 cents to make is being sold for $15.

Pros:
o high quality ink
o 100% compatible
o relatively inexpensive (in the larger context of how much one might pay for ink for other printers)

Cons:
o I would still like to see ink at about 1/2 the price... I know, I'm dreaming...

Overall - if you have a Lexmark printer, this is excellent ink.

Really happy with this printer - it replaces an all-in-one older Lexmark that had had one problem after another.
I was in a hurry to get this one set up - called Canon's customer service #.  Wow!  English-speaking, patient and thorough - it was an unexpected joy to deal with them.  Got the printer up, running, connected to wireless easily and quite quickly.  So far am more than pleased with the printer.  A good choice at a very reasonable price.

I have had this for more than 1 year without any trouble.  The features work as described.  It goes through ink faster than I would like, but don't they all?  Then again it was a replacement for a Lexmark, so anything would look great by comparison.
