Very difficult to use.  Does not hold ink well right out of printer.  Shot it with 3 coats of clear before trying to mount on slick surface ... epic disaster!

DO NOT BUY.  An utter disaster.  Oh, it prints alright... when it has ink.

I bought for occasional business use a couple of months ago. I have yet to run through my first ream of printer paper with it; my usage is very, very light.  And yet I have already been to the store MULTIPLE times to buy ink cartidges, including an "extra large" black ... went to print a 7-page document this morning, plain text only filling a small portion of the page... and it's out. AGAIN. Go to store yet again?  No.  No. I am at the point of resistance, the point of rebellion.... I plan to throw this piece of trash away and try something else.  It does not meet minimal expectations for the capacity of the cartridges.

Do not believe the company's claims regarding lower cost of ink.  The cartidges on my old HP were expensive to replace, but lasted a reasonable time when you did.  This is just as expensive and dramatically less convenient.

Printer is ok, but it uses ink like crazy!! Don't let it stand a while, it will make you replace the ink.

It is nearly impossible to get a decent color print out of this.  In addition, it frequently will not print one or more colors at all, or will print with streaks, until one does the (time- and ink-consuming) cleaning and alignment of print heads.  Finally, it prints text with the lines of ink misaligned - resulting it regular type looking like italics.

First try on most prints usually results in a washed-out (unsaturated) print, often with a cyan cast.  It takes several tries (time-, paper- and ink-consuming) to get a decent print.

Nice to have an large copier and scanner, hence a second star.  Printing gets only one.

Doesn't write consistently. When it does, the ink if an odd color & irregular. Don't purchase.

They were hard to get ink to come to the tip of the marker. They were more wet than I imagined and were really messy! Took forever to dry. They also don't erase very well if you need to erase a mistake like you know you might with regular chalk....

Very hard to put the ink in the cartridges without getting ink on your hands.  I do admit this was my first time trying this.  However next time I will buy ink in different containers.

This product is more trouble to use than it is worth. I would rather rate this product with no stars.

Not a big fan of these. They take FOREVER to dry. It truly takes 4-5 minutes for the writing to dry. If you touch it at all before that, it becomes a giant, smeary mess. Tricky for me to use, really frustrating for my 9 yr old I bought them for.

I have previously had Epson printers and really liked them. I am very disappointed with this one however. I bought this partially because it appeared to have an easy-to-use and solid command board, which I highly value. I have just spent the last 15 minutes (that I didn't have to spare) simply trying to change an ink cartridge because the printer does not respond to the commands Epson online tutorials claims it should... the ink cartridges remain stubbornly locked behind a plate, disallowing access. I have had a ton of trouble with this thing, as has everyone in the office that has tried to use it for copying or printing. It seems to respond how and when it feels like it and I am very much regretting buying it.

****update.... I loathe this printer, and unfortunately bought two for home and office so feel stuck with it. When I want to make a simple copy or print a simple piece of paper, you must answer 20 questions, often does not reapond, the manual is of little help, and it is extremely slow to respond. What shiuld and always has been a simple process (with other printers) is overly complicated and non-intuitive. Oh how I wish my old Epson could have hung on for a few more years!!

Not a good printer. Ink very expensive, color not good quality, printing speed slow. Installed and reinstalled, cannot scan with it. Does not work with a network, and does not support MAC. Of course we cannot return it. Asked to return it the third week we had it and it was not possible. $400 down the drain.

way to slow to print, ink runs out super fast and cartridges are ridiculously expensive. Mostly, the biggest complaint is that sometimes it takes several minutes to an hour before it will even print the doc that i have requested. Have reloaded software multiple times and doesn't help.  The photo quality is nice, but really not worth the hassle.  Would run this over with my car, but i prefer to recycle.  Very frustrating machine if you like things to work fast.

I was originally very pleased with the WF-3620. Which is why Im reluctant to even give it 2 stars

This printer guzzles ink like no other. If you are working on a black and white project and you happen to have run out of the other colors the day before, you are plum out of luck. You won't even be able to finish a regular word document.

I called Epson and the tech help told me that I must have ink in ALL the cartridges in order to print in BLACK! this makes no sense to me! I asked the tech help why it needs the other cartridges to have ink in them besides black. He responded with. The printer uses all of the cartridges when printing in black.

It seems like this is a way to sell ink. In no way does this feature assist the users of this printer. There is no way to over ride this feature either.

POS! Not a business machine. Incredibly slow.  Even though you keep the ink full after a couple of months the print is faded.  DO NOT BUY THIS FOR YOUR BUSINESS! THE AGGRAVATION IS NOT WORTH CHEAP INK. I've had it for 3 months and for New Years Eve it will be hosting the biggest fire crackers I can find.

Definitely don't recommend it. The printer jams so often and the printer's design does not make it easy to clear a jam.

Don't bother. This pen is terrible. I can't believe Uniball put it's name to it. The ink is inconsistant.

Slow. It has to worm up for couple of minutes before each printing sessions. After the worm up it can print about 5-8 ppm for documents in black, which is much slower than what was advertised. One of the reasons for being slow is that this printer flips every sheet of paper, even when printing one side, which is very frustrating. Right when I think I can grab the paper, the printer sucks it right back in to flip! WHY!?
An ink gobbler! For every 5-10 color photo printing, it spits out the sheet half way done and tries again with a new sheet, wasting my photo papers and ink! It also uses ridiculous amount of ink to clean nozzles.
After 4 years of frustrating experiences, it died... B200 error code. Apparently Canon is very specific and breaks easily with cheap 3rd party ink.
I am staying away from Canon printers until the cost of ink comes down or it can work with 3rd party ink.
