Inkjet pages per cartridge

by joe97603 - 7/13/07 10:03 PM In reply to: In response by rhomp2002

5000 pages for an inkjet cartridge? What kind of printer are you talking about? Typically, I see 200 - 300 pages per cartridge. I see HP states 450 pages and Epson 300 pages for their products. I use a laser because the inkjets kept drying up before they were empty

Sorry, I misstated - here are the figures for my printer

by rhomp2002 - 7/13/07 10:29 PM In reply to: Inkjet pages per cartridge by joe97603

HP 88 Large Black Ink Cartridge 2580 standard pages
HP 88 Large Magenta Ink Cartridge 2190 standard pages
HP 88 Large Cyan Ink Cartridge 1840 standard pages
HP 88 Large Yellow Ink Cartridge 1650 standard pages

That is for an HP OfficeJet Pro K550


Black cartridges are $34.99 and the others are $24.99 from HP online and can be bought for about half that in OEM.

HP 1600 Color Laser Jet is:

Cartridge Average yield1 Page Example

HP Color LaserJet Q6000A Black Print Cartridge 2500 standard pages
HP Color LaserJet Q6001A Cyan Print Cartridge 2000 standard pages
HP Color LaserJet Q6002A Yellow Print Cartridge 2000 standard pages
HP Color LaserJet Q6003A Magenta Print Cartridge 2000 standard pages


Black laserjet is 74.99 and the colors are 82.99. Big difference in pricing for about the same yield.

Again these are the prices from HP online store. You may be able to do better with an OEM product.

Right now I am using OEM cartridges that cost me a total of $65 for the 4 inkjet cartridges and they are working out well. I am on the 3rd ream of paper and no lessening of quality. I am using regular print, not draft, or I would get more pages still.

Now do that on a monochrome laser.

by R. Proffitt Moderator - 7/14/07 6:08 AM In reply to: Sorry, I misstated - here are the figures for my printer by rhomp2002

Also use the refill cart since you did that on the inkjet.

These analysis have been done to death, the monochrome laser won.

Monochrome laser? why

by rhomp2002 - 7/14/07 9:34 AM In reply to: Now do that on a monochrome laser. by R. Proffitt Moderator

Part of the reason for printing is the colors. I am comparing like with like. I am also reporting the cost both as HP hsa it and as I have found with my OEM refills.

If I have a printer that does colors, then I should be comparing it with the laser that also does colors, else why would I be using colors in the first place. Then add the cost of the toner up and you have $300+. Add the inkjets from HP and you have $110. The number of pages per each is approximately the same.

If I stick to a monochrome laser, then of course the limited capability would allow the laser to win. However, if I use the capability of the printer to do colors, then there is absolutely no comparison that the inkjet is far less expensive - and that is comparing the costs at the HP store itself - not refills.

Printing Black Only With Epson CX6400 Stylus

by Leroi82 - 7/14/07 12:27 PM In reply to: Now do that on a monochrome laser. by R. Proffitt Moderator

When the Stylus comes from the factory, it is set to
mix the four ink font together to make black. It is not only expensive but not a very black black color.
There is an easy solution. Go to Control Panel; open Printers and Faxes; Rt click on printer (Stylus CX 6400); on dropdown click on printing preferences; click advanced,click on continue; on left side, place check mark in "Black Ink Only"; click OK.
Printer automatically prints all colors when it is specified on a particular item and then defaults to black onlyfor all other printing. Uncheck the item if you ever decide you don't want to use the black onlt option. I have cut down my purchasing by 60-70 percent. Good luck

Still doesn't solve the issue(s).

by R. Proffitt Moderator - 7/14/07 12:32 PM In reply to: Printing Black Only With Epson CX6400 Stylus by Leroi82

1. It still eats a little color as it starts up.

2. It still won't work when the color carts are empty and you have plenty of black.

I understand what the OP wanted but I haven't found a inkjet that does this. As such the nod is to get the right printer or cheat and fill them all with black.

My statement is...

by R. Proffitt Moderator - 7/14/07 6:06 AM In reply to: In response by rhomp2002

I decline the analysis because it's been done. You can do the research and draw the conclusion again.

Here I will share my experiences and results and will decline duplication of effort.

Hope you understand,

Bob

Good and Bad advice.

by albizzia - 7/26/07 11:57 AM In reply to: Cheat? by R. Proffitt Moderator

Yes, "leaving it on" is one way to save ink, though it does waste a little power. You see, this particular model does a "nozzle cleaning" routine each time it is turned on, and that does use some ink. You might think of this as a "workaround" until you can get a different printer.

There are printers that do not do this - most HP models (I have a HP 952C, no "wasted ink" problems) and if I'm not mistaken, most Canon models as well. My HP printer will tell me when it thinks an ink cartridge is empty (it often gets it wrong, says it is empty when there is plenty left) but will print anyway.
The new Canon models have a very good ink level sensor and separate cartridges for each color, but I suspect it might not print if a color is out - check with a Canon expert on that one.

But "filling all the cartridges in black" is a very bad idea. Not only will that interfere with color printing, it might even void the warranty! The Epson has the non-removable printhead separate from the ink cartriges, having black ink where the color inks should be will mean it would be a long time (and a lot of color ink wasted) before it could ever print color correctly again. In some cases it could also interfere with the color registration process, causing the printer to stop working.

You might check in the "Print Options" when going to print, to see if there is an option for "black and white only" printing. That might be a possible workaround for printing with an empty color cartridge.

Coincidentally, my HP printer is usually left off. It will automatically turn itself on when I want to print, via the USB connection!

inkjet printers efficient use of ink

by Smittys2 - 7/13/07 7:23 PM In reply to: inkjet printers efficient use of ink by glenn623

I DON'T KNOW IF THE FOLLOWING WILL WORK ON AN EPSON BUT IT'S WORTH A TRY.
IN THE COLOR SELECTION FILE SELECT "PRINT IN BLACK ONLY" OR "GRAY"..

OCCASIONALLY I RUN OUT OF COLOR AND EVERYTHING GOES SOUTH BUT WHEN DOING AS I SUGGESTED ABOVE I HAVE BEEN ABLE TO GET DECENT RESULTS WITH BLACK/GRAY ONLY, IF NEEDING TO PRINT TEXT ONLY..
GOOD LUCK

Try "Not Printing"

by retexan599 - 7/14/07 6:47 AM In reply to: inkjet printers efficient use of ink by glenn623

What I mean is that I am trying to get away from printing, per se. For example, I bought a digital picture frame as the medium for showing my digital camera photos. Why print the photo unless you really have to? Sometimes you do, of course, but a lot of the time you don't need to have a printed photo. Similarly, for text, I try to use email. Also, when possible, I transport files on a memory card that fits in my wallet if I want. Sometimes I think that the more computers we have, the more paper and ink we use!

Try a Kodak 5300

by frustrated bigtime - 7/14/07 8:09 AM In reply to: inkjet printers efficient use of ink by glenn623

I did endless research when my HP1000 wouldn't work with any of the new computers (HP won't provide a driver for it, and it just happens to keep printing forever in black even if the color is dried up, and has a huge #45 black cartridge holding 42 ml for $30 that lasted me 6 months) and the Kodak wins hands down in the pages per dollar of ink used. I tried HP4240, it only made it to 125 pages in black draft before it ran out, their statistics say 170 pages for one cartridge of black, the 4.5 ml size for $17 at Office Depot. The Kodak has already printed a couple hundred pages of text (using draft) and it hardly made a dent in the black ink. I had trouble the first time I tried to print photos from a card, because I didn't know how to remove the printhead and reinstall when I would get an error message that it was misaligned or missing. Once I got the reply from Kodak and did it, it worked like a dream and no glitches since. After the 4240 fiasco I bought a HP 5180 (before I knew the Kodak existed) because it at least had a 16ml black cartridge showing on the box. Alas when I got home and started checking on the price of replacements, they only make a 10 ml to fit it. The 16 ml that comes with it is to keep you going past the time you have to return it to the store. So I returned it without even cutting the tape on the box. :o))

Go to Kodak website and look for their usage chart - I think they are being conservative. And even better - they use pigment ink instead of dyes. You know how water or dampness on an inkjet page melts the ink and it runs off in puddles of color? Kodak ink is water resistant and doesn't melt. I just stuck a page under the water faucet and wet it good, I can tell when it's completely dry the ink will still be in place. Your photos won't start fading in the sun either.

Epson vs HP

by goddessofmusic - 7/14/07 9:19 AM In reply to: inkjet printers efficient use of ink by glenn623

My HP Photosmart C5180 has six color cartridges, costing around $10 each. The advantage is that if any one of the cartridges runs out -- as long as they are in place the black will print on its own. Each can be replaced separately,and a message tells which one is out, unlike the tri-color cartridges of other printers. The color is also richer.

Get a Lazer

by marpincan - 7/14/07 10:50 AM In reply to: inkjet printers efficient use of ink by glenn623

I had an epson and an hp injet. I bought a color lazer and a mono lazer and tossed both inkjets in the garbage. The mono is a konica minolta page pro 1350w and the colour is a konica minolta 2500 w. These are both bottom end printers but produce excellent results. With the mono printer, i can order a toner refill kit (6000 pages)for around $20.00 plus shipping on ebay. The color printer refill kits are more expensive and you need 4 (black plus the 3 basic colors). Cost for all 4 refill kits is about $120 on ebay. (good for around 3000 sheets). The cost difference for the refills is why I have the 2 printers. Also note that the drums are only good for 16,000 to 20,000 prints (for most home use the printer should be obsolete by the time you reach this number). I have had these printers going on 2 years now and refilled the mono one once. - no problems and easy - also note that the cartriges that come with the printer are only filled to give 1000 or so prints - then you have to replace or refill. I find refill easier than for an ink jet and you should be able to refill a cartridge about 3 times before you need to replace it. Then the choice is to replace it or buy a new printer (depending on cost).
What ever brand of printer you may decide to buy if operating costs are important to you, my advice would be to first check the cost of supplies on ebay.

A point or two not discussed previously...

by grtgrfx - 7/14/07 9:19 PM In reply to: inkjet printers efficient use of ink by glenn623

First, you should consider a BW laser printer and a color inkjet if you don't mind gray output for some print jobs. But even if you chose a color laser cartridge like Konica-Minolta or HP, their cartridges have capacities far greater than those in an inkjet.

Second, I don't think any inkjet cartridge prints more than 300 pages and many (especially the photo-realistic printers) hold ink for considerably less. Cartridges are (conservatively) rated for printing with 5% coverage per page. That means if you're producing a mostly-text document with a few charts, it'll use far less ink than if you print a full-page image of a photo you took. So right there the printer companies are misleading you with a rating based on minimal usage for business documents. If you print photos your usage may drop to under 100 pages per cartridge.

The idea that an ink cartridge for an inkjet can print much more than 1/10th of a laser cartridge's capacity is just wrong. So there alone, the cost of 4-6 low-capacity color cartridges may be more than one black laser cartridge and print far less.

Finally, laser printers do not "prime" their print heads on startup or use any ink during cartridge replacement. They only output toner when an image is put on paper. Right there you save 1-2% on your ink usage.

Looking at all these factors, the most important question you need to ask is not "how expensive is the ink," because that will be obvious -- laser ink is cheaper all around. The real important question is "which printer produces the most attractive reproduction of my color image...inkjet or laser?" Usually inkjets just look more natural and less streaky for printing color images, and that's why they are popular. Their drawback is that consumables are pricier and need replacement more often. Lasers are more economical and need less fussing, since there are no print heads to clog, but output still isn't as good even after all these years. Save money...buy a laser to supplement your inkjet. Leave 'em both off to save energy. Print black only to save cartridges.

You are so wrong about the number of pages inkjets print

by rhomp2002 - 7/14/07 10:14 PM In reply to: A point or two not discussed previously... by grtgrfx

If you look above, I copied the page capacity of the larger inkjet cartridges of my own printer from the HP website. The page capacities are over 2000 pages per cartridge. The black is over 2500 pages per cartridge.

I know myself that I get at least 4 reams of pages before I need to change the cartridges and get good print results as well.

I also have used refilled and OEM cartridges with no problems as well.

I think you need to revisit your comments and check with the latest printers as they have changed drastically. Maybe in the older printers the cartridges were only good for 300 pages but the newer ones are good for far more.
