Summary: THE PRINTER SAYS THEY ARE EMPTY BUT I STILL GET ANOTHTER 300 TO 500 PAGES WITH COLOR CARTRIDGES & IF YOU TAKE THEN OUT & SHKE THEM I GET EVEN MORE. RIGHT NOW I HAVE 3 COLOR CARTRIDGES THAT TOLD ME TO CHANGE THEM JAN 5 2014 IT IS ALMOST MAY & I STILL HAVE THE SAME COLOR CARTRIDGES, SOME TIMES A PROTION OF THE PAGE GETS LIGHTER , THEN YOU TAKE THE CARTRIDGE OUT & SHAKE IT SIDE TO SIDE & REDIDTRIBUTE THE TONE INSIDE & I GET ANOTHER 50 GOOD COPIES BEFORE I DO IT AGAIN.
Excerpt: Toner is so much better than ink. First of all, it doesn't dry out. We don't print a lot in color, but using toner has made printing in color more reasonable. These cartridges last us quite awhile!
Pros: Long Cartridge Life, easy to replace, Clean Replacement
Summary: We purchased the HP Laserjet 400 color M451dn, before that we went through countless All-in-1 printers and this is night and day difference. As a dedicated Printer for our office, this printer is fast and efficient. The yield for black 305A cartridge is 2200 pages we always get at least 3000 pages(lasts about 1.5 months for our office.) before changing it out.
Summary: Had to replace 305A black cartridge after only 1256 pages printed when should get around 2200 pages. In other words, I only got 57% of the printed pages I should have received before needing to replace the cartridge. I'm on the second black cartridge now. It has printed 264 pages and shows 700 more remain. So again looks like will only get around 1000 pages. Like the HP LaserJet 300 color MFP but print cartridges need to be replaced too often and are expensive.
