Printing on 5% = 480 pages (the official page yield). Printing on 10% = 240 pages. Printing on 20% = 120 pages. Printing on 40% = 60 pages.

Click the General tab, and then click Printing Preferences. Click the Basics tab, and then click About. Locate the page count at the bottom of the About This Driver screen.

Inkjet printers work via subtractive color mixing. As different colors of ink are combined, each ink absorbs (subtracts) its characteristic colors and amounts of light. The light that is then reflected back to our eyes is what we see as different colors.

Laser printers use microscopic ink particles in a powdered form known as toner. Once heated by the fuser unit, the toner melts allowing it to be fused to the paper fibres under pressure. Like inkjet cartridges, toner is most commonly used in the CMYK colours. Combined, these colours can recreate any colour palette.

Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.

Open the printer`s web page and Sign in as Administrator. On the General tab select Reset Factory Settings in the menu.

A new page should print with a claim code. If the page does not print, see the email address on the printer display. The first part of the HP ePrint address preceding “@hpeprint.com” is the claim code. For example, if your HP ePrint email is “abc@hpeprint.com”, then “abc” is your claim code.

Here`s a quick calculation you can do to get a rough idea of how many pages your cartridge will print. The manufacturer`s capacity is based on 5% of the page being covered in ink or toner, but if you are printing large shaded areas or more than 4 paragraphs of text, we generally print at more like 10 – 15% coverage.

Shelf life of printer ink in most cases is approximately two years. After that time there may be problems with the cartridge. The sponge designed to deliver ink to the printheads can dry out. The ink can begin to separate and turn to sludge.

A typical ink cartridge will yield 250 to 300 pages depending on the color density of the prints. The yield of a typical toner cartridge in a laser printer is between 2,500 and 3,000 pages. Some larger laser printers can even have toners that will yield up to 30,000 pages!

Fortunately, there`s a simple answer on how to count pages in a book for printing. To come up with the correct page count for your book or booklet, count every page, back and front, starting with the front cover.

Calculating Cost per Page

The math behind it is pretty simple, just divide the cartridge page yield by the cost of the printer cartridge. If we continue with our HP 64XL black ink cartridge example, we divide $41.99 by 600, giving us a cost per page of 6.9 cents.

A typical toner cartridge will produce anywhere between 2,500 and 4,000 pages, based on a coverage of 5% (roughly third of a page of double-spaced text). Dense pages filled with small font text or graphics will dramatically reduce this output and you may only get up to 1,000 pages per cartridge.

As explained, laser toner cartridges deliver significantly higher page yields than ink cartridges and last much longer. Where most ink cartridges will print between 135 – 1000 pages, laser toners can print anywhere up to 10,000 pages each refill or replacement.

Laser printers are built to accommodate the demands of a workplace so they are engineered to print faster (between 15 to 100 pages per minute, or ppm), while inkjet printers print slower at about 16 ppm.
