printing at Altitude

[Kerry1209]

Should inkjet cartridges last as long at high altitudes like 10,000ft?  We just bought this printer and the cartridge only lasted about 50 pages.... spec say it shoudl give me 200 pages of printing.

And what are you printing?  Text, color, graphics, photos?  How much ink on each page?  Need details...

Just text in black and not even full pages of text...thanks for responding!  We are new to 10K feet so were thinking the low air pressure might be affecting the cartridge

Here is a chart to help with Ink Cartridge Page Estimation.  All cartridges are based on a 5% coverage when new.

Note:  A 5% coverage is about 6 single spaced lines of text on a page. No bold, graphics or pictures.  A full color photo would be 100% coverage.

A ‘regular’ page of text would be about 72 lines and give us 30% coverage (more realistic).  Don’t forget the font type and size you use will use more ink too.

Example: 564 Standard Black = 250 pages at 5% coverage.  

Let’s say your average page coverage you estimate is 30%.  So…250/6 = 41.

Therefore the number of pages expected (30% coverage) out of your cartridge would be about 40 pages.

A 564 Standard Color (300 pages) at 100% coverage yields – 300/20 = 15 pages.

***********************

Your printer uses HP 64 starter cartridges rated at 185 pages for black and 120 pages for color, at 5% coverage.

I estimate your coverage at 30%.

So here is your math.

185/6 = 30 pages for black, 120/6 = 20 pages color.

If we estimate a 20% coverage, 185/4 =  46 pages black, 120/4 = 30 color.

You are right on target and may be doing better than expected.
