My Lexmark laser printer started complaining about low toner in the back cartridge today. I’ve had the printer just over a year, but even so, I was surprised that it had got through 2500 sides of text (what the black cartridge is rated at) so quickly.
So I checked the statistics. The 543DN has an inbuilt web server that provides all kinds of helpful information, including the fact that my cartridges are:
- Black: low
- Yellow: 80%
- Magenta: 30%
- Cyan: 50%
There is lots of information on the pages printed, including average job length, job type, etc. It turns out that I’ve printed a total of 519 jobs, of which 474 are 1 or 2 pages long. My longest job was 23 pages.
I’ve printed a total of 312 mono A4 sides, and 499 colour A4 sides, for a grand total of 811 sides overall.
And because my “2500 sheet high capacity black toner cartridge” is nearly empty after only 811 sides printed, this is where I can point out that the old adage about “lies, damned lies and statistics” is absolutely true, and the definition of a printed side (as used by the printer manufacturers) has no standing in the real world whatsoever.
If I assume my cartridge statistics are correct, 811 real world A4 impressions costs me all of a black cartridge, 70% of a magenta, 50% of a cyan, and 20% of a yellow. A total of 2.4 cartridges at £60 each, or £144. Which is 18p an impression. Which seems expensive, but given my preponderance of colour printing, perhaps isn’t as bad as it first seems.
