"It is a poorly enginnered hardware"0.5 starson by CSHWA
Pros: cheap but deceptive
Cons: When black catridge runs out, you have to spend $300 or more to replace the yellow, the cyan and the magenda catridges at the same time.
Summary: This machine is poorly engineered. It does not gauge the amount of ink left in the catridge. It measures the number of pages went through the printer. It assumes that all 4 inks are consumed equally. When this happened to me the first time, I thought it was coincidence. When it happened the second time, I weighed the catridges. The difference in weight between the new one and the spent one was less than one ounce on all three color cartridges. I spent $39 to buy a consultation phone call to HP's tech support. The person told me that indeed, when one is spent, you have to replace all 4 toners even if all you have been printing were black text.
When my toners on hand run out, I intend to throw this printer to the garbage.
