Evaluation
At HP, we typically test multiple products in various environmental conditions to evaluate engine reliability.
We run the products to engine life and test and improve the jam rate, misfeed rate, and supplies’ life.
This kind of extensive, long-term testing is beyond the limits of most companies’ resources; however, it is
possible to estimate their device engine reliability. One option is to compare other products’ duty-cycle
ratings, base warranty (make sure it is at least one-year), and three-year warranty costs. When comparing
the HP LaserJet 3050 AiO with products from other manufacturers, consider the following:
• What is the product’s duty cycle?
• How easy is it to maintain the product?
• Does the product perform consistently under various environmental conditions?
• Are there any paper jams or other failures during your evaluation?
