16 Evaluating MFPs
Evaluation
At HP, we typically test our products in various environmental conditions to evaluate engine reliability. We
run the products to engine life and record the supplies’ life, jam rate, and misfeed rate.
This kind of extensive, long-term testing is beyond the limits of most company’s resources; however, it is
possible to estimate their product’s engine reliability. One option is to compare other manufacturers’ duty-
cycle ratings, recommended monthly page volume, base warranty (make sure it is at least one-year), and
three-year warranty costs. When comparing the HP LaserJet M4345 MFP series with products from other
manufacturers, consider the following:
• What is the product’s duty cycle and recommended monthly page volume?
• Does the product perform consistently under various environmental conditions?
• How easy is it to maintain the product?
• When connected to a network, does the product print correctly every time?
• What does it cost, in both expense and downtime, to replace empty print cartridges?
• Are there any paper jams or other failures during your evaluation?
• What can be said for the reputation of the manufacturer? Can they offer any reliability ratings or claims
of industry leadership?
